...70t = 1071def test():72 global t73 t = 574 def test_nested():75 t = 376 print(t)77 test_nested()78 print(t)79test()80print(t)81Há 3 atribuições à variável *t* no código acima. Na função *test*, o operador **global** faz com que a atribuição *t = 5* seja aplicada à variável *t* global. Mas isso não afeta a atribuição *t = 3* da função aninhada *test_nested*. Para que a terceira atribuiçãose aplique à mesma variável, é necessário usar **global** novamente. 82t = 1083def test():84 global t85 t = 586 def test_nested():87 global t88 t = 389 print(t)90 test_nested()91 print(t)92test()93print(t)94O operador **global**, como seu nome indica, só se aplica a variáveis do escopo global. Se a variável *t* tivesse sido definida na função *test*, a função *test_nested* não poderia atribuir um valor a ela por meio do uso de **global**. Exemplo:95def test():96 t = 597 def test_nested():98 global t99 t = 3100 print(t)101 test_nested()102 print(t)103test()104print(t)105Note que no código acima, a linha **global** *t* dentro de *test_nested* cria uma nova variável global e não modifica a variável *t* criada por *test*. Caso deseje-se modificar o valor da variável *t* definida no escopo acima, usa-se o operador **nonlocal**:106def test():107 t = 5108 def test_nested():109 nonlocal t110 t = 3111 print(t)112 test_nested()113 print(t)114test()115Outro exemplo, retirado da [documentação de Python](https:/​/​fanyv88.com:443/​https/​docs.python.org/​3/​tutorial/​classes.html).116def scope_test():117 def do_local():118 spam = "local spam"119 def do_nonlocal():120 nonlocal spam121 spam = "nonlocal spam"122 def do_global():123 global spam124 spam = "global spam"125 spam = "test spam"126 do_local()...
