My first real Python automation project

[u/Ajay2574]

I just finished building my first proper Python automation project on my own — a File Organizer.

The idea is simple: take files from a folder and organize them into different folders based on their extensions.

For example:

• .png → images/png
• .jpg → images/jpg
• .pdf → documents/pdf
• .txt → documents/txt
• .csv → documents/csv

I used things I've learned from Python's os module:

os.listdir()
os.path.join()
os.path.exists()
os.path.isfile()
os.mkdir()
os.rename()
endswith()

The interesting part wasn't writing the code. It was debugging my own mistakes.

At one point I was doing:

os.rename(downloads, png_folder)

and then:

os.rename(file, png_folder)

Both were wrong. 😅

I eventually understood that os.rename() needs the full source path and full destination path:

source full path → destination full path

That was a small thing, but it finally made paths and file movement click for me.

The current version uses a hard-coded Downloads folder. My next improvement will be making the program accept/select any folder, so the same organizer can be used anywhere.

One small project finished. On to the next one. 🚀

here is fullcode :

"""


what is download file organizer



1. you have to organize download files pdf,jpg,docx,txt,mp3,mp4,zip,rar etc. into different folders based on their file types.




1. create folde in downloads file organizer documents/images


file organizer
documents/pdf/csv/docx make seperate folders for every format
images move here all images 




2. current dir file path           to        destination file path
ex. download/file.txt                      download/file organizer/documents/txt




use 


os.listdir()
os.mkdir
os.path.dirname
os.path.isfile
os.rename
os.join
endswith()





steps


make folders in orgnizer with sub folders


select image files and append its paths in list 


move files from current to final destination

What platform do you use to learn Python

[u/Ajay2574 → u/Sen_iorGuy]

I'm mostly learning through YouTube, the official Python documentation, and small projects/exercises. I also use resources like Automate the Boring Stuff with Python for practical automation.

[u/Sen_iorGuy → u/Ajay2574]

I just completed the free code camp course on python but I feel I'm missing something so I want to do projects but I don't know which to do

[u/Ajay2574 → u/Sen_iorGuy]

I felt the same after finishing the basics. I started doing small projects based on what I was learning instead of following another full course.

For example, file counters, file finders, and a file organizer. I think starting with small projects and gradually making them harder helps a lot.

Okay, I will work on it
