[Tutor] Help installing Python3 in a particular folder

Re: [Tutor] Problems understanding code output
I'm not really sure what you are asking, but the formatting for your code is pretty screwy.

[Tutor] Cannot understand what this means
Hello All, I have just started out with python and was feeling pretty comfortable and confident to the point of solving problems from websites. But now, there is a program from Google's Python Exercises whose main() part is already given to you. def main(): # This command-line parsing code is provided. # Make a list of command line arguments, omitting the [0] element # which is the script itself. args = sys.argv[1:] if not args: print 'usage: [--summaryfile] file [file ...]' sys.exit(1) # Notice the summary flag and remove it from args if it is present. summary = False if args[0] == '--summaryfile': summary = True del args[0] The problem is one where you have to define a function to read a html file containing the 1000 most popular baby names of a particular year(separate files for different years) and print each name in alphabetical order with their corresponding rank for that year. My problem is that I cannot understand anything in this main() module. Nothing at all. So can somebody please explain what this means and what is its significance?

[Tutor] Interpret the contents of a line
Hi, I am working on a parser and my input file is a description about bunch of things written line by line. So for instance, consider the following two lines and what the corresponding variables in python should look like. example Line1: position = 1, 1, rotation = 90, 0, 0, mass = 120; Here I want the variables to be position = [1,1,0], rotation = [90,0,0], mass = [120] example Line2: position = 1, 1, 2, mass = 120, rotation = 90, 0; Here I want the variables to be position = [1,1,2], rotation = [90,0,0], mass = [120] example Line3: mass = 120, rotation = 90, 0; Here I want the variables to be position = [0,0,0], rotation = [90,0,0], mass = [120] I know the maximum number of arguments possible for each variable. For example, in the first line above, only two numbers for position ares specified; that means that the third entry in position list is zero. So I need to handle these cases while reading in the file as well. Additionally, the text might not always be in the same order; like shown in the second line above. And finally, sometimes numbers for one variable might not exist at all; like shown in line 3. Here, the position is then read as position = [0,0,0]. How do I implement such stuff? Is there some smart way of doing this? All I have in mind is this: read a line as comma or a space delimited list of words variable and then some how use if else + len(list) to figure out whats going on. But that seems way too tedious and I feel that there might be an easier way to read such things. Any help is highly appreciated.

Re: [Tutor] A list of 100+ projects to complete to master Python.
First thing you should learn is offsite backups, I've lost several projects in the works because of a hd mishap. Secondarily, I would recommend using existing primarily used python projects to 'reinvent the wheel' so to speak. Thirdly, make sure the code is properly documented, and serves a purpose. And lastly, utilize other programs with python api's, such as blender, which can make your apps pop, or diversify into game development kits.

I think I've covered about 50-60% of the recommended reading and about 75% of the topics. But... I think its a tad old fashioned and neglects the biggest areas of weakness and growth in my experience of modern software engineering - large scale systems. More and more systems don't run on single hosts. They don't even run on single CPU architectures within a single box(the mention of GPU processing and CUDA hints at that). But learning parallelism on a single computer is only the tip of the iceberg. The vast majority of corporate programming today builds systems running across dozens and sometimes hundreds of physical servers. (One CRM implementation I did had over 200 servers across 3 sites all integrated and self managed as part of the project design.) There is one disparaging comment about UML but UML is about the only tool we have for documenting large scale systems effectively. It's far from perfect but a critical skill for grads IMHO. (Ironically it's usually taught as a tool for designing OOP programs with a few classes and that is its weakest area of application.) The other problem in all of this is that it is effectively impossible to teach all of that in a standard 3 or 4 year Bachelors course. Even with 2 years extra for a Masters degree. I did my degree in Electrical/Electronic engineering with specialism in software. It took me about 5 more years to read up on all the CS bits I wanted to cover that weren't in our course. I discovered these areas by discussion with colleagues who had attended other colleges or done other degrees. None of us had done all that was needed. And that's the problem. Computing has become too widely encompassing for anyone to learn the breadth of material needed in the time available in an undergraduate and/or masters course. Other engineering/science disciplines have addressed this by specializing and that is already happening with Games programming degrees becoming increasingly common and many courses in Business computing. I think we will see more of this in the future. It's simply unrealistic to ever expect college grads to have the breadth suggested in the article - they may aspire to it and maybe after 10 years or more attain it. But by then there will be another array of paradigms to absorb... -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

If you only want to fulfill the test once, here is a way without a loop, using a list comprehension. A list comprehension *is* a loop. It even includes a for inside it. I really don't understand why people so often say things like I have a bunch of stuff to do repeatedly, but I want to do it without a loop. To put it another way, I want to repeat something without repeating it. WTF??? The only way to avoid a loop *somewhere* is to have a parallel-processing computer with at least as many parallel processes as you have things to repeat. So if Hs has 300K lines to process, he would need 300K processors, one per line. Since that's impractical unless you're Google or the NSA[1] you're going to need a loop, the only question is whether it is an *explicit* loop or an *implicit* loop. For example, a standard for-loop: for line in many_lines: process(line) or a list-comprehension: [process(line) for line in many_lines] are explicit loops. The map built-in is implicit: map(process, many_lines) So are many of numpy's array functions. But regardless of whether *you* write the loop, or Python does it for you, there is still a loop.
