Debugging Python Code

Debugging python code is extremelly simple and powerfull. Just use ipdb for this purposes:

pip install ipdb

Then open up your code and in the place where you need code to stop insert this:

import pdb; pdb.set_trace()

When you refresh the browser or execute a .py file, code execution will stop in this place and controll will be passed to a command line. There you can do whatever you want, like inspect local variables with

locals()

inspect global variables with

globals()

or execute any other functions. To continue just type

c

That's a real power! Compare it with PHP's pre, print or var_dump approaches.
