The if statement is used to skip the code after the if statement in
certain situations. If that if statement is in a file named test1.py,
and you issue this command:
$ python test1.py
then the code after the if statement will execute. That's because
python assigns the string '__main__' to the variable __name__ when the
program starts
However, if you do this:
-------
#test1.py
def my_func(num):
print num * 2
if __name__ == "__main__":
print "Testing my func:", my_func(10)
--------
#test2.py
import test1
test1.my_func(5)
-------
...and you issue the command:
$python test2.py
Then the code after the if statement in test1.py will not execute.
