Database executable program fragments can be written using the monad comprehension notation [2] and list processing combinators from the Haskell list prelude. Note that rather than embedding a relational language into Haskell, we turn.

In Haskell we call these List Comprehensions. For starters we can do this same set, but in Haskell. In Haskell we would use the notation [x*2 | x <- [1..10]]. From this equation you can see.

Using list comprehension to loop through a string in Python, it’s possible to convert strings from lower case to upper case, and vice versa. Making use of Python’s lower() and upper() methods, we’ll use list comprehension to achieve this common task. Example 6: Changing a.

In Haskell, a similar comprehension notation can be used to construct new lists from old lists.A string is a sequence of characters enclosed in double quotes. Internally, however, strings are Similarly, list comprehensions can also be used to define functions on strings , such counting how.Idiom #53 Join a list of strings .Concatenate elements of string list x joined by the.

Answer (1 of 3): The way Travis Hance mentioned is the best way to think about list comprehensions. The report does not mandate an exact desugaring however—it just has to be.

List Comprehensions • The syntax of a list comprehension is somewhat tricky [x-10 for x in grades if x>0] • Syntax suggests that of a for-loop, an in operation, or an if statement • All three of these keywords (‘for’, ‘in’, and ‘if’) are also used in the syntax of forms of list comprehensions.

List comprehensions are reportedly adopted from Haskell [docs.python.org] (although mathematical set theory is their original source; Haskell’s comprehension uses mathematical set theory notation and syntax). Perhaps the ‘Functional Programming only’ model of list comprehension is simply carrying over from Haskell.
