Removing leading\trailing spaces

[deanhystad]

Or you could use an iterator and next.

# Read in all the lines
delim = ","
with open("data.csv", "r") as file:
    lines = iter(list(file))

with open("data.txt", "w") as file:
    # Strip spaces in header row
    file.write(",".join(map(str.strip, next(lines).split(delim)))+"\n")
    file.writelines(lines)  # Copy other lines unchanged

Why do you want to leave spaces in the rest of the file?
