为什么这个“ else”块可以工作，但与“ if”情况不在同一个级别？ [英] Why does this `else` block work yet it is not on the same level as the `if` case?

问题描述

此代码运行得很好，并生成所需的质数列表。但是打印我们素数的 else 块是块状的，但是不管怎么说，有人可以向我解释吗？

This code runs pretty well and generates the wanted list of prime numbers. But the else block that prints our prime numbers is out of block, but it works anyway, can someone explain it to me?

for num in range(0, 100 + 1):
   # prime numbers are greater than 1
   if num > 1:
       for i in range(2, num):
           if (num % i) == 0:
               break
       else:
           print(num)

推荐答案

Python整洁 for-else 构造：

Python has a neat for-else construct:

For循环中还有一个else子句，我们大多数人都不熟悉。 else子句在循环正常完成时执行。这意味着循环没有遇到任何中断。

For loops also have an else clause which most of us are unfamiliar with. The else clause executes when the loop completes normally. This means that the loop did not encounter any break.
