Question :
How do I detect whether sys.stdout is attached to terminal or not? [duplicate]
Is there a way to detect whether sys.stdout is attached to a console terminal or not? For example, I want to be able to detect if foo.py is run via:
$ python foo.py # user types this on console
OR
$ python foo.py > output.txt # redirection
$ python foo.py | grep .... # pipe
The reason I ask this question is that I want to make sure that my progressbar display happens only in the former case (real console).
Answer #1:
if sys.stdout.isatty():
# You're running in a real terminal
else:
# You're being piped or redirected
