[Tutor] Looking for some direction
I'm a long time IT professional trying to teach myself object-oriented programming. As such I want to build a traditional PC app using MVC (Model - View - Controller) architecture. Just want to make sure I'm heading about this in the best way so I'm looking for some direction. For the Model or persistence layer I want to use SQLite. For the View or GUI I want to use wxPython. For the Controller I want to of course use Python. I'm also planning on using Git for source control. 1) For the IDE I'm most comfortable with Netbeans/Java, but I'm forcing myself to try and get comfortable with PyCharm. Is it worth sticking it out with PyCharm, or should I go with the Python module in Netbeans? Or is there another IDE I should look at? 2) For wxPython I'm finding a lot of the documentation is outdated. Is this book any good: http://www.blog.pythonlibrary.org/2019/05/08/creating-gui-applications-with-wxpython-now-available/ Or is there a better book/course/website I should be working with? Or is there a better grahpics framework at this point for a traditional desktop app? 3) For the O-O part, I'm comfortable with Inheritance and Composition. Do I need to worry about any of the more advanced design patterns? This app will be for vehicle ownership - tracking maintenance, etc. Nothing fancy. 4) I plan to write my Use Case in Libre Office Write. For the UML diagrams, is there a simple app to handle that? I don't need it to generate code but I'd like to have a nice class diagram if possible. 5) I'm really having trouble envisioning the GUI screens. How does one get a handle on that? Just draw the screens on paper, or what? Any ideas very much appreciated. -- Frank L. "Cranky Frankie" Palmeri, Risible Riding Raconteur & Writer "I never lose.

[Tutor] pygame blinking text
My Python presentation is just about complete. As a nice ending I want to do a pygame program that displays the group's .jpg, with the words Thank You! blinking, say on for a second and off for a second. Unfortunatley, I can't get the works to blink, but I can get them to appear for a short time: from livewires import games, color games.init(screen_width = 640, screen_height = 480, fps = 50) bg_image = games.load_image(AEMUG640x480.JPG, transparent = False) games.screen.background = bg_image ty_message = games.Message(value = Thank You!, size = 100, color = color.red, x = games.screen.width/2, y = games.screen.height/2, lifetime = 100, after_death = 0) games.screen.add(ty_message) games.screen.mainloop() I tried putting the ty_message block in a WHILE TRUE loop, and that didn't work. Then I tried the same with the games.screen.add(ty_message) line and that didn't work either. I think what might work is if I can find a way to delete the ty_message and readd it, over and over in a loop with a delay, bu: games.screen.delete(ty_message) doesn't work - delete is not a valid method. Is there any way to get blinking text with pygame? This is not a deal breaker, but I thought the blinking text would be neat. -- Frank L.

[Tutor] What style do you call Python programming?
I'm looking for a term to call the kind of Python programming that Python is, in other words, programming with no branching, no GOTOs, no statement labels and no line numbers. I'm tempted to call it Structured Progamming, but we had that in COBOL, and this is not like COBOL. It seems to be with Python the whole thing is creating functions and then using loops, with an occasional BREAK or CONTINUE, to control program flow. I know it's Structured, but it's not like COBOL structured, if you know what I mean. I hope this is clear enough. -- Frank L.

[Tutor] What style do you call Python programming?
I appreciate all the comments in this thread so far, but what I'm really looking for is what to call the style of programming where you have no direct branching via line numbers, statement names, and gotos. I'm finding that lacking these things that I've been familiar with in other languages is good, in that it forces you to really think through the best way to organize the logic. It seems to me that this is such a big departure from traditional procedural styled programming there ought to be a name for it, other than structured programming, since you can code that way even with line numbers, etc. I'd also be interested in reading the Python history file. -- Frank L.

You can write object oriented code in hex if you really want, it doesn't make raw machine language object oriented. Probably because I work in a shop that still heavily uses older languages like COBOL and CULPRIT where you still deal with labels, branching, goto, etc. The fact that it is possible to code structured that way AND the Python way amazes me. -- Frank L.

