Python is one of the most widely used programming languages. It’s getting a lot of popularity these days because of so many Python frameworks in IoT, Machine Learning, Deep Learning, and Artificial Intelligent space.
These Python Tutorials will help you in getting mastery over the Python Programming. The tips and tricks shared by us will enable you to write pythonic code with high performance, reusability, readability, and maintainability.
Python raises a TypeError when a function call passes a keyword argument the function’s signature does not accept. The traceback names the offending argument so you can fix the call site, the function definition, or both. An unexpected keyword argument…
A keylogger records every keystroke a user types. The Python implementation below uses pynput to capture keys and the standard logging module to persist them. A minimal Python keylogger uses pynput.keyboard.Listener to hook the OS keyboard event stream and the…
Random colors are a small exercise with a surprisingly wide footprint. They show up in test fixtures, data visualization placeholders, avatar generators, and the first 20 minutes of any Python graphics tutorial. Below are five ways to generate a random…
Last week a junior dev on my team had a list of route stops and a tuple of fallback hubs, and asked which Python incantation would fold the tuple into the list. The answer is not a single incantation. There…
Last quarter I had to plan a 12-stop delivery loop and the route my gut picked came out 38% longer than the version a small Python script returned in under a second. That gap is the travelling salesman problem (TSP):…
I had a fresh install of macOS Sequoia and typed python3 in a fresh shell. The system found one, ran my script, and returned a version. So far so good. Then I asked the script for sys.executable, and the answer…
I had a tuple of integers from a config file and a NumPy function that expected an array. The conversion was a one-liner, but I wanted to be deliberate about which one I called. Tuple, list, array module, NumPy. Each…
I tried to write a++ in Python once and got a SyntaxError pointing at the second plus. The fix was simple, but the explanation was not, and the answer to why Python chose not to ship an increment operator is…
You are about to see a worked RSA example with p=61, q=53, the primes from the original 1977 RSA paper. The previous version of this article used p=3, q=7 and got d=5.0, which only decrypts by coincidence. The fixed version…
You need the middle of a Python list. There is no list.middle() method, but the answer is three lines once you know the recipe: check the length, branch on odd or even, return the slice. The recipe catches beginners because…
