不知道出什么问题了，尝试生成5x5网格python 1-25

Question

I am not sure what I am doing wrong, if anyone can see exactly, please inform me.

Tried:

grid = [[n in range(1,6)*5]]

and

grid [[]*5 for n in range(1,25)]

My code:

grid = [[x for x in range(1,25)] for y in range(5)]

Output:

[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24], [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24], [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24], [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24], [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24]]

Desired:

[[1,2,3,4,5], [6,7,8,9,10], [11,12,13,14,15],[16,17,18,19,20],[21,22,23,24,25]]

Answer 1

It's fairly obvious that values in inner lists have to be related both to internal counter in each list (x) and position of list in outer list (y). Your code fails to take care about second requirement.

grid = [[1+x+5*y for x in range(5)] for y in range(5)]

Answer 2

You are iterating in a range from 1 to 24(inclusive) in your inner loop, which is why your lists are too long, and have the same values in them.

You somehow need to make the variable of your outer loop dictate the inner loop so each range within the inner loop start from a different point. Also, calibrating the length of the inner range is essential.

That being said, I suggest the following to get your desired output.

grid = [list(range(i, i+5)) for i in range(1, 26, 5)]

Answer 3

You can cut a list into sublist of 5, see this code

data=range(1,26)
len_sublist = 5
print [data[x:x+len_sublist] for x in xrange(0, len(data), len_sublist)]
