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. String functions are used in computer programming languages to manipulate a string or query information about a string (some do both) Here documents can be treated either as files or strings Some shells treat them as a format string literal, allowing variable substitution and command substitution inside the literal. In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
A string literal or anonymous string is a literal for a string value in source code In many languages, the text foo is a string literal that encodes the text foo but there are many other variations. A basic example of string searching is when the pattern and the searched text are arrays of elements of an alphabet (finite set) σ.
