[1] the environment is a mapping associating each free variable of the function (variables that are used locally, but. In other words, it copies a value into the variable For example, an auxiliary variable may be defined in a block, then used (say, added to a variable with function scope) and discarded when the block ends, or a while loop might be enclosed in a block that initializes variables used inside the loop that should only be initialized once.

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. Variable shadowing in computer programming, variable shadowing occurs when a variable declared within a certain scope (decision block, method, or inner class) has the same name as a variable declared in an outer scope
At the level of identifiers (names, rather than variables), this is known as name masking. 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 metasyntactic variable is a specific word or set of words identified as a placeholder in computer science and specifically computer programming
