Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
This list includes SQL reserved words – aka SQL reserved keywords, [1] [2] as the SQL:2023 specifies and some RDBMSs have added. Reserved words in SQL and related products In SQL:2023 [ 3 ]
Python list comprehensions (such as [x*x for x in range(10)] for a list of squares) and decorators (such as @staticmethod). In Haskell, a string, denoted in quotation marks, is semantically equivalent to a list of characters. An optional language extension OverloadedStrings allows string literals to produce other types of values, such as Text ...
ToList: Creates a List<T> from the collection. ToDictionary: Creates a Dictionary<K, T> from the collection, indexed by the key K. A user supplied projection function extracts a key from each element. ToLookup: Creates a Lookup<K, T> from the collection, indexed by the key K. A user supplied projection function extracts a key from each element.
Files are similar to tables in a relational database in that each file has a unique name to distinguish it from other files and zero to multiple unique records that are logically related to each other. Files are made of two parts: a data file and a file dictionary (DICT). The data file contains records that store the actual data.
In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values.
A metasyntactic variable is something that stands for another piece of text. For example, you should use a metasyntactic variable in the documentation of a function to describe the arguments that are passed to that function. Do not use @var for the names of particular variables in programming languages. These are specific names from a program ...
A dictionary is a map of a list of keys to a list of values. A table is a transposed dictionary of symbol keys and equal length lists (columns) as values. A keyed table, analogous to a table with a primary key placed on it, is a dictionary where the keys and values are arranged as two tables.
