Converting Strings to Operators in Python

It is possible to convert a string representing an operator, such as " " or "-", into the corresponding Python operator object. This can be achieved using a lookup table.

For instance, one can define a dictionary that maps strings representing operators to the corresponding operator functions:

import operator

ops = {"+": operator.add, "-": operator.sub, "*": operator.mul, "/": operator.truediv}

To use this lookup table, simply index it with the string representing the desired operator:

result = ops["+"](1, 1)  # Returns 2

This approach provides a convenient way to dynamically select and apply operators based on input strings.
