I have this code:
class CleanUp:
def __init__(self,directory):
self.directory = directory
def del_items(self,*file_extensions):
"""deletes specified file extensions in specificied directory"""
removed_files = [file for file in os.listdir(self.directory) for ext in file_extensions if ext in file]
for index ,file in enumerate(removed_files):
print(str(index + 1) + ": " + file + "\n")
confirm_delete = input("are you sure you want to delete all {0} files? y|n ".format(len(removed_files)))
while confirm_delete.lower() not in ("y","n"):<--------- this while loop
confirm_delete = input("are you sure you want to delete all {0} files? y|n ".format(len(removed_files)))
if confirm_delete.lower() == "y":
for file in removed_files:
try:
os.remove(os.path.join(self.directory,file))
except:
pass
print("successfully deleted {0} files".format(len(removed_files)))
else:
print("deletion cancelled goodbye")
pass
directory = input("please enter a directory ")
while not os.path.exists(directory):
print("{0} is not a valid directory \n".format(directory))
directory = input("please enter a directory ")
file_extensions = input("please put in file extensions of files that need deleting. seperate them by one space ")
file_extensions = file_extensions.split()
desktop = CleanUp(directory)
deleted_files = desktop.del_items(*file_extensions)
This line works
while confirm_delete.lower() not in ("y","n"):
however, when I try to do
while confirm_delete.lower() != "y" or confirm_delete.lower() != "n":
the while loop never passes.
I'm sure it has something to do with the or but
why doesn't it work when done like that?
