This example describes how to implement the regular expression deletion command in Python programming. We will share this with you for your reference. The details are as follows:

Script purpose:

The del function arrow is used in DOS. The regular expression function is not supported.

Script implementation:

Import shutilimport OS, sys, redef remove_file (fname): mode = sys. argv [1] mode = mode. replace (". ","\\. ") if not re. search (mode, fname): return print "del... % s "% (fname) if OS. path. isfile (fname): OS. system ("del % s" % (fname) else: shutil. rmtree (fname) L = [x for x in OS. listdir (OS. getcwd ()] map (remove_file, L)
