python - 在 Python 中删除 csv 文件中的空白行

Question

我在一个文件夹中有一些 csv 文件，我正在尝试删除所有空白行并将新闻文件移动到一个新文件夹中。

这是我的代码：

import csv
import glob
import os
import shutil

path = 'in_folder/*.csv'
files=glob.glob(path)

#Read every file in the directory

x = 0 #counter

for filename in files:

    with open(filename, 'r') as fin:
        data = fin.read().splitlines(True)

        with open(filename, 'w') as fout:
            for line in fin.readlines():
                if ''.join(line.split(',')).strip() == '':
                    continue
                fout.write(line)
            x += 1            


dir_src = "in_folder"
dir_dst = "out_folder"


for file in os.listdir(dir_src):
    if x>0:
        src_file = os.path.join(dir_src, file)
        dst_file = os.path.join(dir_dst, file)
        shutil.move(src_file, dst_file)

代码现在正在做的是从文件中删除所有内容并将它们移动到新文件夹中。我希望我的文件相同，但删除了空白行。

您可以将每一行输出到新文件，之后无需进行任何移动：

dir_src = "in_folder/*.csv"
dir_dst = "out_folder"

files = glob.glob(dir_src)

# Read every file in the directory

x = 0 # counter

for filename in files:
    outfilename = os.path.join(dir_dst, os.path.basename(filename))
    with open(filename, 'r') as fin:
        with open(outfilename, 'w') as fout:
            for line in fin:
                if ''.join(line.split(',')).strip() == '':
                    continue
                fout.write(line)
            x += 1
