In this article, we will explore how to update and delete elements in a list in Python. We will cover methods to update elements by index and delete elements using different functions.
Updating Elements in a List
To update elements in a list, you can simply assign a new value to the desired index in the list.
l = [1, 2, 3, 4]
l[1] = 11
print(l)
Deleting Elements from a List
There are multiple functions available in Python to delete elements from a list:
remove
