一个函数不能在调用它的代码中引起中断或继续.中断/继续必须从字面上出现在循环内.您的选择是:

1. 从funcA返回一个值，并用它来决定是否破坏
2. 在funcA中引发异常并将其捕获在调用代码中(或调用链中更高的位置)
3. 编写一个生成器，该生成器封装中断逻辑，然后在range
上对其进行迭代

通过#3，我的意思是这样的:

def gen(base):
    for item in base:
        if item%3 == 0:
           break
        yield i

for i in gen(range(1, 100)):
    print "Pass," i

这允许您通过将条件分组到基于基本"迭代器(在此情况下为范围)的生成器中来放置条件.然后，您在此生成器上进行迭代，而不是在范围本身上进行迭代，您会得到破坏行为.

def funcA(i):
   if i%3==0:
      print "Oh! No!",
      print i
      break

for i in range(100):
   funcA(i)
   print "Pass",
   print i

I know script above won't work. So, how can I write if I need put a function with break or continue into a loop?

A function cannot cause a break or continue in the code from which it is called. The break/continue has to appear literally inside the loop. Your options are:

1. return a value from funcA and use it to decide whether to break
2. raise an exception in funcA and catch it in the calling code (or somewhere higher up the call chain)
3. write a generator that encapsulates the break logic and iterate over that instead over the range

By #3 I mean something like this:

def gen(base):
    for item in base:
        if item%3 == 0:
           break
        yield i

for i in gen(range(1, 100)):
    print "Pass," i

This allows you to put the break with the condition by grouping them into a generator based on the "base" iterator (in this case a range). You then iterate over this generator instead of over the range itself and you get the breaking behavior.
