declare a global variable in python

global_variable = "This is a global variable"

This code creates a global variable called “global_variable” and assigns it the value of the string “This is a global variable”. A global variable is a variable that can be accessed anywhere in the code, including functions and classes. When a global variable is declared, it can be used and modified throughout the entirety of the code. In Python, global variables are declared outside of all functions and classes, so any code that is not in these structures can access and modify them. In this example, the global variable “global_variable” is assigned the value of the string “This is a global variable”, so that it can be accessed and modified in the rest of the code.
