Python 3 嵌套 IF 语句

Python 3 条件语句

可能会出现在条件解析为真后您想检查另一个条件的情况。在这种情况下，您可以使用嵌套的if 结构。在嵌套if结构中，你可以有一个，IF... ELIF ...ELSE 构造里面写另一个 IF... ELIF...ELSE 结构。

语法

嵌套的if...elif...else构造的语法可能是

if expression1:
   statement(s)
   if expression2:
      statement(s)
   elif expression3:
      statement(s)
   elif expression4:
      statement(s)
   else:
      statement(s)
else:
   statement(s)

示例

# !/usr/bin/python3

num = int(input("enter number"))
if num%2 == 0:
   if num%3 == 0:
      print ("Divisible by 3 and 2")
   else:
      print ("divisible by 2 not divisible by 3")
else:
   if num%3 == 0:
      print ("divisible by 3 not divisible by 2")
   else:
      print  ("not Divisible by 2 not divisible by 3")

执行上述代码时，结果如下：

enter number8
divisible by 2 not divisible by 3

enter number15
divisible by 3 not divisible by 2

enter number12
Divisible by 3 and 2

enter number5
not Divisible by 2 not divisible by 3
