Python CGI Script Error: End of script output before headers
Question
I'm getting an internal server error (500 err) "End of script output before headers" trying to run a cgi using
- XAMPP Apache on Windows
- Python 3.3
- Notepad++ with UNIX Style (\\n) newline chars
My script reads as follows
#!"C:\Python33\python.exe"
import cgi
def htmlTop():
print("Content-type: text/html")
print()
print("""<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>My Server Side Test</title>
</head>
<body>""")
def htmlTail():
print("""</body>
</html>""")
if ___name___ == "__main__":
try:
htmlTop()
print("Hello World")
htmlTail()
except:
cgi.print_exception()
Please note I have tried using print("Content-type: text/html\\n\\n") as opposed to the extra print statement. Thanks!

I know this is an old post but I found the errors in your script
The first mistake I found was the quote you used when requiring python,
so #!"C:\\Python33\\python.exe" should be changed to #!C:\\Python33\\python.exe
The second mistake I found was the additional bars you used
There are 3 bars here->___name___<-and here
so ___name___ should be changed to __name__
So the final code should be
#!C:\Python33\python.exe
import cgi
def htmlTop():
print("Content-type: text/html")
print()
print("""<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>My Server Side Test</title>
</head>
<body>""")
def htmlTail():
print("""</body>
</html>""")
if __name__ == "__main__":
try:
htmlTop()
print("Hello World")
htmlTail()
except:
cgi.print_exception()
