The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
This problem often comes up in compiler construction, especially scannerless parsing.The convention when dealing with the dangling else is to attach the else to the nearby if statement, [2] allowing for unambiguous context-free grammars, in particular.
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
[3] In the Parsons problem exam question, the first example shown, there are 6 pairs of statements, one mark is deducted for each incorrectly chosen line from the pairs, two marks are deducted if more than 2 lines are out of place, and one mark is deducted if up to two things are out of place.
Since 7 October 2024, Python 3.13 is the latest stable release, and it and, for few more months, 3.12 are the only releases with active support including for bug fixes (as opposed to just for security) and Python 3.9, [55] is the oldest supported version of Python (albeit in the 'security support' phase), due to Python 3.8 reaching end-of-life.

Yet ‘Grand Theft Auto’ might be an oddly appropriate venue for a play where nearly everyone dies.”
Software developer Katrina Owen created Exercism while she was teaching programming at Jumpstart Labs. [6] The platform was developed as an internal tool to solve the problem of her own students not receiving feedback on the coding problems they were practicing.
