Question

1)  Write a python program that opens a file, reads all of the lines into a list of strings, and closes the file. Use the Readlines() method. Test your programing using the names.txt file provided.
2) Convert the program into a function called loadFile, that receives the file name as a parameter and returns a list of strings.
3) Write a main routine that calls loadFIle three times to load the three data files given into three lists. Then choose a random element from the title list, two from the name list, and one from the descriptor list to generate a name. Print the name be in the form shown (you have to add the "the"):
title name name the descriptor
For example:
King Ludovicus Botolf the Bowman
Print the name to the screen.   
Submit your python file (.py) to Sakai

Part 2: Writing Files (Optional Extra Credit 20 pts)
Modify the program to generate 10 names and store them in a list.
Write a function, dumpFile that writes the list to a file called "CharacterNames.txt" There should be one Character Name on each line in the file.
Test the program to be sure it works

Im stumped at number 2

here is what i have for number 1

f = open('names.txt', 'r')
lines = f.readlines()
for line in range(len(lines)):
lines[line] = lines[line].rstrip()
print(lines)
f.close()

Answer 1

Part 1:

1)

Python program that reads all the lines of a file into a list of strings and closes the file.

Program:

lines=[]

# Store each line in a list

with open('input.txt') as file:

    lines = file.readlines()

# Remove new line in each string

lines = [i.strip() for i in lines]

file.close()

for i in lines:

    print(i)

Input text file (input.txt):

Jack

Micheal

Alex

Bob

Sample output:

2)

The loadFile function receives the file name as a parameter and returns a list of strings.

Program:

def loadFile(fileName):

    lines=[]

    with open(fileName) as file:

        lines = file.readlines()

    lines = [i.strip() for i in lines]

    file.close()

    return lines

lines=loadFile('input.txt')

print (lines)

Input text file (input.txt):

Jack

Micheal

Alex

Bob

Sample output:

3)

The complete program along with main function.

Program:

import random

def loadFile(fileName):

    lines=[]

    with open(fileName) as file:

        lines = file.readlines()

    lines = [i.strip() for i in lines]

    file.close()

    return lines

def main():

    # Call the loadFile function along with the text document as parameter

    title=loadFile('title.txt')

    name=loadFile('name.txt')

    descriptor=loadFile('descriptor.txt')

    # Generate random strings

    rand_title=title[random.randint(0,len(title)-1)]    

    rand_name1=name[random.randint(0,len(name)-1)]   

    rand_name2=name[random.randint(0,len(name)-1)]

    rand_desc=descriptor[random.randint(0,len(descriptor)-1)]

    # Print the output

    print(rand_title+" "+rand_name1+" "+rand_name2+" the "+rand_desc)

       

main()

Input text files:
