Question

Write a function called format_name that accepts a string in the format of first name followed by last name as a parameter, and then returns a string in reverse order (i.e., last name, first name). You may assume that only a first and last name will be given.

For example, format_name("Jared Smith") should return "Smith, Jared"

Hint: The following String Methods will be useful:

# Returns the lowest index in the string where substring is
# found. Returns -1 if substring is not found
my_string = “eggplant”
index = my_string.find(“plant”)      # returns 3

# Returns all the characters after the specific index
my_string = "hello world!"
print my_string[1:] # returns "ello world!"
print my_string[6:] # returns "world!"

# Returns all the characters before the specific index
my_string = "hello world!"
print my_string[:6] # returns "hello"
print my_string[:1] # returns "h"

Your program should include:

• A main method that uses user input to prompt and read a string that contains a person's first name and last name
• A call to format_name and a print statement that prints the output returned by format_name
• A call to the main function

Answer 1

The following code has been written in Python 3. For testing purpose, we have considered the same example name and shown the output after executing the code

Source code:

# Following function returns the formatted name

def format_name(name):

first_name, last_name = name.split()

formatted_name = last_name + ", " + first_name

return formatted_name

# Main function

def main():

name = input("Enter the person's name: ")

print("The formatted name is: %s" % format_name(name))

if __name__ == "__main__":

main()

Picture of source code along with sample input and sample output:

As you can see output in the above terminal

1 2 3 4 5 6 7 8 9 10 . Following function returns the formatted name def format_name(name): first name, last name = name.split() formatted_name = last_name + " + first_name return formatted_name # Main function def main(): name = raw_input("Enter the person's name: ") print "The formatted name is: ** $ format_name(name) if 12 13 name main() 15 PROBLEMS OUTPUT DEBUG CONSOLE TERMINAL Enter the person's name: Jared Smith The formatted name is: Smith, Jared
