Albert,

Thanks a million for script,

It worked fine after I closed the bracket.


import glob, codecs, re, os

regex = re.compile(r"Age: |Sex: |House No:  ") # etc etc

for txt in glob.glob("D:/Python/source/*.txt"):
    with codecs.open(txt, encoding="utf-8") as f:
        oldlines = f.readlines()
    for i, line in enumerate(oldlines):
        if "Elector's Name:" in line:
            break
    newlines = [regex.sub("", line).strip().replace("-", "_") for line in
oldlines[i:]]
    with codecs.open(txt + "_out.txt", "wb", encoding="utf-8") as w:
        w.write(os.linesep.join(newlines))


This program is not deleting the empty lines containing blank characters.
Kindly do the needful.
