from __future__ im         


        

Answer 1

You have split your lines into columns:

parts = (line.split(',') for line in f)

then try to strip each list of columns:

column = (part.strip() for part in parts)

That won't work. Strip each column instead:

column = ([col.strip() for col in part] for part in parts)

You may want to use the csv module to do the transformation from file to row-of-data instead however:

with open("/home/mic/tmp/test.txt", 'rb') as f:
    reader = csv.reader(f, skipinitialspace=True)
    for object_ in iter_something(reader):
        print(object_)

The skipinitialspace option makes sure that a space directly following the delimiter is removed. A newline at the end of each line removed as a matter of course.

Answer 2

parts = (line.split(',') for line in f) strip when you split as you are creating lists with split:

parts = (line.strip().split(',') for line in f)
