How to check if a variable exists in Python
You can easily check if a variable exists in Python in either local or global scope.
To check if a variable exists in the global scope, verify the name of the variable as a string between quotes and use the in operator using the globals() function.
To check if a variable exists in the local scope, you also verify the name of the variable as a string and check it against the locals() function.
