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.

1 day ago · 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.

When the pass statement is executed, nothing happens, but you avoid getting an error when empty code is not allowed. Empty code is not allowed in loops, function definitions, class definitions, or in if statements. Using the pass keyword in a function definition: Using the pass keyword in a class definition:

Jun 22, 2013 · To run it, you could define a function like this: return n * n. And then pass it to your other function: You can also use lambda to avoid having to define a new function if it's a simple expression: That takes care of functions, but how can I also incorporate arithmetic (as in the e example I gave)?

In your perform_operation() function, the first parameter is a string representing one of the four basic arithmetic operations. To test the function, you pass in each of the four operators. The results are what you’d expect: This code is not only messy, but also limited to the four operators defined in the elif clauses.

In Python, the pass keyword is an entire statement in itself. This statement doesn’t do anything: it’s discarded during the byte-compile phase. But for a statement that does nothing, the Python pass statement is surprisingly useful. Sometimes pass …

Jan 4, 2025 · In a conditional statement (like an if, elif or else block), the pass statement is used when we don’t want to execute any action for a particular condition. Explanation: When x > 5, the pass statement is executed, meaning nothing happens. If x …

Apr 3, 2022 · 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.

Mar 11, 2024 · For instance, you might want to perform an operation on a list of elements or pass an operator as an argument. The desire is to transform operators into callable functions that can be utilized wherever a first-class function can be. The Python operator module provides function equivalents for many built-in operators.

1 day ago · The operator not in is defined to have the inverse truth value of in. 6.10.3. Identity comparisons¶ The operators is and is not test for an object’s identity: x is y is true if and only if x and y are the same object. An Object’s identity is determined using the id() function. x is not y yields the inverse truth value. [4] 6.11.
