Lpthw stupid way to learn Python chapter 33

The 32-33 chapters will be for-loop and while-loop loops.

The two kinds of syntax will not be said. Simply say the individual's understanding for and while.

I think he learn python.

First say the same point:

1, can not do a single operation, For-loop if the collection is empty, the condition behind the while is false he can also do a loop operation is not done, the test method is as follows:

　　

 for inch  []:     Print " 1 " , I,    

　

　　

 While I <=2:    Print 1,    + = 1    

2, the difference is that For-loop objects can be iterated, that is, you can read something in the body of the loop.

The loop control of the While-loop is a Boolean control that can be cycled as long as a Boolean value is finally fed back.
