How can I find where Python is installed on Windows?
PythonWindowsPathPython Problem Overview
I want to find out my Python installation path on Windows. For example:
C:\Python25
How can I find where Python is installed?
Python Solutions
Solution 1 - Python
In your Python interpreter, type the following commands:
>>> import os
>>> import sys
>>> os.path.dirname(sys.executable)
'C:\\Python25'
Also, you can club all these and use a single line command. Open cmd and enter following command
python -c "import os, sys; print(os.path.dirname(sys.executable))"
Solution 2 - Python
If you have Python in your environment variable then you can use the following command in cmd or powershell:
where python
or for Unix enviroment
which python
command line image :
Solution 3 - Python
It would be either of
- C:\Python36
- C:\Users\(Your logged in User)\AppData\Local\Programs\Python\Python36
Solution 4 - Python
If you need to know the installed path under Windows without starting the python interpreter, have a look in the Windows registry.
Each installed Python version will have a registry key in either:
HKLM\SOFTWARE\Python\PythonCore\versionnumber\InstallPathHKCU\SOFTWARE\Python\PythonCore\versionnumber\InstallPath
In 64-bit Windows, it will be under the Wow6432Node key:
HKLM\SOFTWARE\Wow6432Node\Python\PythonCore\versionnumber\InstallPath
Solution 5 - Python
Simple way is
- open CMD
- type
where pythonin cmd
Solution 6 - Python
On my windows installation, I get these results:
>>> import sys
>>> sys.executable
'C:\\Python26\\python.exe'
>>> sys.platform
'win32'
>>>
(You can also look in sys.path for reasonable locations.)
Solution 7 - Python
If you have the py command installed, which you likely do, then just use the --list-paths/-0p argument to the command:
py --list-paths
Example output:
> Installed Pythons found by py Launcher for Windows
-3.8-32 C:\Users\cscott\AppData\Local\Programs\Python\Python38-32\python.exe *
-2.7-64 C:\Python27\python.exe
The * indicates the currently active version for scripts executed using the py command.
Solution 8 - Python
Its generally
'C:\Users\user-name\AppData\Local\Programs\Python\Python-version'
or try using (in cmd )
>> where python
Solution 9 - Python
In the sys package, you can find a lot of useful information about your installation:
import sys
print sys.executable
print sys.exec_prefix
I'm not sure what this will give on your Windows system, but on my Mac executable points to the Python binary and exec_prefix to the installation root.
You could also try this for inspecting your sys module:
import sys
for k,v in sys.__dict__.items():
if not callable(v):
print "%20s: %s" % (k,repr(v))
Solution 10 - Python
If You want the Path After successful installation then first open you CMD and type python or python -i
It Will Open interactive shell for You and Then type
>import sys > >sys.executable
Hit enter and you will get path where your python is installed ...
Solution 11 - Python
To know where Python is installed you can execute where python in your cmd.exe.
Solution 12 - Python
You can search for the "environmental variable for you account". If you have added the Python in the path, it'll show as "path" in your environmental variable account.
but almost always you will find it in "C:\Users%User_name%\AppData\Local\Programs\Python\Python_version"
the 'AppData' folder may be hidden, make it visible from the view section of toolbar.
Solution 13 - Python
If anyone needs to do this in C# I'm using the following code:
static string GetPythonExecutablePath(int major = 3)
{
var software = "SOFTWARE";
var key = Registry.CurrentUser.OpenSubKey(software);
if (key == null)
key = Registry.LocalMachine.OpenSubKey(software);
if (key == null)
return null;
var pythonCoreKey = key.OpenSubKey(@"Python\PythonCore");
if (pythonCoreKey == null)
pythonCoreKey = key.OpenSubKey(@"Wow6432Node\Python\PythonCore");
if (pythonCoreKey == null)
return null;
var pythonVersionRegex = new Regex("^" + major + @"\.(\d+)-(\d+)$");
var targetVersion = pythonCoreKey.GetSubKeyNames().
Select(n => pythonVersionRegex.Match(n)).
Where(m => m.Success).
OrderByDescending(m => int.Parse(m.Groups[1].Value)).
ThenByDescending(m => int.Parse(m.Groups[2].Value)).
Select(m => m.Groups[0].Value).First();
var installPathKey = pythonCoreKey.OpenSubKey(targetVersion + @"\InstallPath");
if (installPathKey == null)
return null;
return (string)installPathKey.GetValue("ExecutablePath");
}
Solution 14 - Python
This worked for me: C:\Users\Your_user_name\AppData\Local\Programs\Python
My currently installed python version is 3.7.0
Hope this helps!
Solution 15 - Python
Go to C:\Users\USER\AppData\Local\Programs\Python\Python36 if it is not there then open console by windows+^R Then type cmd and hit enter type python if installed in your local file it will show you its version from there type the following import os import sys os.path.dirname(sys.executable)
Solution 16 - Python
You could have many versions of Python installed on your machine. So if you're in Windows at a command prompt, entering something like this...
py --version
...should tell you what version you're using at the moment. (Maybe replace py with python or python3 if py doesn't work). Anyway you'd see something like
Python 3.10.2
If you then create a virtual environment using something like this...
py -m venv venv
...that environment will also use that Python version. To verify, activate the environment...
venv\scripts\activate.bat
You'll see the name of the command prompt. Now if execute:
where python
...it will show you which Python executable that virtual environment uses. It will be a copy of Python.exe what's actually in the Scripts subfolder of the virtual environment folder. Of course to see which version that is, again use py --version.
Solution 17 - Python
You can find it in the Windows GUI, but you need to select “show hidden” in the menu. Directory where python is installed on my Win10 computer:
C:\Users\username\AppData\Local\Programs\Python\Python310
Very handy if you use python pip to install packages.
Solution 18 - Python
Make use of the Python Launcher for Windows (available as of 3.3). It is compatible with all available versions of python.
First, check if the launcher is available:
py
starts the latest installed version of Python
To see all Python versions available on your system and their path:
py -0p
or
py --list-paths
For a specific Python version path—especially useful with multiple python installations:
py -3.7 -c "import os, sys; print(os.path.dirname(sys.executable))"
python 2
py -2 -c "import os, sys; print(os.path.dirname(sys.executable))"
py installed location is C:\Windows\py.exe if installed for all users, otherwise can be found at C:\Users\username\AppData\Local\Programs\Python\Launcher.
It does not require the environment PATH variable to be set if installed for all users.
Solution 19 - Python
if you still stuck or you get this
C:\\\Users\\\name of your\\\AppData\\\Local\\\Programs\\\Python\\\Python36
simply do this replace 2 \ with one
C:\Users\akshay\AppData\Local\Programs\Python\Python36
Solution 20 - Python
I installed 2 and 3 and had the same problem finding 3. Fortunately, typing path at the windows path let me find where I had installed it. The path was an option when I installed Python which I just forgot. If you didn't select setting the path when you installed Python 3 that probably won't work - unless you manually updated the path when you installed it. In my case it was at c:\Program Files\Python37\python.exe
Solution 21 - Python
If you use anaconda navigator on windows, you can go too enviornments and scroll over the enviornments, the root enviorment will indicate where it is installed. It can help if you want to use this enviorment when you need to connect this to other applications, where you want to integrate some python code.

Simplest Answer
There are many Pythonic Ways to Answer, this Question, but I am going to stick to the old and trusted way.
Steps on Windows
- Open Search and Type Edit the System Environment Variables.
- Then Click on the "Environment Variables" Button in the Down Corner.
- There you can see all of the paths associated to where python, pip and other binaries are located that you call on command line.
