doublequote bool(x) -> bool
escapechar
quotechar str(object) -> string
quoting int(x[, base]) -> integer
skipinitialspace bool(x) -> bool

__call__(lines)[source] [edit on github]

Return an iterator over the table lines, where each iterator output is a list of the split line values.

Parameters:lines – list of table lines
Returns:iterator
join(vals)[source] [edit on github]
process_line(line)[source] [edit on github]

Remove whitespace at the beginning or end of line. This is especially useful for whitespace-delimited files to prevent spurious columns at the beginning or end. If splitting on whitespace then replace unquoted tabs with space first
