how to make sure an input is from the wanted type

[wavic]

>>> "2.2".isnumeric()
False
>>> "22".isnumeric()
True
>>> "022".isnumeric()
True
>>> int('000022')
22

Also you can just try/except the user input:

try:
    user_input = int(input("please guess a number between 0 and 10: \n"))
except ValueError:
    print('Not an integer! Please try again!')
