It also explains the Python execution lifecycle (interpreter, CPython bytecode, .pyc caching) and maps these concepts to .NET equivalents like IL, the CLR, JIT, and the BCL, ending with a side-by-side comparison table of .NET and Python concepts. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I create and activate a Python virtual environment on Windows? Run python -m venv .venv in your project folder to create the virtual environment, which creates Include, Lib, and Scripts subfolders. Activate it in PowerShell with .\.venv\Scripts\activate; activation updates PATH so python and pip commands resolve to the versions inside .venv rather than the global install. _daily.dev surfaces practical setup walkthroughs like this for developers getting a new language environment running._ ### What is the difference between Python bytecode and .NET IL? Python bytecode is CPython's internal, lower-level representation of source code used only by its own interpreter loop, cached as .pyc files under __pycache__ to speed up imports, and not meant as a stable cross-implementation format. .NET IL, by contrast, is a well-defined intermediate language with rich type metadata designed to be JIT-compiled to native code by the CLR across implementations. _Developers moving between runtimes can compare execution models like this on daily.dev before switching ecosystems._ ### Do I need to activate a Python virtual environment before running pip install? Yes, otherwise pip installs the package into the global Python installation's site-packages folder instead of the isolated virtual environment, which can cause dependency conflicts. When the venv is active, pip installs into the Lib\site-packages folder inside .venv instead, keeping dependencies project-local similar to a project-scoped NuGet restore. _Anyone debugging a stray global package install can find similar troubleshooting context on daily.dev._ ## Similar posts on daily.dev - [Virtual Environment in Python \(Venv\)](https://daily.dev/posts/virtual-environment-in-python-venv--7efouzsbc) · Medium · 0 upvotes · 0 comments - [How to use virtual environments in Python](https://daily.dev/posts/how-to-use-virtual-environments-in-python-cnm4rzle8) · InfoWorld · 0 upvotes · 0 comments - [Your Python Coding Environment on Windows: Setup Guide Quiz – Real Python](https://daily.dev/posts/your-python-coding-environment-on-windows-setup-guide-quiz-real-python-yn0wmredm) · Real Python · 1 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#.net](https://daily.dev/tags/.net), [#pip](https://daily.dev/tags/pip), [#cpython](https://daily.dev/tags/cpython) [View this post on daily.dev](https://daily.dev/posts/python-for-net-devs-introduction-virtual-environments-package-management-and-execution-lifecycl-r1nzo2v28) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Python for .NET devs: Introduction, virtual environments, package management, and execution lifecycle","url":"https://daily.dev/posts/python-for-net-devs-introduction-virtual-environments-package-management-and-execution-lifecycl-r1nzo2v28","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/python-for-net-devs-introduction-virtual-environments-package-management-and-execution-lifecycl-r1nzo2v28"},"datePublished":"2026-10-04T13:07:08.250Z","dateModified":"2026-10-04T13:18:18.275Z","description":"A .NET developer's introductory walkthrough of Python aimed at readers coming from the .NET ecosystem, covering installing Python on Windows, creating and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/307f0a8f0ddf5d7c5a99675d6e1d38d7?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/307f0a8f0ddf5d7c5a99675d6e1d38d7?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Code4IT","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Code4IT","logo":"https://media.daily.dev/image/upload/s--OaaG4G10--/f_auto,q_auto/v1791119049/logos/code4it?_a=BAMAMicg0","url":"https://daily.dev/sources/code4it"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/python-for-net-devs-introduction-virtual-environments-package-management-and-execution-lifecycl-r1nzo2v28","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"python,.net,pip,cpython","timeRequired":"PT14M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Code4IT","item":"https://daily.dev/sources/code4it"},{"@type":"ListItem","position":3,"name":"Python for .NET devs: Introduction, virtual environments, package management, and execution lifecycle"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/python-for-net-devs-introduction-virtual-environments-package-management-and-execution-lifecycl-r1nzo2v28#faq","mainEntity":[{"@type":"Question","name":"How do I create and activate a Python virtual environment on Windows?","acceptedAnswer":{"@type":"Answer","text":"Run python -m venv .venv in your project folder to create the virtual environment, which creates Include, Lib, and Scripts subfolders.
