Test for Numeric in Prime Python
Since MicroPython doesn't have the isnumeric() attribute, here's a little function that can determine if a string consists of only digits or not:

Code:
# this function returns True if the argument is numeric, False if not
def isnumeric(number):
    for i in number:
        if i<'0' or i>'9':
            return False
    return True

This can be used after an input to make sure only digits have been entered. Decimal points and exponents are not allowed.
