Internal server error with simple .cgi, what is wrong?

I'm in internet programming, and we are doing .cgi, but for the life of me, I cannot get my .cgi script to run at all, I know other people have it working, but mine just refuses to run. Any suggestions?

#!/usr/bin/env python

print "Content-type: text/html"
print
print "<html><head><title>CGI</title></head>"
print "<body>"
print "hello cgi"
print "</body>"
print "</html>"

I have chmod 755 the file multiple times, i have tried using #!/usr/bin/python and #!usr/local/bin/python. I tried putting it in a folder named cgi-bin and I've made sure that it is saved with unix line endings, but all I ever get is internal server error. I know I had it working in class, but now it just refuses to run, any help guys? Thanks?

The only way you're going to find out for sure is to look in the server logs. They're in different places on different operating systems, so I can't tell you where to look. Find the logs and you will find an error message explaining exactly why a 500 is being returned. - Jim Garrison
well i'm on Ubuntu, and the server is running apache on CentOS, does that help? - convergedtarkus
on the centos server check the apache logs. They should be at: /var/log/httpd/error_log - monkut

Wild guess: you are using Python 3, so your print statements have to be print function calls:

print("Content-type: text/html")
etc...

Ok, this is a really easy fix that I totally missed. First off Ned Batchelder correctly pointed out that my code is python 2 (which is weird since I use python 3) but the problem is the print statement after the, print("Content-type: text/html"). The second print statement has to be print("") not just print(). So i feel a little stupid, but that fixed the issue for me, hope this helps someone else!
