Hi there,
Pretty new to python I've got a question regarding the proper shebang
for Python 3.
I use
#!/usr/bin/python3
which works fine.
Today I saw
#!/usr/bin/python3 -tt
and was wondering what -tt means.
Being on Fedora 30, Python 3.7.3 the man page of python3 doesn't even
mention -t.
python 2 man page mentions
-t Issue a warning when a source file mixes tabs and spaces
for indentation in a way that makes it depend on the worth
of a tab expressed in spaces. Issue an error when the option is
given twice.
I guess that -t has the same meaning with python 3.7.3.
My questions:
1. Is my guess correct?
2. Is it a bug that it is not mentioned? python3 --help doesn't mention
it either.
