python - Is it okay to put error-prone code in an OR statement? -

-

this in python, can applied language.

a = none if (not a) or (a+3==5):     print("is okay?")

is programming practice have a+3 in if statement, though cause error if a none?

i'm relying on or stop before error, seems bad idea me in case a else doesn't support addition, or or statement (in other language) looks @ both values.

what best way program this?

yes can depend on short-circuiting perform error handling , validation.

however in case, logic wrong, need and perform error handling

if , (a+3==5):

alternatively type checking

if isinstance(a, int) , (a+3==5):

again short-circuit before reading + operation
