Feb 19, 2025 · The cmp function was a built-in function in Python 2 for comparing the values of two objects. It has been removed in Python 3 and replaced with the == and is operators, which provide more robust and flexible comparison functionality.

As mentioned in the comments, cmp doesn't exist in Python 3. If you really want it, you could define it yourself: return (a > b) - (a < b) . which is taken from the original What's New In Python 3.0.

Dec 10, 2014 · from python wiki: In Py3.0, the cmp parameter was removed entirely (as part of a larger effort to simplify and unify the language, eliminating the conflict between rich comparisons and the __cmp__ methods).

cmp () returns the sign of the difference of two numbers. I don't really get what sign of the difference of two numbers means. Doesn't that mean that it returns a value when the sign of numbers aren't equal? Since... cmp(80, 100) : -1 # both have positive sign. cmp(180, 100) : 1 # both also have positive sign.

Apr 16, 2024 · The cmp() function in Python 3 is used to compare two objects and determine their relative order. It takes two arguments, let’s call them x and y, and returns an integer value based on the comparison result.

In this tutorial, we will learn how to use cmp () i.e compare function in Python. This function has different behaviour in different versions of Python. In Python version 2.x (x=1,2,3,…) we can directly use cmp () to compare any two entities of float, integer or string type.

Jan 5, 2025 · The cmp () function in Python compares two objects and returns their values. It was a built-in function in Python 2. However, in Python 3, it has been replaced by == and is operators, which make comparison objects more robust, accurate, and flexible and return negative and positive values, and zero occurs based on comparison values.

Oct 22, 2024 · The cmp() function in Python 2 provided a straightforward way to compare two values, but with its removal in Python 3, developers must adapt by using comparison operators or custom functions. Understanding these alternatives is …
