Python: Importing modules into CGI script

问题

I'm hoping someone might be able to explain to me why this is happening?

I am running httpd on Centos 7 with Python 2.7

I have a python module in /home/user/Path/to/module.py. Lets say, for example, it prints "Hello World!"

print("Hello World!")

I then try to import it into the file /var/www/cgi-bin/index.py like so:

#!/usr/bin/python
import sys
sys.path.append('/home/user/Path/to/')

print('Content-type: text/html\n\n')
print('<!DOCTYPE html>')
print('<html lang="en">')
print('<head>')
print('</head>')
print('<body>')
print('<h1>')
import module
print('</h1>')
print('</body>')
print('</html>')

If I were to run this from the terminal I get the following:

Content-type: text/html


<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<h1>
Hello World!
</h1>
</body>
</html>

However, when I curl this URL curl http://127.0.0.1/cgi-bin/index.py I get the following message:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>
</head><body>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete
your request.</p>
<p>Please contact the server administrator at
root@localhost to inform them of the time this error occurred,
and the actions you performed just before this error.</p>
<p>More information about this error may be available
in the server error log.</p>
</body></html>

Httpd error logs show this error?

Any suggestions would be greatly appreciated!

Update:

Attempted to get around this by removing this line:

sys.path.append('/home/user/Path/to/')

And instead creating a symlink to the module in /var/www/cgi-bin/ which appears to work but my module accesses the folder /home/user/Path/to/folder which is throwing an access denied error in httpd logs.

Update:

Got this working using Django instead. It is, however, still a mystery to me why this wont work using Apache?
