operator — Standard operators as functions — Python 3.13.3 documentation
The operator module provides efficient functions that correspond to the intrinsic operators of Python, such as operator.add(x, y) for x+y. Learn how to use these functions for object comparisons, logical operations, mathematical operations, sequence operations, and callables.

How to pass an operator to a python function? - Stack Overflow
Use the operator module. It contains all the standard operators that you can use in python. Then use the operator as a functions: return op(inp, cut): If you really want to use strings as operators, then create a dictionary mapping from string to operator function as @alecxe suggested.

Working With the Python operator Module
In this section, you’ll learn about the operator module’s operator-equivalent functions that mimic built-in operators, and you’ll pass them as arguments to higher-order functions. You’ll also learn how to save them for later use.

The operator Module in Python: itemgetter, attrgetter, methodcaller
In Python, the operator module provides functions for the built-in operators and functions to create callable objects that fetch items, attributes, and call methods. operator.itemgetter(), operator.attrgetter(), and operator.methodcaller() are often used for the key argument in functions like sorted(). See the following article for details.

Python Functions - W3Schools
To call a function, use the function name followed by parenthesis: Information can be passed into functions as arguments. Arguments are specified after the function name, inside the parentheses. You can add as many arguments as you want, just separate them with a comma. The following example has a function with one argument (fname).

Operator and Function Overloading in Custom Python Classes
Every class in Python defines its own behavior for built-in functions and methods. When you pass an instance of some class to a built-in function or use an operator on the instance, it is actually equivalent to calling a special method with relevant arguments.

Operator Overloading in Python - GeeksforGeeks
Operator Overloading means giving extended meaning beyond their predefined operational meaning. For example operator + is used to add two integers as well as join two strings and merge two lists. It is achievable because '+' operator is overloaded by int class and str class.

10.3. operator — Standard operators as functions - Python 3.7 Documentation
The operator module exports a set of efficient functions corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. Many function names are those used for special methods, without the double underscores.

6. Expressions — Python 3.13.3 documentation
When a description of an arithmetic operator below uses the phrase “the numeric arguments are converted to a common type”, this means that the operator implementation for built-in types works as follows: otherwise, both must be integers and no conversion is necessary.

Operator Functions In Python - Flexiple
Operator functions are essentially function equivalents of Python's standard operators. They are found in the operator module, which needs to be imported before use. These functions include, but are not limited to, arithmetic, comparison, and logical operations. Why Use Operator Functions?
