Hello

I have a simple python script I am trying to execute but when I access the file I get a HTTP500 error. Do I have the wrong Python Shebang?

- The python file has the permissions: 7,5,5
- Following VlexoFrees advice I have looked at my .htaccess file & its empty so it cant be misconfigured(although maybe I need to configure it for python scripts?)
- I have looked at the CPanel error logs but the 500 error isn't documented, it does show/record errors if I try to access the cgi-bin dir, ie, I go to www.selectrecipes.tk/cgi-bin/
- The python file should simply print out: "test"

The file is here: http://www.selectrec...cgi-bin/test.py

The contents of the file are simply:

#!/usr/bin/python2.7
print "content-type: text/html \n\n"
print "test"

The path is

/usr/bin/python

Click your test link again and it works.

I am now unable to access/run the script main.py. The weird thing is that main.py contains exactly the same execution code as test.py, but when I access main.py I get a HTTP500 error? I have tested the file & it has no errors so it should execute. Why does this happen?

http://www.selectrec...cgi-bin/main.py

The contents of main are:

#!/usr/bin/python2.7
import sqlite3
print "Content-Type: text/plain\n\n"
print "Eli is awesome"
print sqlite3.connect("test.db")

"""#!/usr/bin/python2.7
import db.AutoBlogDatabase
print "content-type: text/html \n\n"
print "Worked"
d = db.AutoBlogDatabase.AutoBlogDatabase()
#d = db.Database.Database()
print "Worked" """

Same situation.

Replace:

#!/usr/bin/python2.7

with:

#!/usr/bin/python

This should be for all of the python scripts you write.

hmm, still doesn't work. I changed the shebang to just
#!/usr/bin/python
but its the same HTTP500 error. Python is great but one of the WORST languages get working on webhosts, its never easy with python scripts *sigh.

Also will the above shebang load python2.7? The module(sqlite3) I am using in that script is only foun in python 2.6 & up.

PS: I like to look of your blog

No, it loads 2.4. Calling 2.7 seemed pretty slow compared to the others when I tried it though.

You might want to try WSGI. I know that works.

Thanks mishmash!

I got it working!

It's to do with the encoding of the file. If I create a file on cpanel and cut & paste the exact same code from main.py into it then it works. I think the file needs to be utf-8. Weirdly only the file I am accessing has to be the correct encoding, if the file I am accessing imports other python files with incorrect encoding it still works.
