Numerical operation: the return!

Instructions

Create a file numerical_operations_the_return.py containing the following functions:

• modulo(a, b)
• divide(a, b)
• integer_division(a, b)

We assume that a and b are numbers (int or float).

In case of a division by zero or modulo zero your functions should return 0.

Usage

Here is a possible test.py to test your functions:

import numerical_operations_the_return

print(numerical_operations_the_return.modulo(10, 3))
print(numerical_operations_the_return.divide(10, 3))
print(numerical_operations_the_return.divide(10, 0))
print(numerical_operations_the_return.integer_division(10, 3))

$ python test.py
1
3.3333333333333335
0
3
$

Hints

• Some operations will panic in special cases (like division by zero), it is very important to always account for those cases and handle them properly in order to avoid bugs.
• In Python 2 a division with two integers will return an integer, in Python 3 it will return a float. We assume you are using Python 3, in case you want to force the Python 3 behavior you can cast one of the operands to float like so: float(a).
