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 prints very small floats in scientific notation, like 1e-05 instead of 0.00001. The decimal form comes back with the right format specifier, in your output and in the files you write. Where the exponent form comes from Python stores…
A requirements.txt file lists the packages a project needs so a fresh install gets the same environment. Generating it from your project instead of the whole machine keeps the list to just the packages you use. What pip actually does…
Python stops on the line the moment it meets && inside an if statement, and the caret lands under the second ampersand. Every C-family language accepts those two characters for logical conjunction, so a parser error reads like a bug…
Define a custom contains method on your own class and the in operator will call it instead of scanning anything. Print one line inside that method and you can watch Python delegate every membership check, which is the whole mechanism…
Print the result of the Python map function and you get an address instead of a list, because nothing has run yet. The four numbers you passed in are still waiting inside an iterator, and the values only appear when…
A Python list comprehension builds a new list from an iterable in one expression. Put the output expression first, then the for clause, and add an if clause when items need filtering. Start with the smallest list comprehension Use a…
A Python dictionary stores values under keys, so you can retrieve, update, and remove data by name. Create a dictionary Use braces for a literal dictionary. Each key is followed by a value, and pairs are separated by commas. A…
A Python vector database is useful when you need semantic retrieval, but not every retrieval job needs a server, collections, filters, and operational ownership. turbovec is a local Rust-backed vector index with Python bindings that lets you add embeddings, search…
Most beginning programmers default to the three largest tech channels on YouTube they can find. Although those channels do have their place, actual communities of programmers on Reddit and Discord frequently point students to less well-known creators. These lesser-known channels…
NameError is common in Python, and it is usually easy to fix once you slow down and read what the traceback is telling you. I hit it often while coding, especially on larger codebases where functions, imports, and helper names…
