How to Retrieve a Variable's Value Using its String Name in Python?

Dynamic Variable Value Retrieval in Python

In Python, a common challenge arises when attempting to access the value of a variable when its name is stored as a string. This query explores how to achieve this functionality in Python, inspired by a similar PHP approach.

One possible solution is to leverage the globals() function, which returns a dictionary containing all global variables. By accessing the variable name from this dictionary, one can retrieve the variable's value.

a = 5
globals()['a']  # Output: 5

It is important to note that this method assumes the variable is defined within the global scope. If the variable resides in a different namespace, accessing its value requires obtaining access to that specific namespace.
