I have a python web form with two options – File upload and textarea. I need to take the values from each and pass them to another command-line program. I can easily pass the file name with file upload options, but I am not sure how to pass the value of the textarea.
I think what I need to do is:
Generate a unique file name
Create a temporary fil….

How can I tell if a file is binary (non-text) in Python?
I am searching through a large set of files in Python, and keep getting matches in binary files. This makes the output look incredibly messy.
I know I could use grep -I, but I am doing more with the data than what grep allows for.
In the past, I would have just searched for characters greate….
I have a program which writes a user’s highscore to a text file. The file is named by the user when they choose a playername.
If the file with that specific username already exists, then the program should append to the file (so that you can see more than one highscore). And if a file with that username doesn’t exist (for example, if the user is ….
How do I limit os.walk to only return files in the directory I provide it?

I try to copy a file with pathlib
import pathlib
import shutil
my_file=pathlib.Path(‘/etc/hosts’)
to_file=pathlib.Path(‘/tmp/foo’)

Currently I’m using this:
f = open(filename, ‘r+’)
text = f.read()
text = re.sub(‘foobar’, ‘bar’, text)
f.seek(0)
f.write(text)
f.close()
But the problem is that the old file is larger than the new file. So I end up with a new file that has a part of the old file on the end of it.

I am trying to load and parse a JSON file in Python. But I’m stuck trying to load the file:
