![]() Click on the “Edit the system environment variables” link. On Windows, open the Control Panel and search for “environment variables”. The most common way is to check the environment variables. There are a few ways to check if Python is installed on your computer. If you want to use a specific version of Python, you can set it as your default using the conda command-line tool:Ĭonda install python=3 # installs specific version of PythonĬonda remove python=3 # removes specific version of Python This should return a list of all the versions of Python that are available through Anaconda distribution, along with their corresponding paths. # should return something like conda 4.3.21 If you’re using Anaconda distribution for scientific computing with Python, then you can use the conda command-line tool to check your version of Python: The value of this variable will tell you which version of Python is currently active in your environment. Under System Variables, look for a variable called PYTHON_VERSION. On Windows, go to Control Panel > System > Advanced > Environment Variables. If you see something like Python 3.6.1, then you have version 3 installed.Īnother way to find out which version of Python you have is to check your environment variables. If you see something like Python 2.7.12, then you have version 2.7 installed. If you’re using a Unix-based operating system, such as Linux or macOS, you can check your version of Python by opening a terminal window and typing: How do you check which version of Python you have? There are a few ways to do this: Although compatible with earlier versions, Python 3 introduces many differences from Python 2 that can cause existing code to break if not ported (or fixed). Since then, significant new features have been added in subsequent releases. Version 3 was released on December 3, 2008. Python version numbers are released according to a schedule. The PSF’s stated mission is “to foster development of the Python community and to defend the rights of Python users”. They support and promote the development of Python through financial contributions, hosting conferences, and managing the PSF License Agreement. The Python Software Foundation (PSF) is the organization behind Python. Since its inception, Python has been open source software and has had an enthusiastic and growing developer base, both volunteer and paid. The Python 2.0 release was coordinated by Barry Warsaw and Anthony Baxter. Guido van Rossum is still the principal author of Python. The Python programming language was created in the late 1980s by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands as a successor to the ABC programming language (itself inspired by SETL). Python is easy to learn for beginners and has a wide range of applications in scripting, automation, data science, machine learning, and web development. Python is a programming language with many characteristics, including an intuitive syntax and powerful data structures, which can lead to efficient code.
