It is used to parse source code into concrete syntax trees usable in compilers, interpreters, text editors, and static analyzers. [1] [2] It is specialized for use in text editors, as it supports incremental parsing for updating parse trees while code is edited in real time, [3] and provides a built-in S-expression query system for analyzing ...
Python uses the following syntax to express list comprehensions over finite lists: S = [ 2 * x for x in range ( 100 ) if x ** 2 > 3 ] A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which ...

The SPARQL query processor will search for sets of triples that match these four triple patterns, binding the variables in the query to the corresponding parts of each triple. Important to note here is the "property orientation" (class matches can be conducted solely through class-attributes or properties – see Duck typing ).
UTM parameters in a URL identify the marketing campaign that refers traffic to a specific website. [1] To define and append the relevant UTM parameters to the appropriate URLs, marketers routinely use simple, spreadsheet-based, or automated UTM builder tools, [3] including the Google Analytics URL Builder for websites.

The Python Package Index appends the MD5 hash of a file to the URL as a fragment identifier. [31] If MD5 were unbroken (it is a broken hash function ), it could be used to ensure the integrity of the package.
