Python - Access List Items
List items are indexed and you can access them by referring to the index number:
Print the second item of the list:
Note: The first item has index 0.
Negative indexing means start from the end
-1 refers to the last item,
-2 refers to the second last item etc.
Print the last item of the list:
Range of Indexes
You can specify a range of indexes by specifying where to start and where to end the range.
When specifying a range, the return value will be a new list with the specified items.
Return the third, fourth, and fifth item:
Note: The search will start at index 2 (included) and end at index 5 (not included).
Remember that the first item has index 0.
By leaving out the start value, the range will start at the first item:
This example returns the items from the beginning to, but NOT included, "kiwi":
By leaving out the end value, the range will go on to the end of the list:
This example returns the items from "cherry" and to the end:
Range of Negative Indexes
Specify negative indexes if you want to start the search from the end of the list:
This example returns the items from "orange" (-4) to, but NOT included. "mango" (-1):
Check if Item Exists
To determine if a specified item is present in a list use the
Check if "apple" is present in the list:
if "apple" in thislist:
print("Yes, 'apple' is in the fruits list")
