If Python does not have a ternary conditional operator, is it possible to simulate one using other language constructs?

Think of the conditional expression as switching between two values. It is very useful when you're in a 'one value or another' situation, it but doesn't do much else.

If you need to use statements, you have to use a normal if statement instead of a conditional expression.

Keep in mind that it's frowned upon by some Pythonistas for several reasons:

  • The order of the arguments is different from those of the classic condition? a: b ternary operator from many other languages (such as C, C++, Go, Perl, Ruby, Java, Javascript, etc.), which may lead to bugs when people unfamiliar with Python's "surprising" behavior use it (they may reverse the argument order).
  • Some find it "unwieldy" since it goes contrary to the normal flow of thought (thinking of the condition first and then the effects).
  • Stylistic reasons. (Although the 'inline if' can be really useful, and make your script more concise, it really does complicate your code)
