When you want to use the Python interpreter again, just click the Windows Start button and select the Anaconda Prompt and type python. To close the Anaconda Prompt, you can either close the window with the mouse, or type exit, no parenthesis necessary. The () is needed to stop the Python interpreter and get back out to the Anaconda Prompt. Note the double parenthesis at the end of the exit() command. To close the Python interpreter, type exit() at the prompt >. You should see the Zen of Python by Tim Peters With the interpreter running, you will see a set of greater-than symbols > before the cursor. You should see something like Python 3.6.1. The python command starts the Python interpreter, also called the Python REPL (for Read Evaluate Print Loop). The black screen and text that makes up the Anaconda Prompt doesn't look like much, but it is really helpful for problem solvers using Python.Īt the Anaconda prompt, type python and hit. Anaconda is the Python distribution and the Anaconda Prompt is a command line shell (a program where you type in commands instead of using a mouse). exe installerĪt the beginning of the install, you need to click Next to confirm the installation.Īt the Advanced Installation Options screen, I recommend that you do not check "Add Anaconda to my PATH environment variable"Īfter the installation of Anaconda is complete, you can go to the Windows start menu and select the Anaconda Prompt. Updated packages include: pandas 1.4.4 Matplotlib 3.5. Once the download completes, open and run the. The Anaconda Distribution 2022.10 installer and base environment use Python 3.9 with conda v22.9.0. The download is quite large (over 500 MB) so it may take a while to for Anaconda to download. You can still download Anaconda if you click and don't enter your Work Email address. If you are unsure if your computer is running a 64-bit or 32-bit version of Windows, select 64-bit as 64-bit Windows is most common. For problem solvers, select the Python 3.6 version. At the time of writing, the most recent release was the Python 3.6 Version. Select Windows where the three operating systems are listed.ĭownload the most recent Python 3 release. The Anaconda Downloads Page will look something like this: Open the Anaconda Prompt and run some Python code These three packages are very useful for problem solvers and will be discussed in subsequent chapters.įollow the steps below to install the Anaconda distribution of Python on Windows. Anaconda comes bundled with about 600 packages pre-installed including NumPy, Matplotlib and SymPy. Anaconda is free (although the download is large which can take time) and can be installed on school or work computers where you don't have administrator access or the ability to install new programs. I think the Anaconda distribution of Python is the best option for problem solvers who want to use Python. This section details the installation of the Anaconda distribution of Python on Windows 10. Installing Anaconda on Windows Installing Anaconda on Windowsįor problem solvers, I recommend installing and using the Anaconda distribution of Python. Problem Solving with Python Book Construction Open the Anaconda Prompt from the Windows start menu You cannot, or, better, you shouldn't, use the system's installation in your virtual environment, as this would defy the purpose of having a virtual environment in the first place and could easily lead to a broken system.5. So, in your case in which you wanted to use Python 3.8 in my_env, Python 3.8 would have to be downloaded again, since, as said before, the environment's Python version is independent of the main OS's version. In the case of Python specifically, this is one of the most common reasons that users end up with a broken system. It has the big advantage that all packages installed in it won't affect the ones that come preinstalled with the OS, so they can be handled (updated, downgraded, removed, etc.) separately, effectively eliminating breakages of the main system due to unsatisfied dependencies, etc. Using the commands conda activate my_env and conda install python=3.8 you first tell conda to activate the virtual environment named my_env and then install Python 3.8 in it.Ī virtual environment is an environment (think of it as a special folder) that is used to install Python (or another supported language), as well as packages and their dependencies, independently from the main OS. What you observed is correct and is exactly how conda is supposed to work.
