Python: Some float (strings) convert to integers, others don't-CodePudding

Why do some floats convert to integers and others don't in this Python code?

I've tested the following code with various floats as input (e.g. 11.1, 11.5, 44.5, 22.5, etc.) and sometimes the code returns, for example, "x is 11" and sometimes it returns "x is not an integer." Why?

    def main():
        x = get_int("What's x? ")
        print (f'x is {x}')

    def get_int(prompt):
        while True:
            try:
                return int(input(prompt))
            except ValueError:
                print("x is not an integer.")
            try:
                return int(float(input(prompt)))
            except ValueError:
                print("x is not an integer.")
            else:
                return x

    main()

This is what you were thinking of. If it works as an integer return it. Otherwise, try that SAME STRING as a float.

def main():
    x = get_int("What's x? ")
    print (f'x is {x}')

def get_int(prompt):
    while True:
        i = input(prompt)
        try:
            return int(i)
        except ValueError:
            print("x is not an integer.")
        try:
            return int(float(i))
        except ValueError:
            print("x is not a float.")
        else:
            return x

main()

On line number 8 the input() will only accept text of type int. Therefore if you input a float it will throw a ValueError. But on line number 12 the input is being converted to a float then it is being converted to an int. Which does not throw a ValueError.
