Question

if a not in list and a == b:
    //add to list
    //do stuff in For Loop
    return True  
elif a in list and not a == b:
    //add to session
    //do stuff in For Loop
    return True
elif a in list and a == b:
    //do stuff in For Loop
    return True
elif a not in list
    //add to list
    //add to session
    return True        
else:
   return

For循环中的// do东西是在3个if语句中重复的相同代码

Answer 1

我建议您采用我的解决方案，将动作“添加到列表” ，“添加到会话” 和“执行任务” 与原始代码的顺序相同。我还考虑过可以将这些动作替换为示例中的print()语句，如下所示：

def func():
    if a not in a_list:
        print("add to list")

    if a != b:
        print("add to session")

    if (a == b) or (a in a_list):
        print("do stuff")

    return True

注意：在python中，注释行以＃字符开头，而不是//

Answer 2

if a in lst or a == b:
    # Do stuff

if a != b :
    # add to session

if a not in lst :  # have to be at the end since it modify the list
    # add to lst

return True

重构if语句
