Check if any file is existing else do the command
I'm given a task to detect if there is a file inside a path, if there is no file then sleep and wait until there is a file existing else do the command.
Here is my code
import os,time
path = 'C:\Users\test'
for dir, sub_dirs, files in os.walk(path):
while not files:
print("no files at this level")
time.sleep(1)
if files:
print("file detected")
Even I put the file inside the path, it keeps sleeping, it does not print file detected, What is wrong with this?

files won't change in the while loop. You'll have to os.walk again.
import os,time
def file_exists(path):
for dir, sub_dirs, files in os.walk(path):
return files
path = r'C:Userstest'
while True:
if file_exists(path):
print("file detected")
break
else:
print("no files at this level")
time.sleep(1)
Here we have an infinite loop. If a file is found we call break and exit the loop.
My first answer used a nested combination of while and for and the break only exited the inner loop, so that wasn't going to work.
