Python PEP-8：E122 和 E501 之后的分配

Question

在如下情况下，如何改进多变量或长变量的赋值以遵循规则E122和E501：

def my_example_function():
    return 1, 2, 3, 4
# How can I improve the following line:
first_variable, second_variable, third_variable, fourth_variable = my_example_function()

Answer 1

只需跨越多行..

( first_variable, second_variable, 
  third_variable, fourth_variable ) = my_example_function()

Answer 2

E122 says the line should be less than 80 characters, and E501 says that continuation lines should be indented. 重写该行的常用方法是，

first_variable, second_variable, third_variable, fourth_variable = \   
    my_example_function()
