The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19] The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir
US News & World Report released a list of the cities with the best quality of life for 2024 to 2025. Cities with places for outdoor activities, such as beaches and mountains, ranked higher.
The next time you're at a shelter, consider the dogs that need help the most. They need love! Like Ollie, a German Shepherd mix who seems to have "lost all hope" about finding a forever home.
Python's is operator 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 not as Boolean operators. Python has a type of expression named a list comprehension, and a more general expression named a generator expression. [78]
Life expectancy in the United States is rising nearly as quickly as it fell at the start of the Covid-19 pandemic as deaths from Covid-19 and drug overdoses drop.
