Answer 1

Part 1

string="arjun nimmy peter nishal rahul varsha sonu namitha sebastian minnu krishnapria"#string consisting of a long series of words

print(string)

list1=string.split()#converting string to list

print(list1)

list1.remove("arjun")#deleting from list

print(list1)

list1.pop(-1)#deleting from list

print(list1)

del list1[1]#deleting from list

print(list1)

list1.sort()#sorting the list

print(list1)

list1.append("meera")#inserting to list

print(list1)

list1.insert(5,"bhavana")#inserting to list

print(list1)

list1.extend(["reena"])#inserting to list

print(list1)

list2=" ".join(list1)#converting list to string

print(list2)#printing the converted string

Part 2

list1=["arjun","nimmy",["reena","minnu"]]#example of nested list

print(list1)

list2=["arjun"]*2# * operator usage

print(list2)

list3=list2[0:1]#slicing operator usage

print(list3)

list2+=["nimmy"]# += operator usage

print(list2)

list4=[True,True,False,False]

list5=list(filter(None,list4))#usage of filter

print(list5)

list6=["arjun"]

list6=list6.append("nimmy")#legal list operation but does the wrong thing, instead of adding "nimmy" to the list, it will produce result as None

print(list6)
