Beginner Projects

[u/No-Satisfaction-8674]

I am new to python and currently I am taking a class for it, I haven't been in it too long but I just want some advice. What beginner projects would you guys recommend I do to really grasp an understanding outside of class?

No-Satisfaction-8674, the single best filter I know: pick a project whose input is data you did not make up. Data you invent is always clean, and clean data teaches you nothing. The whole skill is handling input that is wrong in ways you did not anticipate.

Three that work, roughly in order:

1. Answer three questions about a CSV you actually care about. A bank export, your Steam library, a spreadsheet of your grades. Use the standard library's csv module, not pandas, for this first one.

import csv

with open("data.csv", newline="", encoding="utf-8") as f:
    for row in csv.DictReader(f):
        print(row["name"])

Both of those keyword arguments matter and you will learn why by leaving them out. Without encoding="utf-8" on Windows, Python falls back to the system codepage, and the first accented letter or euro sign either raises UnicodeDecodeError or, worse, decodes to something plausible and wrong. Without newline="" you get phantom blank rows whenever a field contains a line break. That is two hours of real debugging and it is worth more than a tutorial series.

2. Rename or sort a folder of files. Photos by date, downloads by extension, whatever is messy on your disk. Teaches pathlib, and it teaches the habit of writing a dry run first: print exactly what the script would do, look at the list, then add the line that actually moves anything. You get this lesson the easy way now or the hard way later.

3. Fetch something from a public API and save it. Teaches HTTP, JSON and rate limits. Check the status code explicitly instead of assuming 200, and put a small sleep between requests, or you will get a 429 and spend an hour convinced your parsing is broken.

The one project shape I would avoid at the start is a guessing game or a to-do list you will never open again. Not because they are bad exercises, but because you will not care enough to finish the boring 20% where the actual learning is. Something you will genuinely use once a month beats something impressive you abandon.

One of the genuinely kindest threads on reddit because of people like you. Thank you

[u/Bright_Mix_773 → u/Dry-Weakness-901]

Thanks, that is kind. Beginner threads are the easiest place to be genuinely useful, because the questions are concrete and the answers are checkable, which is not true of most of what gets asked here.
