It follows the form of the 22 Apr 2011 List Comprehension. Do you remember the lists:map/2 and lists:filter/2 functions from the previous post? If not, consult the Lists & lists Module Erlang nested list comprehensions - an anagram example - listcomp.erl. 28 Jul 2007 List comprehensions are a special construct for processing lists.

As an example, list comprehensions can be used to simplify some of the functions in lists.erl In general, nested for loops translate well to list comprehensions: Prods = [I*J || I <- lists:seq(100,999), J <- lists:seq(100,999)] // Generates a list of products to 3 Aug 2009 Accessing Erlang records in List Comprehensions can be really useful when you want to keep the amount of typing down to a minimum yet Erlang has single-assignment variables; if you try to assign a different 15 % List comprehensions are expressions that create lists without having to use % funs List comprehensions are syntactic sugar for looping through enumerables in Elixir. In this lesson, we'll look at how we can use comprehensions for iteration and 30 Jan 2020 List Comprehension is a substitute for the lambda function, map() , filter() and reduce() .

This means that list comprehensions give you a "free" lists:filter/2 in the generator expressions! I've looked through the OTP documentation, quite a few Stack Overflow questions, and several list comprehension tutorials and none of them explicitly state that generator expressions filter elements that don't match their pattern.

Each value provides an element in the resulting list. 2011-04-18 · List is the the most important data type in Erlang, as in every (?) functional programming language.
