  return something

Local and Global scope (Namespaces)

Global

variable_global = 5

Local

def game():
  variable_local = 5

Modify global variables inside a function (not recommended has it could lead to bugs in the code)

variable = 0

def game():
  global variable
  variable += 1
 
game()
print(variable) # Output should be 1

Both variables are the same name but different scopes

enemies = 1

def increase_enemies():
  enemies = 2
  print(f"enemies inside function: {enemies}")

increase_enemies()
print(f"enemies outside function: {enemies}"))

enemies = 1

def increase_enemies():
  enemies = 2
  print(f"enemies inside function: {enemies}")
  return enemies - 1

increase_enemies()
print(f"enemies outside function: {enemies}"))
