Write a list of the contents of the current directory to a csv file in Python.

dirlister

import glob
# glob does regular expression pattern matching, expansion etc, and, it returns
# a list of strings - nice and easy to work with

  
# List files starting with anything and ending with anything:
# glob.glob("*.*")
#
# to list only text files, for example, try:
# glob.glob("*.txt")
#
# or, for pdfs try:
# glob.glob("*.pdf")

# Store list of directories contents to a variable (globlet)
globlet = glob.glob("*.*")
# get the length of the variable for determining when to stop adding
# commas to our resulting comma-separated file
globletSize = len(globlet)

# open an appropriately named file for writing, 
# and then use the csv module to create the output
# in said file!
#
# Note, if you want to have quotes around each element of the list
# use the following syntax:
# w = csv.writer(file, quoting=csv.QUOTE_ALL)

with open('outfile.txt', 'w') as file:
  w = csv.writer(file, quoting=csv.QUOTE_NONE)
  w.writerow(globlet)
