What does that mean? Did you get an error message? If so what?
Was the file empty? What happened? Be specific.
a way around this, other than passing the file as I have here?
Passing the file object around is good, its not "a way around".
Its what you should be doing. Passing objects into functions and getting
a result back is what good programming encourages.
Leaking objects across function boundaries from the outside
(eg with global variables) is bad and should be avoided.
Since this is a file there are enclosing single quotes not visible:
I don't know what you mean by that.
What is a file? The data below?
Why would that put it in enclosing quotes?
"ANTIGUA AND BARBUDA",0,0,0,0,0
"ARGENTINA",37,35,33,36,39
"BAHAMAS, THE",1,1,1,1,1
"BAHRAIN",5,6,6,6,6
"SPANISH INQUISITION, THE, SILLY",10,33,14,2,8
Program follows (py3.4, winxp):'''
htbegin = '''
...

htend = '''

def make_lines():
co2 = open('co2-sample.csv')
ht = open('output.html', 'w')
linelist = []
print(htbegin, file=ht)
Why not just write to the file directly?
ht.write(htbegin)
for line in co2:
newlist = line.rsplit(',', 5) # ending is regular so split it out
first
for token in newlist: # since split char inside quotes for
nation is problematic
Use the csv file to parse csv files, it is much more reliable and avoids
all the strange exceptional cases such as embedded commas,
split lines etc.
linelist.append(token.strip('"')) # get rid of extra quotes
linelist[-1] = linelist[-1].strip()
fprint(linelist, ht)
linelist = []
I don't think resetting the list adds much value?
co2.close()
print(htend, file=ht)
ht.write(htend)
ht.close()
def fprint(linelist, ht):
# size formatting irrelevant for HTML
formatted_string = "<td
class=l>{}</td><td>{}</td><td>{}</td><td>{}</td><td>{}</td><td>{}</td>".format(*linelist)
your table has no rows, is that deliberate? I'd expect a <tr> at the
beginning...
print(formatted_string, file=ht)
ht.write(formatted_string)
print('</tr>', file=ht)
and now you add a </tr> at the end. Why not just put it
inside the string?
