Permute 2.2 For Macos

  1. This is why you can now schedule Permute to convert videos e.g. At night when you're not using your computer. And so much more! - There are so many other great features in Permute - adjust volume of an audio file or an audio track in a video. Batch-resize, rotate and flip images and videos. Compatibility: OS X 10.11 or later 64-bit.
  2. Permute offers easy-to-use drag-and-drop video conversion. Features: Easy to Use - built from the ground up, Permute is a perfect example of what a Mac app should be. With a gorgeous interface and drag & drop simplicity no need for complicated options. Insanely Fast - Permute was engineered to be incredibly fast. Let us take care of the hard stuff.
  3. Dark Mode – Permute now works 100% with the dark mode, even adjusting its Dock icon based on your macOS theme. Image Stitching – Stitch images together into a PDF. HEVC (H.265) Hardware Acceleration – HEVC (H.265) video encoding now supports hardware acceleration, resulting in conversions more than twice as fast.

Given a collection of numbers, nums, that might contain duplicates, return all possible unique permutations in any order. Example 1: Input: nums = 1,1,2 Output: 1.

Question or problem about Python programming:

I know about itertools, but it seems it can only generate permutations without repetitions.

For example, I’d like to generate all possible dice rolls for 2 dice. So I need all permutations of size 2 of [1, 2, 3, 4, 5, 6] including repetitions: (1, 1), (1, 2), (2, 1)… etc

If possible I don’t want to implement this from scratch

How to solve the problem:

Solution 1:

You are looking for the Cartesian Product.


In mathematics, a Cartesian product (or product set) is the direct product of two sets.

In your case, this would be {1, 2, 3, 4, 5, 6} x {1, 2, 3, 4, 5, 6}.
itertools can help you there:

To get a random dice roll (in a totally inefficient way):

Solution 2:

You’re not looking for permutations – you want the Cartesian Product. For this use product from itertools:

Solution 3:

In python 2.7 and 3.1 there is a itertools.combinations_with_replacement function:

Solution 4:

In this case, a list comprehension is not particularly needed.

4 Permute 2

Unobviously, Cartesian product can generate subsets of permutations. However, it follows that:

  • with replacement: produce all permutations nr via product
  • without replacement: filter from the latter

Permutations with replacement, nr

Permutations without replacement, n!

Consequently, all combinatoric functions could be implemented from product:

Permute 2.2 For Macos
  • combinations_with_replacement implemented from product
  • combinations implemented from permutations, which can be implemented with product (see above)

Solution 5:

I think I found a solution using only lambdas, map and reduce.

Essentially I’m mapping a first lambda function that given a row, iterates the columnns

then this is used as the output of a new lambda function

which is mapped across all the possible rows

and then we reduce all the resulting lists into one.

Permute 3

even better

Can also use two different numbers.

Solution 6:

Permute App

First, you’ll want to turn the generator returned by itertools.permutations(list) into a list first. Then secondly, you can use set() to remove duplicates
Something like below:

Hope this helps!
