How to Write Custom Sort Functions in Python - LearnPython.com

Let’s discover how to use custom sort functions to implement custom orders and comparisons in Python. In my previous article on working with streams in Python, I briefly introduced sorting methods with list.sort () and sorted ().

Passing functions as arguments to other functions - Python Morsels

In Python you can pass a function to another function as an argument. We have a list of strings represent fruit names: If we wanted to alphabetize this list we could pass it to the built-in sorted function:

operator — Standard operators as functions - Python

Perform “rich comparisons” between a and b. Specifically, lt(a, b) is equivalent to a < b, le(a, b) is equivalent to a <= b, eq(a, b) is equivalent to a == b, ne(a, b) is equivalent to a != b, gt(a, b) is equivalent to a > b and ge(a, b) is equivalent to a >= b.

python - Is it possible to pass comparison operators as parameters into ...

Yes, you can use methods from the operator library if you want to use the comparision operator as a parameter to a function -- in this case, you're looking for operator.ge: if b(a, 0): print('...') Same could be done with a lambda function. But your solution is way more clear. BrokenBenchmark is right, passing a function is the way to achieve this.

python - Passing a comparison operator with a value into a function ...

If you want to pass both a comparison operator and its value as one argument you have several options: return condition(1) return 2 > x. Applying any of these approaches to your function with several arguments should be trivial. I am defining a function where one parameter should be a comparison operator.

python - How do comparison operators < and > work with a function as an ...

My understanding is that E > F is equivalent to (E).__gt__(F) and for well behaved classes (such as builtins) equivalent to (F).__lt__(E). If there's no __lt__ or __gt__ operators then I think Python uses __cmp__. But, none of these methods work with function objects while the < and > operators do work.

Pass by reference vs value in Python - GeeksforGeeks

Python's argument-passing model is neither "Pass by Value" nor "Pass by Reference" but it is "Pass by Object Reference". Depending on the type of object you pass in the function, the function behaves differently. Immutable objects show "pass by value" whereas mutable objects show "pass by reference".
