[Answered] Python Issue

[artavazd]

I cannot run Python scripts on HelioHost at my URL http://benesolutions.heliohost.org/cgi-bin/test.py.

 

It is a simplest script with the following content:

 

#!/usr/bin/python

 

print("Content-type: text/html\n\n")

print("This is a Python script text.")

 

Permissions are 0755, as recommended.

 

The server response was

Internal Server Error

 

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@benesolutions.heliohost.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

 

 

Could you clarify please what I’m doing wrong.

Go to your cpanel's file manager and edit your file. Change your shebang line to look like this:

 

#!/usr/bin/env python

 

Then save the changes with us-ascii as the encoding.

This describes why python throws an error when you edit with Windows:

If you use Notepad++, edit your files in Unix format. Quoted from page above.

Another option is to go to Edit -> EOL Conversion -> Unix Format

Thank you very much - now it works. Never could imagine that Python is so sensitive to EOLs. I've a project with tens of files, all prepared in Windows - it seems, I've to convert all of them. However, thanks again, the advice was really helpful.

I'm sorry, but I've another issue now. As it was pointed on your Website, I can use Python 3.2 (http://www.heliohost.org/home/features/languages/python). Currently it is version 2.43. How could I switch to that Python 3.2? I'm asking because (I'm sure you know that even better then me) there is a lot of differences between those Python versions.

I see Python 2.4, 2.7, and 3.4 on Johnny...

 

If you want 3.4, try using this for the shebang line:

#!/usr/local/bin/python3.4

Thank you very much - your're really very kind and supportive.
