It's better to put the strings into a list and then concatenate them in
one go:

output = ['<html><head>']
output.append('<title>My Page</title>')
output.append('</head><body>')
output.append('<h1>Powers of two</h1>\n<ol>')
for n in range(1, 11):
     output.append('<li>%s</li>' % (2 ** n))

output.append('</ol></body></html>')
print ''.join(output)
