您可以使用 pandas 将 CSV 文件作为数据帧读取，从每个文件中获取 link 列，然后将结果写入文本文件。试试这个：
from os.path import abspath, join
from os import listdir
import pandas as pd
abs_path = abspath(path) # path of your folder
for filename in listdir(abs_path):
df = pd.read_csv(join(abs_path, filename), usecols=['link'])
df.to_csv(filename +'.txt', header=None, index=None, sep=' ', mode='w')
注意：列名称（至少链接列）必须明确出现在所有文件中。
You can use pandas to read your CSV files as dataframes, get the link column from each file then write the result in a text file. Try this :
from os.path import abspath, join
from os import listdir
import pandas as pd
abs_path = abspath(path) # path of your folder
for filename in listdir(abs_path):
df = pd.read_csv(join(abs_path, filename), usecols=['link'])
df.to_csv(filename +'.txt', header=None, index=None, sep=' ', mode='w')
Note : columns names (at least link column) must be present explicitly in all files.
