Interpreting Left to right?

[Chetan Harjani]

Now its all clear. Thanks
@ethan .. ur example is really scary.
I didnt understand ur example fully although.
See this is what i take it as:
x=x['huh']={}

>first python checks check that there are two = operators.
>so it evaluates the RHS(since for = it is RHS to LHS) experession of right
most (why is that?)
>now it assigns that experrsion({...}) to x the left most as u said first
RHS to LHS then LHS to RHS.
>then it assigns x to to x['huh'].
huh!!, ryt?
may be it doesnt make sense but i guess this is the only way to actually not
raise an error.

Where am I wrong?
