Re: [Tutor] input with default value option

Hi Phon,
We can build your own function to do this. Bob showed how to set up code
so that the default's taken if the user just presses enter in his reply.
Let's take a look at it again:
###
response = raw_input("Enter some data:")
if not response: response = "default value"
###
We can capture this as a function that takes in a question and a default
answer:
##
def ask(question, default):
response = raw_input(question)
if not response:
response = default
return response
##
And now we have something that acts like raw_input(), but also gives the
user the ability to get a default:
##
>>> ask("favorite color?", "Blue. No yellow -- aaaugh!")
favorite color?red
'red'
>>> ask("favorite color?", "Blue. No yellow -- aaaugh!")
favorite color?
'Blue. No yellow -- aaaugh!'
>>>
##
(In the second call to ask(), I just pressed enter.)
Does this make sense?

Re: [Tutor] failing to learn python
> I am a parttime sys admin so I want system admin problem which usually I > do through shell scripts like parsing logs, generating reports, greping > with regexes etc. Hi Payal, You might also find David Mertz's book "Text Processing With Python" to be useful for you: http://gnosis.cx/TPiP/ I agree with the other recommendation on "Dive into Python": it provides a lot of good practical programming knowledge. http://diveintopython.org/ > The only thing I don't want is silly problems like generate fibonnacci > series, add numbers from 0-n etc. non required silly stuff. Just as a counterpoint: some of those silly things aren't useful in their own right, but they're finger exercises to help one really get mastery over the language. Recursion is one of those things that are core concepts, and most Python tutorials try to cover it by talking about factorials. It's very unfortunate that fibonacci numbers are one of the "classical" examples of recursion, since they are useless to most people. But don't discount recursion altogether. We can look at concrete example of recursion that might be more applicable. One common system administration question that pops up every once in a while is: "How do I do [some_action] to every file in my directory?" We can either know magically that os.walk() will do the hard work for us, or we can use a combination of os.listdir() and os.path.isdir(): # ### pseudocode def my_walk(some_action, dir_or_file): if os.path.isfile(dir_or_file): some_action(dir_or_file) else: for thing in os.listdir(dir_or_file): my_walk(some_action, thing) # in which there's a specific "base" case for handling regular files, and an "inductive" case for handling directories. Another example of this kind of processing involves things like XML or HTML processing. If we wanted to get all the anchor link elements in an HTML document, how would we do this? We again break it into two cases: one to handle anchor elements, and another to handle anything else: ## ## Pseudocode def get_anchors(element): if element is an anchor: return [element] else: anchors = [] for child in element.children: anchors.extend(get_anchors(child)) return anchors ## We're in a slightly different domain, but if we look at this with a critical eye, we should see that the code structure is similar to the directory-walking example. There's a case for handling really simple problems, and another case for handling slightly harder problems. That's the key insight you should have been getting. If the tutorials that you're reading haven't been delving into this, that means that those tutorials aren't doing a good job. The fact that factorial() looks like: def factorial(n): if n == 0: return 1 else: return n * factorial(n-1) is pretty darn worthless in itself. But the idea that we can break things down into two categories (simple cases, slightly complex cases) and handle them in some structured way is a valuable concept. If you see something that's looks trivially un-useful when you're reading a tutorial, bring it up on this list. They're bound to be some kind of real application for it. *grin* And if you have any other questions, feel free to ask.

The problem is slightly weird, just because you need to clarify what it
means to take the length of a non-list. From the examples above, it
sounds like we'd like to define the "length" of a non-list to be one. Is
that right?
Can you write a function called length() that takes a thing and returns
the "length" of that thing?
##
def length(something):
... ## fill me in
##
For example, we'd like to see:
length("spam!") ==> 1
length(2) ==> 1
length(['Ted', 'Rock']) ==> 2
If you can define this you should be able to use this to solve your
problem.
When you're defining length(), you may find the built-in function "type()"
useful. For example:
##
>>> type(5)
>>> type([1, 2, 3])
##
Good luck!

