global

The global keyword creates or references a global variable that can be updated within the scope of a function or class.

variable = initial_value

def function_name:
  global variable
  # ...

class ClassName:
  global variable

  def example_method:
    global variable
    # ...

The snippet above showcases the various places that a variable can be referenced with the global keyword.

Note: The variable must not be defined and set within the function/class scope before being referenced with the global keyword. Otherwise, an error will occur.
