使用python删除多个csv文件的内容

Question

I am using the following code to delete the content of a single csv file:

filename = "output.csv"
# opening the file with w+ mode truncates the file
f = open(filename, "w+")
f.close()

Is there a way to this at the same time to multiple csv files which are in the same folder? Basically I want to keep the filenames and only to delete their content.

You can use the glob package in the standard library to get a list of files by extension in a directory:

import glob

for csv_file in glob.glob("*.csv"):
    open(csv_file, "w+").close()
