How do I check if a variable exists?

Question

I want to check if a variable exists. Now I'm doing something like this: try: myVar except NameError: # Do something.Are there other ways without exceptions?

Answer 1

You can use "locals()" and "globals()" to check if a variable exists locally or globally. For example:

if 'myVar' in locals():

# myVar exists locally

It's the same format for "globals()"
