I recently installed Python 3.6.3 on my device. When I type python in my cmd window, it gives me this error. I do have the PATH in the environment variables. Path Lists. This should normally fix it, but python is still not recognized.
I had the same problem, due to a stupid decision from Microsoft.
I had another line in my system path variable:
C:\Users\MyUserName\AppData\Local\Microsoft\WindowsApps
And Windows 10 put a python.exe file there that only redirected me to the Python page of the Microsoft Store:
Since this line was above my true Python path, typing python in the cmd prompt opened the Microsoft Store...
Solution:
Type App execution aliases in the Windows 10 search bar, and then uncheck the aliases for python.exe and python3.exe. More information is here.
The path to the Python executable needs to be in the System PATH variable. Note this is not the User PATH variable.
The OP had Python 3.6.3 installed in C:\Python\Python36-32, however a common default location for installation is in the users AppData\Local\Programs\ folder. This post will assume a Python 3.10 installation in this location. Please adjust as needed for your current Python version and path.
You can confirm the path from the command prompt by checking the Python executable directly from the folder.
cd %LOCALAPPDATA%\Programs\Python\Python310
python --version
This should print the Python interpreter version. For example, Python 3.10.4.
Add the following entries to the System PATH:
%LOCALAPPDATA%\Programs\Python\Python310 for the python executable
%LOCALAPPDATA%\Programs\Python\Python310\Scripts for tools such as pip
After adding the path to the System PATH variable, make sure you close and reopen any command prompts, so they use the updated PATH.
If it is still not working, as mentioned in the previous answers, then simply move up the path, as shown in the screenshot.
You get this error, because the python.exe path has not been added to the System environment variable. To do that, simply:
go to the path C:\Users\%Username%\AppData\Local\Programs\Python\Python37-32 which contains python.exe
copy the path and open System environment variables and in the variable section look for variable called Path. If not, create a new variable with Variable Name as Path and value as the copied path
Once you do that, close the window and simply open cmd. Type python and you should get something like this:
If you are trying to install the new Python version, python-3.9.6, then click the checkbox of Add Python 3.9 to PATH
This happens because the path doesn't exist in environment variables.
To fix this:
Rerun the installer
Choose Modify
In optional feature click "Next"
In advanced option tick the "Add Python to environment variables"
Install
All the answers on Stack Overflow_ about it were obsolete, so I decided to add this. The path variable that needs to be added is,
C:\Users\Username\AppData\Local\Programs\Python\Python36-32
Note that everyone may have a different Username.
If you are working with the command prompt and if you are facing the issue even after adding the Python path to system variable PATH:
Remember to restart the command prompt (cmde.exe).
I too was struggling with this issue, and everything was configured correctly. I installed and setup my system path variables as one would. And everything was fine. Then upon reboot windows would not recognize 'python' as a command as if it were unaware of the path variable. Double checked to confirm everything was still setup correctly (it was).
It only started to work again after I manually browsed to the directory in which python.exe existed, and ran 'python'. After that windows seemed to recognize my path variable and I could call 'python' from where ever need be. Very odd. Figured I'd share in case someone else runs into this.
For Python 3.6, there are actually two path entries. Also, it's best to use the %USERPROFILE% rather than hard coding it.
%USERPROFILE%\AppData\Local\Programs\Python\Python36
%USERPROFILE%\AppData\Local\Programs\Python\Python36\Scripts

Good day!
Installed the Python 3.9.1, checked "Add to path", the cmd did not work though.
Added Environment Variable Path, both folder
C:\Users\XXXXX\AppData\Local\Programs\Python\Python39
(file manager opens the path to python.exe just fine)
and script lines:
C:\Users\XXXXX\AppData\Local\Programs\Python\Python39
Still the commands python -version and pip --version do not work from the command line.
Py --version works just fine though.
Anyone might share and idea what might be the reason?
This happens more often than one would think.
When you installed python from python.org and follow the installer, post install, you should check your environment variables, and verify that you have no other python installation (or if you do just name them appropriately).
Often you can find that there is an Environment Variable, that includes a python version on the global Environment Variable Path.
To verify that you are targeting the correct python version put these two directories (replace, user and python version), at the top of your PATH (user's path), and check that there are no conflicts with the rest of the PATH variables.
C:\Users\XXXXX\AppData\Local\Programs\Python\PythonXX
C:\Users\XXXXX\AppData\Local\Programs\Python\PythonXX\Scripts
If you had Python installed in the system before, the new path is added at the end of PATH system variable and when system looks for python.exe it finds first the old version that is available under a different folder.
If you used a command window opened before the new version got installed, it is also possible that system variables did not reload. Close it and use a new one to check.
