Answer to Question #251662 in Python for Isabel Cortez

Question

Activity #5 – Applying Functions The output of this activity will be the same as activity #3 but instead you are required to use a function for the following algorithm:

1. A function for getting the length of each string

2. A function to get the shortest string

3. And a function to get the longest string Assume that each string has its own unique length.

Sample Run:

Sample Run A

Enter value of X: 3

Enter string value: a

Enter string value: ab

Enter string value: abc

a - total length is 1

ab - total length is 2

abc - total length is 3

The shortest string is a

The longest string is abc

Sample Run B

Enter value of X: 4

Enter string value: chico

Enter string value: strawberry

Enter string value: banana

Enter string value: guyabano

chico - total length is 5

strawberry - total length is 10

banana - total length is 6

guyabano - total length is 8

The shortest string is chico

The longest string is strawberry

Answer 1

CODE FOR THE QUESTION

#A function for getting the length of a string
def string_length(my_string):
    return len(my_string)

#A function to get the longest string
def shortest_string(my_length_list, my_strings_list):
    shortest_lengthr = my_length_list[0]
    index_for_shortest = 0;
    for element in my_length_list:
        if element < shortest_lengthr:
            shortest_lengthr = element
            index_for_shortest = my_length_list.index(element)

    return my_strings_list[index_for_shortest]

#A function to get the longest string
def longest_string(my_length_list, my_strings_list):
    longest_length = my_length_list[0]
    index_for_longest = 0;
    for element in my_length_list:
        if element > longest_length:
            longest_length = element
            index_for_longest = my_length_list.index(element)

    return my_strings_list[index_for_longest]

#Prompt the user to enter the number of strings
x = int(input("Enter value of X: "))

#Declare a list to store the strings
my_string_list = []
#Declare a list to store the lengths of the strings
my_string_list_lengths = []
#Prompt the user to enter all the strings
for i in range(0,x):
    my_string = input("Enter string value ")
    my_string_list.append(my_string)
    #append the length to the length list
    my_string_length = string_length(my_string)
    my_string_list_lengths.append(int(my_string_length))

#Print all the strings with their length
for element in my_string_list:
    print(element+" - Total length is "+str(string_length(element)))

print("\nThe shortest string is "+shortest_string(my_string_list_lengths,my_string_list))
print("The longest string is "+longest_string(my_string_list_lengths,my_string_list))
