Python TypeError: unsupported operand type(s) for |: 'str' and 'str' error

Hello when I try to make a basic input panel I encounter with that error.

TypeError: unsupported operand type(s) for |: ‘str’ and ‘str’

ip = str(input(">>> "))
if ip == "0" | ip == "00":
    pass
elif ip == "1" | ip == "01":
    send()
elif ip == "2" | ip == "02":
    st()
elif ip == "3" | ip == "03":
    fst()
elif ip == "4" | ip == "04":
    res

Just WHY???

>Solution :

| is the bitwise-or operator. From Operator precedence, | binds tighter than ==, so

ip == "0" | ip == "00"

could be expressed as

ip == ("0" | ip) == "00"

str doesn’t support bitwise-or, so the "0" | ip fails. You wanted logical or. Since or has lower precedence than ==, this works

ip == "0" or ip == "00"
