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

Use the isinstance function, which is built in

if isinstance(num, (int, float)):
    #do stuff

Also, you should refrain from using reserved keywords for variable names. The keyword from is a reserved keyword in Python

Finally, there is one other error I noticed:

if From == 'aud' or 'brl'

Should be

if From == 'aud' or From == 'brl'

Lastly, to clean up the if statements you could theoretically use the list (if you have more currencies in the future, this might be better.

currencies = ['aud', 'brl']     #other currencies possible
if From in currencies and to in currencies:
    #do conversion
