我有很多文本文件，每个文件最后都有一个空行。我的脚本似乎没有删除它们。有人可以帮忙吗？

# python 2.7
import os
import sys
import re

filedir = 'F:/WF/'
dir = os.listdir(filedir)

for filename in dir:
    if 'ABC' in filename: 
        filepath = os.path.join(filedir,filename)
        all_file = open(filepath,'r')
        lines = all_file.readlines()
        output = 'F:/WF/new/' + filename

        # Read in each row and parse out components
        for line in lines:
            # Weed out blank lines
            line = filter(lambda x: not x.isspace(), lines)

            # Write to the new directory 
            f = open(output,'w')
            f.writelines(line)
            f.close()
