Python for Loop

For name in L:

For can iterate list and tuple

For loop
A list or tuple can represent an ordered set. What if we want to access each element of a list in turn? such as list:
L = [' Adam ', ' Lisa ', ' Bart ']
Print L[0]
Print L[1]
Print L[2]
If the list contains only a few elements, it is OK to write, and if the list contains 10,000 elements, we cannot write 10,000 lines of print.
This is where the loop comes in handy.
The python for loop can then iterate over each element of the list or tuple in turn:
L = [' Adam ', ' Lisa ', ' Bart ']
For name in L:
Print Name
Note: Name this variable is defined in the For loop, meaning that each element in the list is taken out, the element is assigned to name, and then the for loop body is executed (that is, the indented block of code).
This makes it very easy to traverse a list or tuple.
