RE: who is Barry? - Skaperen - Nov-13-2021
why is
!= bad?
RE: who is Barry? - Gribouillis - Nov-13-2021
Since the beginning of python, one could write != or <> for the "not equal" comparison operator. See for example the Python 2.4 comparison operators where <> is already marked as obsolescent. It disapeared somewhere along the way. Barry Warsaw is said to prefer <>.
RE: who is Barry? - Skaperen - Nov-14-2021
i've always preferred
!= because it was IMHO clearer in meaning and made code somewhat easier to read. i recall this was an issue in a prior language i encountered but i cannot remember which language it was. it was not Fortran.

Barry was one of the early users of Python and he is still involved with Python.
You might want to look at PEP 0401 ( https://www.python.org/dev/peps/pep-0401/ ).
RE: who is Barry? - Skaperen - Nov-17-2021
i was reading PEP 8 just a while ago and noticed his name there.
i like PEP 401. i'm all for abandoning C and avoiding C++ and Objective-C for the base compiler and using just Python for everything. i'm waiting for PythOS.
