of CGI scripts, after all. Let’s start using this to better advantage now, and write a Python

Example 15-5. PP4E\Internet\Web\cgi-bin\tutor2.py

#!/usr/bin/python

print("""Content-type: text/html

for i in range(5):
print('

for j in range(4):
print('' % (i, j))
print('')

print("""

%d.%d

---

""")

Despite all the tags, this really is Python code—the tutor2.py script uses triple-quoted
strings to embed blocks of HTML again. But this time, the script also uses nested Python
