It returns
the flow of control to the calling function. It also returns
output/results to the calling function.
Consider the function below:
def am_i_wrong(answer):
if answer == 'yes':
return True
else:
return False
You have multiple returns. So return
doesn't simply end the function definition. It instead is the point at which the function returns the result to the caller.
If answer
is equal to 'yes' then anything after the if statement (after if and else) is never run because the function has already returned.
