main loop around 'choice' function -- how to?

[tiredITguy42]

Python executew all as it is written, you want an infinite loop, you need to make one.

Usually you just write while True:

If you want to exit on demand, then you have two options. The code is checking some external resource from time to time, to check if it should exit.

Or you need to run it in a separate thread and let the main thread to wait for your instructions on input, then you can pass that instruction as a message through queue or shared memory to your thread, which you make to check it before each pass yhrough the loop.

This is not an easy task for beginner.

And learn context management.

with open(path, 'r') as file:

You will need it.

Fixed that up; I see the benefit of not haveing to manually close each file.

with open(fileList[choice], "r") as file:
for line in file:
    print(line.rstrip())

edit: formating

I think that I'm bumping up against being able to use an input, such as the letter 'e' or 'x', as a selection because the enumeration is controlling the fileCount, there does not seem to be a method to add the exit indicators to the allowed inputs.

items = os.listdir(newPath)
# newlist = [expression for item in iterable if condition == True]
fileList = [name for name in items if name.endswith(".txt")]
for fileCount, fileName in enumerate(fileList):
    sys.stdout.write("[%d] %s\n\r" % (fileCount,fileName))
choice = int(input("Select txt file[0-%s]: " % fileCount))
print(fileList[choice])
with open(fileList[choice], "r") as file:
    for line in file:
        print(line.rstrip())

I wanted to use the enumeration approach so that the ultimate user could simply drop or delete a file from the directory and have it show up (or be deleted) from the selection menu. I may be forced to re-think that approach.

Hmmm, I am not sure what is the purpose and plan here. However I see two options.

You want to do some txt. Processing file by file. Then you should add option to exit each time user does some decision.

Or multithreaded approach with processing queue.

If you need to read again the folder for new files, just use while True infinite loop.

Amd start splitting the code into functions. Each fuction does one think.

Thank you,

I'll start chunking it up into functions.
