How do you change file association for .py Python

Question

When I type assoc .py I get .py=py_auto_file. When I type ftype py_auto_file I get py_auto_file="C:\Program Files\Adobe\Photoshop 7.0\Photoshop.exe" "%1"

How do I make py_auto_file="C:\Python27"?

Answer 1

Right-click on .py file and set default program as python.exe

Answer 2

It appears Photoshop may recognize a .py file format and has associated "py_auto_file" with the .py extension.

You can use the following command to locate the python file types:

C:\>ftype | findstr -i python
Python.CompiledFile="C:\Python27\python.exe" "%1" %*
Python.File="C:\Python27\python.exe" "%1" %*
Python.NoConFile="C:\Python27\pythonw.exe" "%1" %*

The next command shows the correct associations from my system:

C:\>assoc | findstr -i python
.py=Python.File
.pyc=Python.CompiledFile
.pyo=Python.CompiledFile
.pyw=Python.NoConFile

You can fix the associations with the following commands:

assoc .py=Python.File
assoc .pyc=Python.CompiledFile
assoc .pyo=Python.CompiledFile
assoc .pyw=Python.NoConFile

Answer 3

You should pass script name %1 and all command-line parameters %* to Python27 executable. To do this, simply execute

ftype py_auto_file="C:\Python27\bin\python.exe" "%1" %*
