如何计算文本文件中的空白行数？

Question

import sys
import os
import glob
directory_input = raw_input("path to base directory?")
directory = directory_input

for folder in glob.glob(os.path.join(directory,"savedrecs(*).txt")):
    a = 0
    for file in glob.glob(os.path.join(folder, "savedrecs(*).txt")):
        a=sum(not line.strip() == "\n" for line in searchfile)
    print a

这是我的代码，但是 a=sum(not line.strip() == "\n" 部分不起作用，结果始终为零。

您永远不会打开文件，您的 glob 模式不会查找文件夹，它会查找文件，只需在用户定义的目录上 glob 一次，打开每个文件并 sum 次 not line.strip()计算结果为真：

import os
import glob
directory = raw_input("path to base directory?")


for fle in glob.glob(os.path.join(directory,"savedrecs*.txt")):
     with open(fle) as f:
         sm = sum(not line.strip() for line in f)
         print("{} has {} empty lines".format(fle, sm))
