Is short-circuiting in assignment statements considered good style?

Question

If I understand correctly

myvar = a and b or c

gives the same result as

if a:
  if b:
    myvar = b
  else:
    myvar = c
e         


        

Answer 1

This is really an opinion question, but for the most part, the answer is no. It goes against multiple style guides, probably because people tend to think it means "if a is true, use the value of b, otherwise use the value of c" rather than the real meaning, which is what you posted.

You probably want the new-ish conditional expression syntax instead:

myvar = b if a else c
