Question

a).Answer the question: where can you find the Standard Documentation for Python?

b)Write an algorithm for step 3.

c)Write a program that asks the user for a path to a directory, then updates the names of all the files in the directory that contain the word draft to instead say final

     EX: "term paper (draft).txt" would be renamed "term paper (final).txt"

BONUS (5pts): for any .txt file that your program changes the name of, have your program add a line of text that states "Edited on " followed by the current date to the end of the text in the file that it is editing.

Answer 1

a). The standard documentation can be found on their official website. A simple search in the search engine of your choice would show you the documentations.

c). I have used the "os" library to search and retrieve files in the directory and also to rename the files. "re" library is the regex library for python. I have used regex to find and replace the strings.

Below is the code with comments on every line:

Below are the files before the code execution:

Below are the files after the code execution:

Below is the screenshot of a file with edited date:

You can copy the code from here:

#CODE STARTS HERE-------------------------------------

import os   #Used to manipulate files in your os
import re  #Used to search and replace the strings in file name

dir_path=input("Enter the path to search\n") #Asking for user input

for root,dirs,files in os.walk(dir_path): 
   for file in files:
      if "draft" in file.lower(): 
         insensitive = re.compile(re.escape('draft'), re.IGNORECASE) 
         x=insensitive.sub('final',file) 
         src=os.path.join(dir_path,file) #preparing source path
         dest=os.path.join(dir_path,x)  #preparing destination path
         os.rename(src,dest)    #The file name is changed here

         #This adds the edited date inside the file
         import datetime
         dt_object = datetime.datetime.now()
         file_edit = open(dest, "a+")
         edit="EDITED ON "+str(dt_object)+"\n"
         file_edit.write(edit)
         file_edit.close()
