How can I execute Python scripts using Anaconda s version of Python

Question

I recently downloaded the Anaconda distribution for Python  I noticed that if I write and execute a Python script  by double-clicking on its icon   my computer  running on Windows 8  will execute it using my old version of Python rather than Anaconda s version  So for example  if my script contains import matplotlib  I will receive an error  Is there a way to get my scripts to use Anaconda s version of Python instead   I know that I can just open Anaconda s version of Python in the command prompt and manually import it  but I d like to set things us so that I can just double-click on a  py file and Anaconda s version of Python is automatically used

The instructions in the official Python documentation worked for me: https://docs.python.org/2/using/windows.html#executing-scripts

Launch a command prompt.
Associate the correct file group with .py scripts:
```
assoc .py=Python.File
```

Redirect all Python files to the new executable:

    ftype Python.File=C:\Path\to\pythonw.exe "%1" %*

The example shows how to associate the .py extension with the .pyw executable, but it works if you want to associate the .py extension with the Anaconda Python executable. You need administrative rights. The name "Python.File" could be anything, you just have to make sure is the same name in the ftype command. When you finish and before you try double-clicking the .py file, you must change the "Open with" in the file properties. The file type will be now ".py" and it is opened with the Anaconda python.exe.

Set your python path to the Anaconda version instead  Windows has a built-in dialog for changing environment variables  following guide applies to XP classical view   Right-click the icon for your machine  usually located on your Desktop and called    My Computer     and choose Properties there  Then  open the Advanced tab and click the Environment Variables button   In short  your path is   My Computer   Properties   Advanced   Environment Variables In this dialog  you can add or modify User and System variables  To change System variables  you need non-restricted access to your machine  i e  Administrator rights    Find your PATH variable and add the location of your Anaconda directory   Example of someone doing it here  How to add to the PYTHONPATH in Windows  so it finds my modules packages  Make sure that you sub path out for the Anaconda file though

I like to run a  bare-bones  version of Python 2 to verify scripts that I create for other people without an advanced python setup  But Anaconda and Python 3 have a lot of nice features  To enjoy both things on the same computer I do this on my Windows computer which allows me to easily switch   C  Users gt python --version Python 2 7 11  C  Users gt conda create --name p3 python 3  C  Users gt conda info --envs Using Anaconda Cloud api site https   api anaconda org   conda environments    p3                       C  Anaconda3 envs p3 root                     C  Anaconda3  C  Users gt activate p3 Deactivating environment  C  Anaconda3     Activating environment  C  Anaconda3 envs p3       p3  C  Users gt python --version Python 3 5 1    Continuum Analytics  Inc    For more info  http   conda pydata org docs test-drive html

I know this is old  but none of the answers here is a real solution if you want to be able to double-click Python files and have the correct interpreter used without modifying your PYTHONPATH or PATH every time you want to use a different interpreter  Sure  from the command line  activate my-environment works  but OP specifically asked about double-clicking    In this case  the correct thing to do is use the Python launcher for Windows   Then  all you have to do is add    path to interpreter python exe to the top of your script  Unfortunately  although the launcher comes standard with Python 3 3   it is not included with Anaconda  see Python  amp  Windows  Where is the python launcher    and the simplest thing to do is to install it separately from here

You can try to change the default  py program via policy management  Go to windows  search for regedit  right click it  And then run as administrator  Then  you can search the key word  python exe  And change your Python27 path to you Anaconda path

don t know windows 8 but you can probably set the default prog for a specific extension  for example on windows 7 you do right click    open with  then you select the prog you want and select  use this prog as default   or you can remove your old version of python from your path and add the one of the anaconda
