- Conditional (computer programming) - Wikipedia
Conditional (computer programming) If-then-else flow diagram A nested if–then–else flow diagram In computer programming, a conditional statement directs program control flow based on the value of a condition; a Boolean expression A conditional expression evaluates to a value without the side-effect of changing control flow
- Python syntax and semantics - Wikipedia
Python syntax and semantics A snippet of Python code demonstrating binary search The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers) The Python language has many similarities to Perl, C, and Java
- Dangling else - Wikipedia
Dangling else The dangling else is a problem in programming of parser generators in which an optional else clause in an if–then (–else) statement can make nested conditional statements ambiguous Formally, the reference context-free grammar of the language is ambiguous, meaning there is more than one correct parse tree
- Control flow - Wikipedia
Python supports conditional execution of code depending on whether a loop was exited early (with a break statement) or not by using an else-clause with the loop
- Short-circuit evaluation - Wikipedia
Note that there are more short-circuit operators, for example the ternary conditional operator, which is cond ? e1 : e2 (C, C++, Java, PHP), if cond then e1 else e2 (ALGOL, Haskell, Kotlin, Rust), e1 if cond else e2 (Python)
- Structured programming - Wikipedia
Structured programming is a programming paradigm characterized by source code that uses block -based source code structure to encode control flow such as sequence, selection (i e if-then-else and switch) and iteration (i e for and while)
- If and only if - Wikipedia
This is an example of mathematical jargon (although, as noted above, if is more often used than iff in statements of definition) The elements of X are all and only the elements of Y means: "For any z in the domain of discourse, z is in X if and only if z is in Y "
- Multiway branch - Wikipedia
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria It is a form of conditional statement A multiway branch is often the most efficient method of passing control to one of a set of program labels, especially if an index has been created beforehand from the raw data
