Question

I do most of my development in Java and C++ but recently had to write various scripts and picked up Python. I run python from the command line on scripts; not in interactive mode. I’m wondering if

I like a lot of things about the language, but one thing that keeps reducing my productivity is the fact that I get no advance warning if I am using a variable that is not yet defined.

For example, somewhere in the code I forget to prefix a variable with its declaring module, or I make a little typo, and the first time I learn about it is when the program crashes.

Is there a way to get the python interpreter to throw advance warnings if something might be funky when I access a variable that hasn’t been accessed or set somewhere else in the program? I realize this is somewhat against the philosophy of the language, but I can’t be the only one who makes these silly errors and has no way of catching them early.

Pydev is pretty well integrated with Pylint, see here — and pylint is a much more powerful checker than pyflakes (beyond the minor issue of misspelled variables, it will catch style violations, etc, etc — it’s highly customizable for whatever your specific purposes are!).
