Exception handling print statements not working, but error types are?

My code is below. The exception handling itself works, but I am unable to get the error messages specified to print.

import numpy as np
def compute_circle_area(r):
    try:
        if type(r) == 'complex' :
          raise(TypeError('Argument is complex'))
        elif r < 0 :
          raise(ValueError('Argument < 0'))
        elif type(r) == str :
          raise(TypeError('Argument is wrong type'))
  
        a = np.pi * r * r

    except ValueError as ve:
      print("Value Error", ve)
    except TypeError as te:
      print("Type Error", te)
    else:
      print('Argument works, solution is: ', a)
    finally:
      print("Let's continue")

print(compute_circle_area(2.1))
print(compute_circle_area(2+1j))
print(compute_circle_area(-2.1))
print(compute_circle_area('radius'))
