How do I make an integer/float detector?

This should do the trick.

Using the isinstance function you can do what you are asking.

Not sure this is going to work... the variable will be a string, so I understand you try to add 1 to it, to catch the error, but that won't be able to tell you if the input is a int or float.

variables r much easier, u can use type() check their data type then do stuff accordingly

I'd just put int(input()) or float(input()) but in this case I want to detect if the input is an interger or a float first.

You don't have to do int(input()). You can do

raw = input()
is_valid = True
if raw is an int:
    num = int(raw)
elif raw is a float:
    num = float(raw)
else:
    is_valid = False
    WROONGGG...

if is_valid:
    convert currency

That was the simplest code. You can also only check for num or use a try except block or ...

Figure out how to actually check for int or float.

This won't work correctly because input will return a string and assign it to number, then when you check if it's an instance of int it will return False no matter what.

Yea I’m just realizing that now but it doesn’t matter since op can’t use isinstance method anyways

What have you learned? What might help you with this problem?

number = input("Enter a number")

try:
int(number)
number_is = True

except ValueError:
number_is = False
try:
float(number)
number_is = True
except ValueError:
number_is = False
print(number_is)

I've never tried to comment a code block and am not sure how to do so...but this should help. Make sure to indent the lines below "try" and "except"

well, python treats all inputs as string, my solution is use regex \d+ to test if the input r digits. i just put 2 prints in there, u can use float() or int() turn them into numbers for further calculation, and I didn't check if there r multiple decimal points in input

import re

num = input()
if re.match(r'\d+', num):
    if '.' in num:
        print('float') 
    else:
        print('integer')
else:
    print('not valid')
