一、列表推导式

指轻量级循环创建列表

1.1 基本方式

my_list = [x for x in range(10)]
print(my_list)

结果：[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

my_list = [x for x in ["haha"]*5]
print(my_list)

结果：['haha', 'haha', 'haha', 'haha', 'haha']

my_list = ["hello" for x in range(5)]
print(my_list)

结果：['hello', 'hello', 'hello', 'hello', 'hello']

1.2 循环的过程中使用if

my_list = [x for x in range(10) if x % 2 == 0]
print(my_list)

结果：[0, 2, 4, 6, 8]
