This is a very popular pattern in python where you'd introduce _variable before the evalution so:

if (user.id < 4 and user.session): ...

# you'd do

_user_has_access = (user.id < 4 and user.session) if _user_has_access: ...

# or even walrus

if _user_has_access := (user.id < 4 and user.session): ...

One of my coworkers really liked this pattern and his code was always so easy to read and to this day I'm carrying this torch!
