Why is this simple conditional expression not working? [duplicate]
You are using it wrong. Use it this way:
a = 2 if i in [1, 3, 6] else 7The general form is:
var = val1 if cond else val2
Should be
a = 2 if i in [1, 3, 6] else 7You can read it as:
a = (((2 if i in [1, 3, 6] else 7)))which is to say that the expression on the right side of the assignment sign is fully evaluated and the result then assigned to the left side. The expression itself is two values separated by the condition.
