Converting Kwargs Into Variables?

How do I convert kwargs objects into local variables? I am a math teacher and I want to write a helper function where I can use JS-style template strings to write problems. I want

Solution 1:

If you're planning to use eval, you don't need to convert them to locals at all. eval takes optional globals and/or locals arguments that defines the active scope variables for that expression. If you provide globals (the second positional argument) and not locals (the third), then globals is reused as locals, so for example:

>>> eval('a * b', {'a': 5, 'b': 3})