[Tutor] tkinter message button questions
I have a program I'm testing in Python 3.1 in Windows XP using tkinker to dispay random quotes. It works except for two things. 1) The program displays a random quote of the day when it's invoked, but I want to have a Next quote button so that additional random quotes can be displayed. Here are the parts of the program were I get the first quote: def get_random_quote():# create a function to get a random quote from quote_dict rq = (random.randrange(len(quote_dict))+1) # pick a random entry from the quote dictionary return rq def output_quote(): rand_quote = get_random_quote() # get a random quote quote = quote_dict[rand_quote][1] # put the quote in a string varible author = quote_dict[rand_quote][0]# put the author in a string variable om = (quote+\n\n+author) # format the output string variable return om out_message = output_quote() msg_widget = Message(win, anchor = NW, justify = LEFT, width = 1000, bd= 2, bg = white, relief = SOLID, text=out_message) Here is my button the get the next quote: next_button = Button(win, text=Next Quote, command=output_quote()) # create button widget next_button.pack(side=LEFT) Even though I'm calling the same function, output_quote(), the screen is not getting refreshed. There is no error, just the new quote is not showing up in the message box. How do I refresh the message box? 2) The message widget seems to be sizing based on the size of the text you present to it. For a small quote it's small, for a longer quote it streches out wide and then adds more lines. I'd like to present a consistent sized message box when the program is run, no matter if the text is small or large, but I can't figure out how to do that. In other words, I'd like the message widget in question 1 above to display as a box capable of storing, say, 1,000 characters, even if I only give it 100, so the program looks the same every time it's invoked. Is there a way to make a default sized message widget? -- Frank L.

[Tutor] sensing EOF in Python 3.1
From: Steven D'Aprano st...@pearwood.info wrote: Pickle does standard file I/O in the same way that opening a JPEG in an image view does standard file I/O: both programs read data from a file the standard, ordinary way, but expect data of a certain format. If you provide it too little data, you will get an EOF error. If you provide too much data, or messed up data, then you will some other error. But the file I/O is exactly the same. It's just that pickle, or your image viewer, handle it for you. Right, thanks. Pickling won't tell you anything about Python data structures. Pickling takes Python data structures, bashes them with a hammer until they stop wiggling, then runs them through a serialiser turning them into a stream of text or binary codes. I want to include this info in my presentation because it shows how data structures can be externalized. Pickles tell you only about pickles. You won't learn anything about (say) dicts by looking at a pickled dict except the bare fact that dicts can be pickled. Still though, that is important. import pickle # import the pickle module Really? Wow! I thought import pickle meant sort the database!!! *wink* Sarcasm aside, what else could import pickle mean other than import the pickle module? I was trying to put a comment on every line because the audience who will be looking at this will have never seen any Python before. The comment adds absolutely nothing to the code. At best it is superfluous. At worst it is harmful, because code and comments have a regrettable tendency to get out of sync. I know what you mean. The commens could be meaningful at first, then the code gets edited over the years and the comments don't get updated. I've seen that many times. Every comment should carry its weight. If the code is particularly convoluted, you might write comments explaining *how* you do something, but generally the code speaks for itself regarding the how, so comments should explain *why* you do something. If a comment doesn't tell you something that the code doesn't, that you need to know (or at least should know). Otherwise it should be throw out into the back alley for the stray cats to eat. Again, in this specific instance, this simple example code is intended to be looked at not by Python programmers, or even programmers, but rather by database professionals who I am attempting to expose Python to for the first time. pickle_file = open(d:/Work/pickle_file, rb) # open the pickled file read_list = pickle.load(pickle_file) # read the first pickled row And this is what I'm talking about. It does NOT read the first pickled row. Pickles don't have rows. In this case, you are reading the first and only pickled object, which happens to be a dict. You are of course, correct, thanks. I'll be fixing that. Steven thanks for your comments about comments, I'll be doing them over for sure. -- Frank L.

