*Memos:
enumerate() can create the iterable which has an iterable with the numbers incremented by 1 as shown below:
*Memos:
- The 1st argument is
iterable
(Required-Type:iterable
). - The 2nd argument is
start
(Optional-Default:0
-Type:int
). - The iterable cannot be directly accessed with index so use list() to access it with index.
