0-add_integer.py, tests/0-add_integer.txt:

Write a function that adds 2 integers.

Prototype: def add_integer(a, b=98):

a and b must be integers or floats, otherwise raise a TypeError exception with the message a must be an integer or b must be an integer

a and b must be first casted to integers if they are float

Returns an integer: the addition of a and b

2-matrix_divided.py, tests/2-matrix_divided.txt:

Write a function that divides all elements of a matrix.

Prototype: def matrix_divided(matrix, div):

matrix must be a list of lists of integers or floats, otherwise raise a TypeError exception with the message matrix must be a matrix (list of lists) of integers/floats

Each row of the matrix must be of the same size, otherwise raise a TypeError exception with the message Each row of the matrix must have the same size

div must be a number (integer or float), otherwise raise a TypeError exception with the message div must be a number

div can’t be equal to 0, otherwise raise a ZeroDivisionError exception with the message division by zero

All elements of the matrix should be divided by div, rounded to 2 decimal places

Returns a new matrix
