Hi
I have a fileobject which was fine however now I want to delete a line from the
file object before yielding.
def return_files(file_list):
for filename in sorted(file_list):
When joining paths together, it's better to use 'os.path.join'.
with open(dir_path + filename) as fd:
for fileItem in fd:
yield fileItem
Ned gave an answer over here http://stackoverflow.com/a/6985814/461887
for i, line in enumerate(input_file):
if i == 0 or not line.startswith('#'):
output.write(line)
which I would change because it is the first line and I want to rid <!--
for i, line in enumerate(input_file):
if line.startswith(<!--'):
output.write(line)
However I do not want to write the file I want to restore all the enumerated
files back to the fileItem I need to yield.
How do I do this?
You use the logic of the answer from StackOverflow in your
'return_files' function:
def return_files(file_list):
for filename in sorted(file_list):
with open(dir_path + filename) as fd:
for fileItem in fd:
if keep_item(fileItem):
yield fileItem
If you need to know the line number when deciding whether to keep a
line, use enumerate too:
def return_files(file_list):
for filename in sorted(file_list):
with open(dir_path + filename) as fd:
for i, fileItem in enumerate(fd):
if keep_item(fileItem, i):
yield fileItem
