How Can I Dynamically Set Local Variables in Python?

Dynamically Setting Local Variables in Python

Contrary to some suggestions, modifying locals() directly in Python will not grant you the desired flexibility with local variables. While it may appear to work in certain situations, this approach is inherently unreliable.

Alternatives to locals() Modification:

Instead, consider using one of the following methods to dynamically set local variables:

  • Dictionaries: Create a dictionary and assign the variable name as the key and the desired value as the associated value. For example:
d = {}
d['xyz'] = 42
print(d['xyz'])  # Output: 42
Copy after login
  • Class Attributes: Instantiate a class object and set the attribute name dynamically using the setattr() function. For example:
class C: pass

obj = C()
setattr(obj, 'xyz', 42)
print(obj.xyz)  # Output: 42
Copy after login

These alternative methods provide a reliable and consistent approach to dynamically setting local variables in Python.