Lengths of strings express the number of characters. You could check to see if it's a grouping-type of element -- i.e., a list, tuple or set -- but I think your better approach is that, if this is something you need, make all of the elements lists, some of which are single-item lists; for example, instead of: list1 = [ 'spam!', 2, ['Ted', 'Rock'] ] use: list1 = [ ['spam!'], [2], ['Ted', 'Rock'] ] >>> list1 = [ ['spam!'], [2], ['Ted', 'Rock'] ] >>> for item in list1: ... print item, len(item) ... ['spam!'] 1 [2] 1 ['Ted', 'Rock'] 2 If your heart is set on the other approach, though, it can be done: >>> list1 = [ 'spam!', 2, ['Ted', 'Rock'] ] >>> for item in list1: ... if isinstance(item,(list, tuple, set)): ... print item, len(item) ... else: ... print item, 1 ... spam! 1 2 1 ['Ted', 'Rock'] 2 >>> ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Question about list
Hi Hoffman, It is often useful to use the "for" construct to process items in a list. e.g.: >>> list1 = [ 'spam!', 2, ['Ted', 'Rock']] >>> for item in list: ...print item spam! 2 ['Ted', 'Rock'] If you pass a list to the len() function, it will return the number of elenents in the list. e.g.: >>> x = ['a', 'b', 'c'] >>> len(x) 3 Now if you pass len() a string it will return the length of a string: >>> y = 'hello' >>> len(y) 5 Given your list below, len() will return what you're looking for when it encounters the third element of the list, but won't for the first and second elements. One way to solve this problem is to use the type() function to figure out if your item is a string or list and use len() as appropriate. I hope this provides enough of a hint. -mtw On Mon, Apr 10, 2006 at 03:29:23PM -0700, Hoffmann ([EMAIL PROTECTED]) wrote: > Hello, > > I have a list: list1 = [ 'spam!', 2, ['Ted', 'Rock'] > ] > and I wrote the script below: > > i = 0 > while i < len(list1): > print list1[i] > i += 1 > > Ok.

For example, the len() function will tell us that ['Ted', 'Rock'] has two elements.

When I hear the word "silly" I assume that you are comfortable with programming in Python, and do not need the examples that are useful to beginners, and want access to libraries of code for doing the tasks you described. So I suggest you look at Python's remarkable set of modules. In the docs you'll find Global Module Index. Start with re for regular expressions, glob & shutil for some file management, os for more file and process management. Some of these have some example code. Select ONE task of interest to you, make your best stab at writing a Python program using the module, then come back with the program and tell us how we can help you with it. If my assumption is inaccurate, and you do need help with the fundamentals of Python, then I suggest you tackle some of the assignments in the references you have *as a way of becoming comfortable with Python*, then tackle the modules I mentioned. Someone else on this list may point you to online learning resources that will meet your need for more information at low-to-no cost.

You need to understand the basics like loops, functions, lists and dictionaries to solve most real-world problems. When you have questions about basic concepts you can ask for help on this list. You might like to look at "Python Programming for the absolute beginner". It is oriented to beginners and has many examples and exercises. http://premierpressbooks.com/ptr_detail.cfm?group=Programming&subcat=Other%20Programming&isbn=1%2D59863%2D112%2D8 What kind of real life problems are you interested in? You might like "Beginning Python", it has several real-life projects. http://apress.com/book/bookDisplay.html?bID=10013 When you have questions about basic concepts you can ask for help on this list. We do best with questions that are very specific. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] failing to learn python
Hi, I am trying to learn Python seriously for almost 2 months but have not gotten far at all. Infact, it seems I have not understood even the basic concepts itself. I know some shell, sed and awk programming. I have tried reading Learning Python - Mark Lutz Think C Spy A byte of Python Non-Programmers Tutorial For Python etc. But I have not got anything from them. I am feeling that they are superficial and do not touch real life problems. Also, not enough examples are provided which can help newbies like me. Can anyone help me, it is pretty pretty frustating thing for last couple of months? With warm regards, -Payal ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
