An alternative to adding/removing/commenting out/uncommenting print
statements through your code may be to use decorators. A decorator is
a a function that is passed your function whenever it is called. A
decorator can do whatever you want. Some of the possibilities are
caching values of the function, but a decorator might be used to print
debugging statements or keep track of how many times a method is
called (or even pause or wait for input). Some IDEs might have step
through and breakpoint capability. If my memory serves me correctly,
there is a command (I think it works only in the command line, not in
the notebook) that will give timing and method invocations for code.
@somedecorator
def somefunction():
code
When somefunction is called, somedecorator (which is actually another
callable function somewhere) gets called.
Hope this helps.
