I am trying to do some list comprehension in F#. And I found this. let evens n = { for x in 1 .. n when x % 2 = 0 -> x }
So, I was looking at the question here, and built a rather ugly solution for the problem.While trying to clean it up, I started investigating list comprehensions and the list monad.What I decided to d
I have a list of lists (generated with a simple list comprehension): >开发者_StackOverflow中文版;>> base_lists = [[a, b] for a in range(1, 3) for b in range(1, 6)]
This seems like a common task, alter some elements of an array, but my solution didn\'t feel very pythonic. Is there a better way to build urls with list comprehension?
I amdoing problem 68 at project euler and came up with the following code in Haskell to return the list of numbers which fit the (given) solution:
Is there a pythonic way to build up a list that contains a running average of some function? After reading a fun little piece about Martians, black boxes, and the Cauchy distribution, I thought it wo
I\'ve heard that list comprehensions can be slow sometimes, but I\'m not sure why? I\'m new to Python (coming from a C# backgrou开发者_Python百科nd), and I\'d like to know more about when to use a lis
When I do the following list comprehension I end up with nested lists: channel_values = [x for x in [ y.split(\' \') for y in
Can I use list comprehension syntax to create a dictionary? For 开发者_如何学编程example, by iterating over pairs of keys and values:
I wa开发者_StackOverflow社区nt to do something like: all = [ x for x in t[1] for t in tests ] tests looks like:
