Question

***This program is to be created using PyCharm Pro***

1. Print “This program manipulates text from files and the clipboard and performs other string, file, and directory manipulation tasks.”

2. Output the current working directory of the program.

3. Ask the user to enter the directory where they would like files to be stored, make that directory, and store files in the program in that directory.

4. Write the following three lines to file_one.txt (without bullet points):
• Line 1 from file_one wrong_text
  • Line 2 from file_ one wrong_text
  • Line 3 from file_ one wrong_text

5. Display the contents of file_one.txt.

6. Programmatically replace the substring ‘file_one wrong_text’ in data read from file_one.txt with ‘file_two correct_text’ and write the corrected lines to file_two.txt.

7. Ask the user to type the following lines (without bullet points) into Notepad++ and copy the lines to the clipboard (using Ctrl-c): • Line 1 from the clipboard • Line 2 from the clipboard • Line 3 from the clipboard

8. Programmatically display the contents of the clipboard which should contain the three lines from Requirement 7.

9. Read the contents of file_two.txt and read the contents of the clipboard.

10. Append the contents of the clipboard onto the contents of file_two.txt line-by-line to produce the following:
  • Line 1 from file_two correct_text followed by Line 1 from the clipboard
• Line 2 from file_two correct_text followed by Line 2 from the clipboard
• Line 3 from file_two correct_text followed by Line 2 from the clipboard

11. While performing Requirement 11, write the lines out to file_three.txt.

12. Display the contents of the file_three.txt.

13. Ask the user for a new directory name. Programmatically create that directory and programmatically copy the files created earlier in the program to the new directory. Programmatically compress the files in the new directory.

Code:

import os
import clipboard #install this module to work with clipboard
#type 'pip install clipboard' in cmd to do that
import shutil
#shutil is used to copy files
import zipfile
#zip file is used to work with zipfiles

#1
print("This program manipulates text from files and the clipboard and performs other string, file, and directory manipulation tasks")

#2 current working directory
currDir = os.getcwd()#getting the current working directory
print("Current working directory: ",currDir)

#3
makeDir=input("Enter Directory name to store files: ")
#if the directory already exists
#we need not to create that directory
#else we have to create that directory

#changing the directory

#4
#opening the file with write mode

file_one.close()

#5,6

for i in file_one:

#writing the replced text to file_two

#closing the files

#11

file_three.close()

#12

for file in files:
#name of the new zip file

#creating a zip file and writing the data of current file
z= zipfile.ZipFile(filename, 'w')
#compress_type=zipfile.ZIP_DEFLATED will compress the file as zip
