Answer:
def prolog(mylist):
for x in range(2):
del mylist[0]
del mylist[-1]
return mylist
scores = [23, 23,45, 45, 65, 65]
result = prolog(scores)
Explanation:
The del keyword in python is used to delete variable and items in a data structure like in a list. To delete a list, specify the list name and also an index to delete an item.
The function 'prolog' loops through a list to delete the first and the last two items.
The program deleted the firsts and last two elements in a list. The program is written in python 3 and it goes thus :
def prolog(word_list):
#initialize a function named prolog that takes a list of strings as an argument.
for letter in range(2):
#iterate twice over the list:
del word_list[0]
#delete the first word for each iteration
del word_list[-1]
#delete the last word for each iteration
return word_list
#return the list
words = ['a','b', 'c', 'd' , 'e']
A sample run of the program is attached.
print(prolog(words))
