Python path-iterators and generators

Wedge

Suppose there is now a list of L = [' A ', ' B ', ' C ', ' d ', ' e '], and there are several ways to take the contents of the list

First, the index can be evaluated by l[0], followed by a for loop to take the value

Thinking: There is a subtle difference between using an index and a for loop to take a value.

If you use an index to take a value, you can take the value anywhere, but only if you know where the value is.

If you use a for loop to take a value, take each value, you do not need to care about the location of each value, because only the order of the value, and can not skip any one value, directly to the value of other locations.

But have you ever wondered why we can use a for loop to take a value?

How does the For loop work inside?
