You mean something like
if 2 == x:
? I never write code like that, and I haven't seen it, either.
Just to this, I also never write code like that but I've certainly seen it
advocated.
I think the rationale was that it places the comparison value foremost in one's
mind, versus the name being tested. I'm not persuaded, but it is another
subjective situation.
It's sometimes advocated in C/C++ code to help catch the inadvertent use
of = instead of ==, but that's not a problem in Python.
