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 ().

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: Comparison in function argument - Stack Overflow

You could pass functions that implement the desired comparison - lambda: A==B for example - and call them at the desired moment in time. what kind of comparison is <=> ? You'd need to return some object from F.col() that implements __eq__, and returns some custom object from that __eq__ which you can then pick apart in your function.

python - Use comparison statement as parameter in function to then pass ...

Maybe by passing a comparison function and the desired parameters? Something like this: (assuming your second condition is something like x <= y) This creates two lambda (for simplification) functions that perform the desired comparison with the parameters x and y. Then you create your function as: while comparison(start, limit): start += 1.

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".

Operator Functions In Python - Flexiple

Comparison operators in Python can be utilized as functions using the operator module, enabling a functional approach to comparing values. This is particularly useful in scenarios where you need to pass a comparison operation as a function argument or in functional programming paradigms.

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.
