This will open up an IDLE Shell where it will output the code that you run. {“smallUrl”:“https://www. wikihow. com/images/2/21/IDLE. png”,“bigUrl”:"/images/thumb/2/21/IDLE. png/444px-IDLE. png",“smallWidth”:460,“smallHeight”:344,“bigWidth”:444,“bigHeight”:332,“licensing”:"<div class="mw-parser-output">

This will open a blank terminal where you can start typing your Python code. {“smallUrl”:“https://www. wikihow. com/images/thumb/9/98/Screen-Shot-2022-02-19-at-6. 48. 23-PM. png/460px-Screen-Shot-2022-02-19-at-6. 48. 23-PM. png”,“bigUrl”:"/images/thumb/9/98/Screen-Shot-2022-02-19-at-6. 48. 23-PM. png/510px-Screen-Shot-2022-02-19-at-6. 48. 23-PM. png",“smallWidth”:460,“smallHeight”:240,“bigWidth”:510,“bigHeight”:266,“licensing”:"<div class="mw-parser-output">

For this example, The example below will demonstrate taking each line from a previously created file and printing every other line (every odd line) onto a new file.

Use any variable you like (example: “oldfile”). Assign this to “open(“YOUR FILE NAME. txt”, ‘r’)”. {“smallUrl”:“https://www. wikihow. com/images/thumb/b/b1/Screen-Shot-2022-03-06-at-6. 18. 55-PM. png/460px-Screen-Shot-2022-03-06-at-6. 18. 55-PM. png”,“bigUrl”:"/images/thumb/b/b1/Screen-Shot-2022-03-06-at-6. 18. 55-PM. png/580px-Screen-Shot-2022-03-06-at-6. 18. 55-PM. png",“smallWidth”:460,“smallHeight”:24,“bigWidth”:580,“bigHeight”:30,“licensing”:"<div class="mw-parser-output">

\n</p></div>"} The letter “r” in this code stands for read.

Use any variable you like different from the first one (example: “newfile”) and assign it to “open(“NEW FILE NAME YOU ARE CREATING. txt”, ‘w’)”. {“smallUrl”:“https://www. wikihow. com/images/thumb/7/7c/Screen-Shot-2022-03-06-at-6. 19. 14-PM. png/460px-Screen-Shot-2022-03-06-at-6. 19. 14-PM. png”,“bigUrl”:"/images/thumb/7/7c/Screen-Shot-2022-03-06-at-6. 19. 14-PM. png/580px-Screen-Shot-2022-03-06-at-6. 19. 14-PM. png",“smallWidth”:460,“smallHeight”:22,“bigWidth”:580,“bigHeight”:28,“licensing”:"<div class="mw-parser-output">

Use any new variable (example: “eachline”) and assign it to your original file variable followed by “. readlines()”. {“smallUrl”:“https://www. wikihow. com/images/thumb/4/46/Screen-Shot-2022-03-06-at-6. 19. 33-PM. png/460px-Screen-Shot-2022-03-06-at-6. 19. 33-PM. png”,“bigUrl”:"/images/thumb/4/46/Screen-Shot-2022-03-06-at-6. 19. 33-PM. png/580px-Screen-Shot-2022-03-06-at-6. 19. 33-PM. png",“smallWidth”:460,“smallHeight”:22,“bigWidth”:580,“bigHeight”:28,“licensing”:"<div class="mw-parser-output">

The example contains a for loop that took the location of each line, decided if it was an odd line, and then used the new text file variable “. write(NAME OF FOR LOOP) to write every other line onto the new text file. {“smallUrl”:“https://www. wikihow. com/images/b/b3/Screen-Shot-2022-03-06-at-7. 16. 39-PM. png”,“bigUrl”:”/images/thumb/b/b3/Screen-Shot-2022-03-06-at-7. 16. 39-PM. png/426px-Screen-Shot-2022-03-06-at-7. 16. 39-PM. png",“smallWidth”:460,“smallHeight”:140,“bigWidth”:426,“bigHeight”:130,“licensing”:"<div class="mw-parser-output">

At the end of your code, write your text file variable “. close()”. Do this for each file that you previously opened in your code. {“smallUrl”:“https://www. wikihow. com/images/thumb/1/18/Screen-Shot-2022-03-06-at-6. 20. 03-PM. png/460px-Screen-Shot-2022-03-06-at-6. 20. 03-PM. png”,“bigUrl”:"/images/thumb/1/18/Screen-Shot-2022-03-06-at-6. 20. 03-PM. png/580px-Screen-Shot-2022-03-06-at-6. 20. 03-PM. png",“smallWidth”:460,“smallHeight”:46,“bigWidth”:580,“bigHeight”:58,“licensing”:"<div class="mw-parser-output">

This includes the file that your code is written on.

This is the final step that runs your program, Whatever files you wanted to write in should now be created after running this program. {“smallUrl”:“https://www. wikihow. com/images/thumb/7/73/Screen-Shot-2022-03-06-at-6. 41. 23-PM. png/460px-Screen-Shot-2022-03-06-at-6. 41. 23-PM. png”,“bigUrl”:"/images/thumb/7/73/Screen-Shot-2022-03-06-at-6. 41. 23-PM. png/728px-Screen-Shot-2022-03-06-at-6. 41. 23-PM. png",“smallWidth”:460,“smallHeight”:305,“bigWidth”:728,“bigHeight”:483,“licensing”:"<div class="mw-parser-output">
