One Trick for Debugging Python

I just learned one trick for debugging Python script from my colleague. It’s not such magical maybe most of Pythonistee have already used it everyday), but I think it is very useful to debug Python script.

I only need to add single line at the position I want to break.

import code; code.interact(local=locals())

After that, run Python script as usual. Python Interpreter will stop at your break point and launch a REPL (Read–eval–print loop) console. You can print out variables to debug.

In Ruby, we can use Pry as the same way to debug Ruby script.
