input: Write a function to calculate the square of a number and handle exceptions if the input is not a number or is a negative number.
  assert calculate_square(10) == 100
  assert calculate_square(-5) == "The argument cannot be a negative number"
  assert calculate_square('a') == "The argument must be a number"
output: def calculate_square(n):

              return n ** 2
          else:
