Negative Index in Python

Unlike other languages, Python does not throw an error when we try to access list elements with negative indexes.

For example, we can use the index -1 to select the last element of a list, even when we don’t know how many elements are in a list:

words = ["car", "egg", "plant", "flag"]

print(words[-1]) # Output: "flag"

In general, writing nums[-x] is equalivalent to writing nums[len(nums) - x]. We can access every element of a list using negative indexes:

words = ["car", "egg", "plant", "flag"]

print(myList[-1]) # Output: "flag"
print(myList[-2]) # Output: "plant"
print(myList[-3]) # Output: "egg"
print(myList[-4]) # Output: "car"
