Find all CSV files in a directory using Python

Question

How can I find all files in directory with the extension .csv in python?

Answer 1

By using the combination of filters and lambda, you can easily filter out csv files in given folder.

import os

files = os.listdir("/path-to-dir")    
files = list(filter(lambda f: f.endswith('.csv'), files))

# lambda returns True if filename name ends with .csv or else False
# and filter function uses the returned boolean value to filter .csv files from list files.
