Not necessarily better, but instead of passing around the file you can
rewrite your code to use generators:
import csv
def make_lines():
with open('co2-sample.csv') as co2:
yield htbegin
for linelist in csv.reader(co2):
yield from fprint(linelist)
yield htend
def fprint(linelist):
yield ("<td class=l>{}</td><td>{}</td><td>{}</td>"
"<td>{}</td><td>{}</td><td>{}</td>\n").format(*linelist)
yield '</tr>\n'
if __name__ == "__main__":
with open('output.html', 'w') as ht:
ht.writelines(make_lines())
Python versions before 3.3 don't understand
yield from fprint(linelist)
You have to write
for s in fprint(linelist):
yield s
instead.