[Tutor] Python 3 dictionary questions
In playing around with Pyton 3 dictionaries I've come up with 2 questions
1) How are duplicate keys handled? For example:
Qb_Dict = {Montana: [Joe, Montana, 415-123-4567,
joe.mont...@gmail.com,Candlestick Park],
Tarkington: [Fran, 651-321-7657, frank.tarking...@gmail.com,
Metropolitan Stadidum],
Namath: [Joe, 212-222-, joe.nam...@gmail.com, Shea Stadium],
Elway: [John, 303-9876-333, john.el...@gmai.com, Mile High Stadium],
Elway: [Ed, 303-9876-333, john.el...@gmai.com, Mile High
Stadium],
Manning: [Archie,504-888-1234, archie.mann...@gmail.com,
Louisiana Superdome],
Staubach: [Roger,214-765-8989, roger.staub...@gmail.com,
Cowboy Stadium]}
print(Qb_Dict[Elway],\n)# print a dictionary entry
In the above the wrong Elway entry, the second one, where the first
name is Ed, is getting printed. I just added that second Elway row to
see how it would handle duplicates and the results are interesting, to
say the least.
2) Is there a way to print out the actual value of the key, like
Montana would be 0, Tarkington would be 1, etc?

[Tutor] Thank you!
Thank you to all for your help on my SQL DDL parsing script, and thank you Alan for having this wonderful list. I got the program to work and verified the DDL is being parsed correctly. I've been working as a database administrator for many years, but before that I programmed on the mainframe. I'm used to COBOL, SQL, DB2, and latley XML. I've done some Unix scripting and VB script, taught myself some basic C and C++, with some odd Visual Basic along the way, but Python is enitirely new to me. That's why I got thrown off with the output not lining up in Notepad - I've never written anything before that could be displayed in a mode that used proportional fonts. The things I like about Python: - the forced indentation makes for really readable code - it's free! - it can be used on any platform - it can be used for scripting or for builing a stand alone program - it can work in any programming style (O-O, sturctured, etc.) I'm going to be doing a presentation on Python programming for database administrators. This script will help a lot to explain some of the basic concepts. Thanks again very much for your help. Python rocks! -- Frank L.

[Tutor] interesting behaviour with postional output
I'm working on writing out postional output. When I use this statement:
print('%-40s%s' % (element_list[0], element_list[1]))
I get nice, lined up columns on the screen. When I write to a file like this:
new_line = ('%-40s%s%s' % (element_list[0], element_list[1],'\n'))
file_out.write(new_line)
a very funny thing happens. When I open the file in Notepad, the
columns are not lined up, however when I switch the font to Courier,
they * are* lined up. So what's happening is the output statement is
working correctly - the second column starts in the 41st postion - but
you have to use a non-proportional font to see it.
I was hoping to not have the font be an issue.
Very interesting.

[Tutor] positional output
Thank you for your help on this. Now for the rest of the story. I'm trying to build a script to parse IBM AIX DB2 DDL to line up the data types (it drives me crazy when the column data types are not lined up). For example, typical create table DDL might be hundreds of lines long but will look like this: -- -- table create DDL -- CREATE TABLE FRANK.TEST ( COLUMN1 DECIMAL(8), COLUMN2 CHAR(20), COLUMN3TIMESTAMP, COLUMN4 INTEGER, COLUMN5 DATE NOT NULL WITH DEFAULT, -- repeat for hundreds of columns ); COMMENT ON TABLE FRANK.TEST IS 'TEST TABLE'; This is just a small sample, there are many other possible lines, but I'm only concerned about the column lines like COLUMN1 through COLUMN5 above. I have a script on Windows that reads in the DDL file and writes out each line to a new file. What I'm doing is using the split() function to test for the presence of any DB2 standard data type, like CHAR, INTEGER, SMALINT, etc. If I find one I want to use positional output to make each like look like: COLUMN1DECIMAL(8), COLUMN2CHAR(20), COLUMN3TIMESTAMP, COLUMN4 INTEGER, COLUMN5 DATE NOT NULL WITH DEFAULT, where all the COLUMNs would be in column 1 of the output file, the data types would be in column 40, and the comma would be next. The problem is handling lines that have NOT NULL WITH DEFAULT at the end. The thing is there could be other valid DDL in that position, and there may or may not be a comma after the data type. What I want to do is just take anything after the datatype, which would be element(1) in the split() output, and just write it out. I thought I could use rsplit() to do this, but you can't put the output of split() in rsplit() - I tried. I need to do something like, after verifying that element(1) is a valid DB2 datatype, just take everything else on the line after it, which may be a single comma, or NOT NULL WITH DEFAULT, or something else, and place it on the output line to be written out. So, to reiterate: I'm trying to build a script to line up the data types in a create table DDL file. Splitting each line into individual space separated elements, then checking for a valid data type, the rebuilding the line positionally seems to be the way to go. If there's an easyier way to do it I'm all ears. I don't have my script available at the moment but I could send it if it would be helpful. -- Frank L.

