Many programming languages have a ternary operator, which define a conditional expression. The most common usage is to make conditional assignment terse simple conditional assignment statement. In other words, it offers one-line code to evaluate the first expression if the condition is true, otherwise it evaluates the second expression.

Moreover, the colon already has many uses in Python. So, conditional assignment, when PEP was approved, Python finally received its own shortcut conditional expression:. It first evaluates the condition; if it returns Trueexpression1 will be evaluated to give the result, otherwise expression2. Evaluation is lazy, so only one expression will be executed. Conditions are evaluated from left to right, which is easy to double-check with something like the pprint module:.

For Python versions lower then 2. They are generally discouraged, but it's good to know how they work:. The problem of such an approach is that both expressions will be evaluated no matter what the condition is, conditional assignment. As a workaround, lambdas can help:. Yes, most of the workarounds look ugly. Nevertheless, conditional assignment, there are situations when it's better to use and or or conditional assignment than the ternary operator.

For example, when your condition is the same conditional assignment one of expressions, you probably want to avoid evaluating it twice:.
