Can anyone see what's wrong with this code?

Question

#Am I being silly or should this code be working just fine?

def fund():
money = input("Please enter how much money you have: ")
return money

def check_money(money):
if money == int(money):
return money
else:
return check_money(fund())

check_money(fund())

""" This code is intended to keep asking how much money you have, until you give it a valid integer. Then it should return money """

Answer 1

if money == int(money) is not good.
if money.isnumeric()....

wont work on SL btw

Answer 2

Codeit thanks for answering.. I ended up replacing the whole thing with an exception:

def fund():
fund = raw_input("Please enter how much money you have: ")
try:
return int(funds)
except InputError:
print("You must enter a valid amount...")
return fund()

this seems to work fine
