I tried to translate the following Python code to Go
import random list = [i for i in range(1, 25)] random.shuffle(list) print(list) but found my Go version lengthy and awkward because there is no shuffle function and I had to implement interfaces and convert types.
What would be an idiomatic Go version of my code?

math/rand package of go provides a Shuffle method that can be used shuffle an array or a slice. This method pseudo-randomizes the order of elements using the default source. pseudo-randomizes means that for a fixed input seed it will generate the same randomization.
Shuffle an Array in Python Using the random.shuffle() method takes a sequence as input and shuffles it. The important thing to note here is that the random. shuffle() does not return a new sequence as output but instead shuffles the original sequence.
Python Random shuffle() Method The shuffle() method takes a sequence, like a list, and reorganize the order of the items. Note: This method changes the original list, it does not return a new list.
dystroy's answer is perfectly reasonable, but it's also possible to shuffle without allocating any additional slices.
for i := range slice { j := rand.Intn(i + 1) slice[i], slice[j] = slice[j], slice[i] } See this Wikipedia article for more details on the algorithm. rand.Perm actually uses this algorithm internally as well.
