'<' not supported between instances of 'int' and 'method'

This error message occurs when you try to use the comparison operator "<" between an integer and a method or function.

For example:

x = 5
def foo():
    return 10

if x < foo:
    print("x is less than foo")

In this code, we are trying to compare the integer value of `x` with the function `foo`. However, this is not allowed as `foo` is a method or function and cannot be compared in this way.

To fix this error, you need to make sure that you are comparing two values of the same data type. In this case, you could call the function `foo` to get its return value and compare it with `x`.

x = 5
def foo():
    return 10

if x < foo():
    print("x is less than foo")

Now, we are calling the function `foo` and comparing its return value with the integer value of `x`. This will produce the correct result without raising an error.
