It is possible to delete list elements with remove, pop, and clear functions and the del keyword. Python list removeThe remove function removes the first occurrence of the given value. It raises ValueError if the value is not present.
Here, we have first got the length of the list usinglen(my_list), and then usinglist_len - n, we have minus the number of elements we want to remove from the end of the list Next, we removed the last 2 elements from the list usingmy_list[:end_index]. Remove last n elements fr...
