How to make input verification in a separate function? the program should take the input sequence 1 and 0

def check(SEQ):
    for i in SEQ:
        isinstance(i, int)
    if not (set(SEQ) == {0, 1} or set(SEQ) == {1} or set(SEQ) == {0}):
        return False
    else:
        return True


def main():
    SEQ = [i for i in input("Enter the sequence 0 and 1   ").split()]
    while not check(SEQ):
        print("Invalid values ")
        SEQ = [i for i in input("Enter the sequence 0 and 1 ").split()]


if __name__ == '__main__':
    main()

Like this:

def check(value):
    return all(map(lambda x: x=='1' or x=='0', value.split()))
