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. However, there are some ...
Dictionaries are represented as: { "key" = "value"; ... }. The left-hand side must be a string, but it can be unquoted. Comments are allowed as: /* This is a comment */ and // This is a line comment. As in C, whitespace are generally insignificant to syntax. Value statements terminate by a semicolon.
Pandas' syntax for mapping index values to relevant data is the same syntax Python uses to map dictionary keys to values. For example, if s is a Series, s['a'] will return the data point at index a. Unlike dictionary keys, index values are not guaranteed to be unique.
An INI file is a configuration file for computer software that consists of plain text with a structure and syntax comprising key–value pairs organized in sections. [1] The name of these configuration files comes from the filename extension INI, short for initialization, used in the MS-DOS operating system which popularized this method of software configuration.
Tom's Obvious, Minimal Language (TOML, originally Tom's Own Markup Language [2]) is a file format for configuration files. [3] It is intended to be easy to read and write due to obvious semantics which aim to be "minimal", and it is designed to map unambiguously to a dictionary.

Any existing mapping is overwritten. The arguments to this operation are the key and the value. Remove or delete remove a (,) pair from the collection, unmapping a given key from its value. The argument to this operation is the key. Lookup, find, or get find the value (if any) that is bound to a given key.
Trie-Find(x, key) for 0 ≤ i < key.length do if x.Children[key[i]] = nil then return false end if x := x.Children[key[i]] repeat return x.Value In the above pseudocode, x and key correspond to the pointer of trie's root node and the string key respectively.
