Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. 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 ...
In mathematics, a tuple is a finite sequence or ordered list of numbers or, more generally, mathematical objects, which are called the elements of the tuple. An n-tuple is a tuple of n elements, where n is a non-negative integer. There is only one 0-tuple, called the empty tuple. A 1-tuple and a 2-tuple are commonly called a singleton and an ...
Python's isoperator may be used to compare object identities (comparison by reference), and comparisons may be chained—for example, a<=b<=c. Python uses and, or, and notas Boolean operators. Python has a type of expression named a list comprehension, and a more general expression named a generatorexpression.
Similarly, the idea of immutable data from functional programming is often included in imperative programming languages, for example the tuple in Python, which is an immutable array, and Object.freeze() in JavaScript. Comparison to logic programming
In mathematics, an ordered pair ( a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair ( a, b) is different from the ordered pair ( b, a) unless a = b. (In contrast, the unordered pair { a, b } equals the unordered pair { b, a }.) Ordered pairs are also called 2-tuples, or sequences ...
A deterministic finite automaton M is a 5- tuple, (Q, Σ, δ, q0, F), consisting of. a finite set of states Q. a finite set of input symbols called the alphabet Σ. a transition function δ: Q × Σ → Q. an initial or start state q 0 ∈ Q {\displaystyle q_ {0}\in Q} a set of accept states F ⊆ Q {\displaystyle F\subseteq Q}

List (abstract data type) In computer science, a list or sequence is collection of items that are finite in number and in a particular order. An instance of a list is a computer representation of the mathematical concept of a tuple or finite sequence. A list may contain the same value more than once, and each occurrence is considered a distinct ...
