List items are indexed and you can access them by referring to the index number:
Print the second item of the list: thislist = ["apple", "banana", "cherry"]
print(thislist[1])The first item has index 0.
-1 refers to the last item, -2 refers to the second last item etc.
Print the last item of the list: thislist = ["apple", "banana", "cherry"]
print(thislist[-1])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: thislist = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(thislist[2:5])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 including, "kiwi": thislist = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(thislist[:4])By leaving out the end value, the range will go on to the end of the list:
This example returns the items from "cherry" to the end: thislist = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(thislist[2:])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 including "mango" (-1): thislist = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(thislist[-4:-1])To determine if a specified item is present in a list use the in keyword:
Check if "apple" is present in the list: thislist = ["apple", "banana", "cherry"] if "apple" in thislist:
print("Yes, 'apple' is in the fruits list")
