Error trying to run first python script on IIS

Question

I followed the steps in a respose to how to Set up Python for IIS : Python on IIS: how?

But when I write my script and try running it it fails on the first line. I get this error message:

HTTP Error 502.2 - Bad Gateway The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are " File "C:\Development\Python\helloworld.py", line 1 print 'Content-Type: text/plain' ^ SyntaxError: invalid syntax ".

This is my frist attempt at python. What is going wrong?

Which python version did you use? If you're on python 3, you need parentheses: e.g., print('Content-Type: text/plain') — Ian Stapleton Cordasco

yes it is 3. So is it every print statement needs brackets? what's the syntax changes with 3? — greektreat

3

So your example helloworld.py needs to be changed to:

print('Content-Type: text/plain')
print('')
print('Hello, world!')

Python 3 changed print to use function call syntax (which can be used in python 2).

It works for me just using: print() at the top of my code, I did not need to use print('Content-Type: text/plain')
