Use A String (representing A Logical Operator) In A Python Expression

Is it possible to somehow cast a string of, say, or or and into a form that is recognizable as a logical operator? For example, is it possible to do something like this: l = [1, 2,

Solution 1:

You may use the operator package:

importoperator

o = {item1: operator.or_}

if o[item1](i>4, i<0):
    ...

Note that or_ does not short-circuit, like or does. If you really need the short-circuit behaviour, you can use eval (but this is in general not recommended).
