Say we have written the following code and saved it as a Python file called "arithmetic.py$"$:

def mult$($num$\_1,$ num$\_2)$:

$"""$Returns the product of two numbers"""

return num$\_1*$ num$\_2$

def add$($num$\_1,$ num$\_2)$:

$"""$Returns the sum of two numbers"""

return num$\_1+$ num$\_2$

result $=$ mult$(3,5)$

print$($result$)$
