importing CSV file into a HTML table using Python

[scidam]

Probably, you forgot something like this:

print("<tr>")
print("\n".join("<td>%s</td>" % v for v in row))
print("</tr>")

instead of lines 30-42.

However, I would strongly recommend to look (and use it) at some template engine (e.g. jinja2), if you want
to generate html/xml/text etc. formatted documents.
