I have a need to identify comments in different kinds of source files in a given directory. ( For example java,XML, JavaScript, bash). I have decided to do this using Python (as an attempt to learn Python). The questions I have are

1) What should I know about python to get this done? ( I have an idea that Regular Expressions will be useful but are there alternatives/other modules that will be useful? Libraries that I can use to get this done?)

2) Is Python a good choice for such a task? Will some other language make this easier to accomplish?

    Your problem seems to be more related to programming language parsing. I believe with regular expressions you will be able to find comments in most of the languages. The good thing is that you have regular expressions almost everywhere: Perl, Python, Ruby, AWK, Sed, etc.

    But, as the other answer said, you’d better use some parsing machinery. And, if not a full blown parser, a lexer. For Python, check out the Pygments library, which has lexers for many languages already implemented.