The Command Prompt does not do anything when I use the Python command to execute a module. It does not even do anything when I use it at all; it just pretends that I did not do anything, and goes back to the current working directory. Attached is a screen shot for clarity.
Apparently, if you call python from Windows' Command Prompt (at least with my home computer), it will look for any python version installed using Windows Store, so if you just type python, it will open the Windows Store for you to install.
If you have Python installed, try to call full path to executable or try to add the path containing your Python executable (in my case, C:\Python38) to the system environment variable PATH:
Search for "Edit the system environment variables".
Click the Environment variables... button (in the Advanced tab)
Edit PATH and append ;C:\Python27 to the end (substitute your Python version)
Click OK and reopen cmd for change to take effect.
Update.
I simply uninstalled and reinstalled Python. Once I did that, the program works as it should in CMD.
If you have python already installed, you should just be able to type 'python' alone then press enter. It should then give you a space to execute python code. It could be simple fix, but if not it's still worth a shot.
When its the first time you're going to install python on Windows it shows you the option Add to path unchecked, so you just need to check that option and install python, you can uninstall python and installet again with the check, this fix the problem.
I just use the IDLE, it is the easiest way to run python scripts. Just open up IDLE and click on File < Open.. < and select your file. Then make any last minute changes and click on File < Save. Click on Run < Run Module (or F5) to run the python script. Done.
This is great for people that want to use python 2.7 or just don't want to install the python application from the Microsoft store.
Sometimes the order in which the PATH environment variable is set also matters; if the Windows store variable is before the path where Python is installed then the windows store will open when you type python.
I tried following the instructions here with no luck.
Attached is my cmd prompt output. Any suggestions?
It looks like pip is not on your path. Try issuing the pip command again in the folder C:\Python27\Scripts.
I do not suggest using setx and it's unfortunate that search results specifically for pip point to that advice e.g. this. The truncation message to 1024 characters is real. It's very easy for that to simply knock things out of your PATH unintentionally and you might not know what got kicked out in Python's place, if it gets added at all. It will execute and then tell you the issue after the PATH has been modified. You do need to add pip to your PATH, though.
Instead, edit through right clicking My Computer and selecting "properties" (this is Windows 7):
As illustrated:
Advanced System Settings
Environment Variables
Edit the PATH for "User variables". Each path should be separated by ;.
You need to add the path to pip.exe. It's likely in the Scripts subfolder of the Python installation. You need to only provide the directory path, not reference the .exe directly.
setx does have its uses. In really locked-down systems, you can still use it without admin privileges; make of that what you will.
well, I am guessing you are using Windows system. Then I'm also guessing you specified wrong path to the pip program. Check again where is your pip.exe located and add this location to the PATH instead.
The faster way is to reinstall python, and click on the box in the installer that says:
Add Python X.X to PATH
I have just installed Python on my Windows 7. I thought that after that I will be able to run python on the command prompt but it is not the case. After the installation I also found out that I can run the python command shell. This is nice. But what should I do if I want to save my program in a file and then I want to run this program (in Linux, for example, I typed "python file_name.py" in the command line).
You need to add the python bin directory to your path. Follow the instructions here and add c:\python26\bin to the path (unless you installed python in a non-default location).
Is python.exe in your windows path? Try to look at the PATH environment variable and see if the installation folder of python is listed there.
You need to update your environment variables to include the path to the Python executable.
On XP you can do this by right clicking on "My Computer" -> Properties and then going to the "Advanced" tab.
I have installed python and django in my system that uses win vista. Now when I go to command prompt and type python or django-admin.py both are not working. Every time I need to set the path to the python folder manually. But i have seen these commands running even without setting path. So how do i make it to run properly?
You probably need to add Python to you dos path. Here's a video that may help you out:
http://showmedo.com/videotutorials/video?name=960000&fromSeriesID=96
you can't run a command that isn't in your path. it should be set globally when you installed python.
type 'set' at a dos prompt and look at the PATH variable. c:\python25 (or whever you installed python) has to be in that variable ie PATH=c:\windows;c:\python25;... etc
if it isn't in PATH then you or the installer missed the part where you needed to set it. It can be done from the 'Environment Variables' button in the 'System' control panel.
Either use the system control panel to set the PATH environment variable that applies permanently or
Reinstall Python as a system administrator so that the installer can set the registry and environment variables for you.
If you install the "just for me" option, then you have to set the PATH variable in the control panel.
In your path, I think you need to have both the location of the Python install and the Python\Scripts folder. For example, on XP, I have C:\Python25;C:\Python25\Scripts. Can you verify that you have both?
