Python nonlocal Keyword

❮ Python Keywords

Example

Make a function inside a function, which uses the variable x as a non local variable:

def myfunc1():
  x = "John"
  def myfunc2():
    nonlocal x
    x = "hello"
  myfunc2()
  return x

print(myfunc1())
Run example »

Definition and Usage

The nonlocal keyword is used to work with variables inside nested functions, where the variable should not belong to the inner function.

Use the keyword nonlocal to declare that the variable is not local.

More Examples

Example

Same example as above, but without the nonlocal keyword:

def myfunc1():
  x = "John"
  def myfunc2():
    x = "hello"
  myfunc2()
  return x

print(myfunc1())
