Multiple Choice

A Python statement inside the if __name__ == '__main__' block of file prog.py:

• is executed only when we directly run prog.py not when prog.py is imported.

• is executed only when we import prog.py into another Python program.

• is executed whenever prog.py is evaluated which means whenever we import prog.py or whenever we run prog.py

• is only executed if we explicitly define a variable __name__ and set it to refer to the string '__main__'

​

​import doctest

​doctest.testmod()

• ​Size or number

• ​Order (or placement)

• ​Dichotomies

• ​Thresholds (or boundaries)
