Debugging

• Write the following code to use an interactive debugger in Python.

import pdb
pdb.set_trace()

Self

• Passing a reference to self seems repetitive.

class Foo:
  def bar(self)
    print('Hello')

Testing

• You need to pass in the -s to print test output. I expected print to log output regardless.

Modules

• You can conditionally implement different behavior when importing modules in Python.
• Taken from this StackOverflow example.

def func():
    print("func() in one.py")

print("top-level in one.py")

if __name__ == "__main__":
    print("one.py is being run directly")
else:
    print("one.py is being imported into another module")

import one

print("top-level in two.py")
one.func()

if __name__ == "__main__":
    print("two.py is being run directly")
else:
    print("two.py is being imported into another module")

Running python one.py returns: top-level in one.py one.py is being run directly

While running python two.py returns: top-level in one.py one.py is being imported into another module top-level in two.py func() in one.py two.py is being run directly