[Tutor] string split function - how to tell how many splits
How do you tell how many splits the string split funtion returns? For example:
field = 'The Good Wife ;' # a string separated by spaces
new_list = field.split(' ') # create a list of space delimited elements
print (new_list[0]) # print the first one
print (new_list[1]) # print the second one
print (new_list[2]) # print the third one
print (new_list[3]) # print the fourth one
print (new_list[4]) # print the fifth one
The last line above causes an error. I plan on reading in a file where
I don't know what the number of splits will be. How can I find out
before trying to access an out of range index?

[Tutor] Intro
Hi Python tutor listers, as an intro I'll repost what I sent to my Linux groups, since one of their members turned me on to you: Before Borders imploded I'd joined their club so they'd send me 50% coupons now and then. One afternoon last year I was in the store browsing the computer books and this Python book caught my eye. I knew very little about Python but I knew it had a good rep and I love Monty Python so I bought the book then put in on the shelf. Only recently did I get around to reading it and I only wish I'd done so sooner, it's that good. The book is Python Programming for the Absolute Beginner, Third Edition by Michael Dawson, Course Technology, ISBN-13 978-1-4354-5500-9, published in 2010. He presumes you know nothing about programming and then uses simple computer games to demonstrate the power of Python. He starts with those text based games many of us used to play, finishing off with GUI based games with music and animation, and all the code is downloadable from the publisher's web site. That's pretty good for a beginner book, I'd say. Python itself is a beautiful language. Because it uses indenting for constructing programming blocks, not semi-colons or braces, the code is inherently clean and crisp. More about Python: - it's easy to learn yet very powerful - very concise and tight syntax - comes with it's own IDE - no compiling yet can create stand alone apps - can be used for scripting or full blown applications - runs on all the major OSs - no variably type declarations, it can infer them - lots of modules (pre-coded specific code routines) available - can get productive quickly - can code in a procedural or object-oriented style Here's the typical introductory Hello World program: print(Hello World) Doesn't get much simpler than that! He even gets into GUI programming, event driven design, sprites, etc. For a book for a supposed absolute beginner I think that's amazing, because I can see someone getting this even if they really have no coding background. That's how clearly it's written and how clean and clear the example code is. One more side benefit of this book: it contains the gentlest, easiest to digest introduction to object-oriented programming I've ever seen, and I read a lot of computer stuff. If you're an old-timer like me who only studied procedural languages, this is about as easy an introduction to the power and flexibility of O-O programming that you will ever find. What I've been wanting to do for a long time is write an app that, when my computer starts, displays a window with a quote of the day. With this book I now have several ways to take my huge collected quotes file, import it into arrays in a Python program, apply a random function, and display a random quote each time I log on. That kind of app is a natural for Python, but don't kid yourself - he actually writes a space invaders type game using some game modules - and this in a beginner book! Amazing. This is a great book about a great language. -- Frank L.

As I said, I read a *lot* of computer books (I'm a database administrator) and this book really stands out. It's so good I'm thinking of seeing if my wife, who knows nothing about programming, would like to read it. I've never felt that way about a computer book before, and since this is so unusual in the computer book field, I thought I'd share it here. For what it is worth, I hate all those games. I'm not a gamer either, but this paradigm allowed the author to show the great flexibility of Python. I think he made a wise choice. Using games as a starting point should also make this book useful to teachers of programming 101, because kids love games. Anything that gets kids coding instead of just wasting time is good IMHO.

Re: [Tutor] Intro
I'm trying to decide what would be better: - reading the huge quote file (hundreds of entries, two strings, author and quotation) in each time the program starts - loading the quotes into an array in the program I'd like to be able to add new quotes easily, so that is a factor as well. I'm satisfied to use a dialog box, I don't need a GUI at this point so no tkinter (yet).
