The error is pretty clear. The file <code>hello.py</code> is not an executable file. You need to specify the executable:

<pre><code>subprocess.call(['python.exe', 'hello.py', 'htmlfilename.htm'])
</code></pre>

You'll need <code>python.exe</code> to be visible on the search path, or you could pass the full path to the executable file that is running the calling script:

<pre><code>import sys
subprocess.call([sys.executable, 'hello.py', 'htmlfilename.htm'])

Python installers usually register .py files with the system. If you run the shell explicitly, it works:

<pre><code>import subprocess
subprocess.call(['hello.py', 'htmlfilename.htm'], shell=True)
# --- or ----
subprocess.call('hello.py htmlfilename.htm', shell=True)

You can check your file associations on the command line with

<pre><code>C:\&gt;assoc .py
.py=Python.File

C:\&gt;ftype Python.File
Python.File="C:\Python27\python.exe" "%1" %*

OSError: [WinError 193] %1 is not a valid Win32 application

This error is most probably due to this line import subprocess 

I had the same issue and had solved it by uninstalling and reinstalling python and anaconda then i used jupyter and wrote pip install numpy this gave me the whole path where it was getting my site-packages from i deleted my site-packages folder and then the error dissappeared. Actually because i had 2 folders for site-packages one with anaconda and other somewhere in app data(which had some issues in it), since i deleted that site-package folder then it automatically started taking my libraries from site-package folder which was with anaconda hence the problem was solved.
