How do you make a Python loop faster?
Programmers are always looking for ways to make their code more efficient. One way to do this is to use a faster loop. Python is a high-level programming language that is widely used by developers and software engineers. It is known for its readability and ease of use. However, one downside of Python is that its loops can be slow. This can be a problem when you need to process large amounts of data. There are several ways to make Python loops faster. One way is to use a faster looping construct, such as C. Another way is to use an optimized library, such as NumPy. Finally, you can vectorize your code, which means converting it into a format that can be run on a GPU or other parallel computing platform. By using these techniques, you can significantly speed up your Python code.
According to Vladislav Zorov, If not talking about NumPy or something, try to use list comprehension expressions where possible. Those are handled by the C code of the Python interpreter, instead of looping in Python. Basically same idea like the NumPy solution, you just don’t want code running in Python.
Example: (Python 3.0)

Python list traversing tip:
Instead of this: for i in range(len(l)): x = l[i]
Use this for i, x in enumerate(l): …
TO keep track of indices and values inside a loop.
Twice faster, and the code looks better.
Finally, developers can also improve the performance of their code by making use of caching. By caching values that are computed inside a loop, programmers can avoid having to recalculate them each time through the loop. By taking these steps, programmers can make their Python code more efficient and faster.
Very Important: Don’t worry about code efficiency until you find yourself needing to worry about code efficiency.
The place where you think about efficiency is within the logic of your implementations.
This is where “big O” discussions come in to play. If you aren’t familiar, here is a link on the topic

- Dear programmers, please save my life!by /u/Middle-Ad2461 (Python) on October 1, 2023 at 1:18 am
Hi to all the programmers worldwide, Please read this and help me through this journey, this may save my life. So straight to the point I’m 25 , know some basic programming (Python,JS) did several experience in Network and other computer fields (but not something very professional) I always wanted to master python and be able to build my own app that can collect data through some internet sources and analysis it for me. I know Python is the right language for that, but I have some major big problems with this! First, there are millions of YT vids out there which I do not find that helpful because I have already done watching like some of them and I find the basic functions just understandable! I need some deeper more straight to point sources to help me get mastered Python. Second, what book do you prefer for Data Analysis and API resources. Based on my learning preference I would like to learn through projects and do reverse engineering I do not want to start from all the beginning based on the fact that I have ADHD and I cannot really focus that much on very simple and boring Syntaxes that are just there available. Can you please help me with reverse engineering submitted by /u/Middle-Ad2461 [link] [comments]

- Gevent based web framework that aims to outperform asgi ?by /u/achaayb (Python) on September 30, 2023 at 10:29 pm
I wanted to kickstart an engaging conversation in this thread dedicated to brainstorming and sharing innovative ideas about a potential new Python framework with a strong emphasis on Gevent. About GAPI: GAPI is a high-performance API framework built on the power of Gevent, designed with scalability as its core principle. It surpasses ASGI-based frameworks by harnessing the efficiency of green threads to deliver exceptional performance. repo : https://github.com/achaayb/GAPI submitted by /u/achaayb [link] [comments]
- Swiss Army Llama: Do tons of useful stuff with local LLMs with a REST API (written in Python)by /u/dicklesworth (Python) on September 30, 2023 at 9:57 pm
GitHub Repo: https://github.com/Dicklesworthstone/swiss_army_llama This project originally started out with a focus on easily generating embeddings from Llama2 and other llama_cpp (gguf) models and storing them in a database, all exposed via a convenient REST api. But since then, I've added a lot more functionality: New endpoint for generating text completions (including specifying custom grammars, like JSON). Get all the embeddings for an entire document-- can be any kind of document (plaintext, PDFs, .doc/.docx, etc.) and it will do OCR on PDFs and images. Submit an audio file (wav/mp3) and it uses whisper to transcribe it into text, then gets the embeddings for the text (after combining the transcription segments into complete sentences). Integrates with my new vector similarity library (`pip install fast_vector_similarity`) to provide an "advanced" semantic search endpoint. This uses a 2-step process: first it uses FAISS to quickly narrow down the set of stored embeddings using cosine similarity, then it uses my vector similarity library to compute a bunch of more sophisticated (and computationally intensive) measures for the final ranking. As a result, I changed the project name to Swiss Army Llama to reflect the new project goal: to be a one stop shop for all your local LLM needs so you can easily integrate this technology in your programming projects. As I think of more useful endpoints to add (I constantly get new feature ideas from my own separate projects-- whenever I want to do something that isn't covered yet, I add a new endpoint or option), I will continue growing the scope of the project. So let me know if there is some functionality that you think would be generally useful, or at least extremely useful for you! A big part of what makes this project useful to me is the FastAPI backbone. Nothing beats a simple REST API with a well-documented Swagger page for ease and familiarity, especially for developers who aren't familiar with LLMs. You can set this up in 1 minute on a fresh box using the docker TLDR commands, come back in 15 minutes, and it's all set up with downloaded models and ready to do inference or get embeddings. It also lets you distribute the various pieces of your application on different machines connected over the internet. submitted by /u/dicklesworth [link] [comments]

- Does async with await optimize Python?by /u/WesternMuch8325 (Python) on September 30, 2023 at 6:53 pm
I am trying to understand if await for an async function that is running one task is any better than just executing the code without async/await. In other words, while my Python code is awaiting for the coroutine to complete, is Python optimized in any way to do other work while waiting that is not directly related to my written code? I'm not familiar with the inner workings of Python, but I'm referring to things like cache clearing or garbage collecting. submitted by /u/WesternMuch8325 [link] [comments]

- RecoverPy 2.1.1: TUI File recovery toolby /u/ThenChoice2 (Python) on September 30, 2023 at 2:58 pm
https://i.redd.it/tlx8f1r5qerb1.gif GitHub : https://github.com/PabloLec/RecoverPy Hey everyone! I'm here to share something I've been working on for nearly three years now, RecoverPy, and its new 2.1.1 version. It's a nifty tool that can really be a lifesaver when you've accidentally deleted or overwritten files. It works its magic by conducting a text-based search to find the lost data. It sports a TUI built with Textual. I found it to be quite enjoyable to use and it seems many others agree, given its rise as one of the most (or the most?) popular TUI libraries in Python, despite still being in beta. Since its creation, RecoverPy has gone through quite a transformation. It's integrated lots of feedback from its user community, improved many aspects to enhance the user experience, and even underwent almost a full rewrite to switch up the TUI library in its second version. Essentially, it uses the strength of grep and dd to sift through partition blocks, giving you a user-friendly way to sift through the results. Interestingly, it found a niche not only among individuals looking to recover files but has also piqued interest in the hacking scene, which was a bit of a pleasant surprise for me. It seems the tool lends itself well to that sphere too. I manage to chip away at it from time to time, given that my free moments are becoming a bit of a rarity these days. It still has room to grow, and if anyone here feels like contributing, I'm more than open to collaborations. Your PRs would certainly be welcome! Feel free to give it a glance, and if you find it interesting or useful, a star on the repository would be greatly appreciated. submitted by /u/ThenChoice2 [link] [comments]
