Python中有没有一种方法可以创建一个for循环，而不必等到内部代码完成后再进行迭代？

Question

假设我有一个for循环，里面有time.sleep函数

import time

list = [1, 2, 3]

for i in list:
    FunctionThatDoesSomethingTimeRelated(i)
    time.sleep(3)
    FunctionThatDoesSomethingTimeRelated(i)

有没有办法让循环同时遍历列表的每个部分，而不是等待循环中的代码被执行

基本上，执行顺序需要如下所示：

FunctionThatDoesSomethingTimeRelated(1)
FunctionThatDoesSomethingTimeRelated(2)
FunctionThatDoesSomethingTimeRelated(3)
time.sleep(3)
FunctionThatDoesSomethingTimeRelated(1)
FunctionThatDoesSomethingTimeRelated(2)
FunctionThatDoesSomethingTimeRelated(3)

与此相反：

FunctionThatDoesSomethingTimeRelated(1)
time.sleep(3)
FunctionThatDoesSomethingTimeRelated(1)
FunctionThatDoesSomethingTimeRelated(2)
time.sleep(3)
FunctionThatDoesSomethingTimeRelated(2)
FunctionThatDoesSomethingTimeRelated(3)
time.sleep(3)
FunctionThatDoesSomethingTimeRelated(3)

Answer 1

这就是你想做的吗

import time

list = [1, 2, 3]

for i in list:
    FunctionThatDoesSomethingTimeRelated(i)

time.sleep(3)

for i in list:    
    FunctionThatDoesSomethingTimeRelated(i)
