All we're saying is that the simplest and most accurate way to
determine whether a string can be converted to an int or a float is to
try converting it and see if it succeeds.  If it fails, it will raise
an exception that you can catch using the try-except syntax.  Here's
what your checkint function might look like:

    def checkint(a):
        try:
            int(a)
        except ValueError:
            return False
        else:
            return True
