How to accept the input of both int and float types?

Question

I am making a currency converter. How do I get python to accept both integer and float?

This is how I did it:

def aud_brl(amount,From,to):
    ER = 0.421         


        

Answer 1

this is how you could check the given string and accept int or float (and also cast to it; nb will be an int or a float):

number = input("Enter a number: ")

nb = None
for cast in (int, float):
    try:
        nb = cast(number)
        print(cast)
        break
    except ValueError:
        pass

but in your case just using float might do the trick (as also string representations of integers can be converted to floats: float('3') -> 3.0):

number = input("Enter a number: ")

nb = None
try:
    nb = float(number)
except ValueError:
    pass

if nb is None you got something that could not be converted to a float.
