how set/change env var PYTHONOPTIMIZE in Python 3 / 3.7 / 3.8 ????

I want to skip assertion... how?

a = input("enter a number: ")

assert int(a) > 0 or int(a) < 0, "a is zero" # also a != 0

# https://docs.python.org/3/using/cmdline.html#envvar-PYTHONOPTIMIZE

"""
PYTHONOPTIMIZE
If this is set to a non-empty string it is equivalent to specifying the -O option. If set to an integer, it is equivalent to specifying -O multiple times.

You can change it like any environment variable in your OS (which is?) That said, why not simply run python with the -O option?

when you say:

What do you mean in Python IDLE or Thonny Python Editor? When running/executing the file.py... how?

Please give an example

With IDLE in python 3.8 it works for me if I open IDLE with the -O switch on the command line
Output:
python3.8 -O -m idlelib
It seems that idle propagates the -O flag to the scripts that it runs.

With Thonny, it didn't work with the -O flag, but it worked with this command line (in linux)
Output:
PYTHONOPTIMIZE=1 python3.8 -m thonny
