我正在使用 Blair 的 Python 脚本，它修改 CSV 文件以将文件名添加为最后一列（脚本附加在下面）。但是，我不是单独添加文件名，而是在最后一列中获取路径和文件名。
cmd我使用以下命令在 Windows 7 中运行以下脚本：
python C:\data\set1\subseta\add_filename.py C:\data\set1\subseta\20100815.csv
生成的 ID 字段由以下内容填充C:\data\set1\subseta\20100815.csv，但我只需要20100815.csv.
我是python的新手，所以任何建议都值得赞赏！
import csv
import sys
def process_file(filename):
# Read the contents of the file into a list of lines.
f = open(filename, 'r')
contents = f.readlines()
f.close()
# Use a CSV reader to parse the contents.
reader = csv.reader(contents)
# Open the output and create a CSV writer for it.
f = open(filename, 'wb')
writer = csv.writer(f)
# Process the header.
header = reader.next()
header.append('ID')
writer.writerow(header)
# Process each row of the body.
for row in reader:
row.append(filename)
writer.writerow(row)
# Close the file and we're done.
f.close()
# Run the function on all command-line arguments. Note that this does no
# checking for things such as file existence or permissions.
map(process_file, sys.argv[1:])
