In that case, please never insult the intelligence of your future
readers by including any of these parentheses:

x = 1 + (2 * 3)
value = 77 if (x % 2) else (70*7)

And if your readers have to figure out what 3**3**3 is interpreted as,
there should be an interactive interpreter around. Or here - try
something cute:

>>> 2**2**-1
