Answer :-

(i)

lst = eval(input("Enter a list of string = "))
if lst == [] :
    print("List should contain at least one element ")
else :
    long = ""
    for i in range(len(lst)) :
        if len(long ) < len(lst[i]) :
            long = lst[i]
    print("Longest string in list = ",long)

(ii)

lst = eval(input("Enter a list = "))
num = int(input("Enter a number = "))
for i in range(len(lst)):
    lst[i] = lst[i] + num
print("New list = ",lst)

Output :-

(i)

Enter a list of string = ["Path","Walla","Portal","Express"]
Longest string in list =  Express
>>>

Enter a list of string = []
List should contain at least one element
>>>

(ii)

Enter a list = [1,2,3,4,5,6,7,8,9]
Enter a number = 5
New list =  [6, 7, 8, 9, 10, 11, 12, 13, 14]
>>>

Enter a list = [78,54,2,9,4,6,3,84,21,74]
Enter a number = 9
New list =  [87, 63, 11, 18, 13, 15, 12, 93, 30, 83]
>>>
