If you define a function inside another function, then you’re creating aninner function, also known as a nested function. In Python, inner functions have direct access to the variables and names that you define in the enclosing function. This provides a mechanism for you to create helper fun...

By default, sys.breakpointhook() calls pdb.set_trace() expecting no arguments. In this case, it is purely a convenience function so you don’t have to explicitly import pdb or type as much code to enter the debugger. However, sys.breakpointhook() can be set to some other function and...
