python - 复合 if elif else 语句 + python

Question

我正在尝试从复合/嵌套 if/elif/else 语句中传递一个项目。

if x == 0:
    do something
elif x == 1:
    do something else
elif x == 2:
    if x == 2 and x == whatever:
        do something
    elif x == 2 and x == whatever:
        do something
    else:
        pass it back out
elif x = 3:
    do something
else:
    do something

我如何将它从内部 if 传回，以便检查它是否等于 3？

pass 语句在这里有效吗？ continue 不断抛出错误。

Answer 1

if x == 0:
    do something
elif x == 1:
    do something else
elif x == 2 and y == whatever:
        do something
elif x == 2 and y == whatever:
        do something

elif x = 3:
    do something
else:
    do something

也许？如果您已经输入了 if/elif 分支，则无法输入新的 if/elif 分支

另一个选择是将其余部分移到里面

if x == 0:
    do something
elif x == 1:
    do something else
elif x >= 2:
    if x == 2 and x == whatever:
        do something
    elif x == 2 and x == whatever:
        do something
    elif x = 3:
        do something
    else:
        do something

另一个选项是遵循其他示例并开始一个新的 if block ，尽管您需要小心一点，不要检查其他分支之一可能更改的条件...并且每个选项都必须是互斥的其他选项
