How to Convert a String Representation of an Operator into its Corresponding Function?

String to Operator Conversion

Question:

Transform a string representation of an operator (e.g., " ") into the actual operator function itself (e.g., the addition operator).

Answer:

Employ a lookup table to establish a mapping between operator strings and their corresponding function implementations.

Code:

import operator

ops = {"+": operator.add, "-": operator.sub}  # Customize as needed

result = ops["+"](1, 1)  # Applies the addition operator
print(result)  # Outputs 2
Copy after login

This approach efficiently translates strings representing operators into their respective functional counterparts, enabling runtime flexibility in executing operations based on string inputs.
