For example, given a list 1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8
and a number 4, it returns a list of list with length of 4, that is
(1, 2, 3, 4), (5, 6, 7, 8), (1, 2, 3, 4), (5, 6, 7, 8)
.
Basically I want to implement the following Python code in Powershell.
s = 1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8
z = zip(*[iter(s)]*4) # Here N is 4
# z is (1, 2, 3, 4), (5, 6, 7, 8), (1, 2, 3, 4), (5, 6, 7, 8)
The following script returns 17 instead of 5.
$a = 1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,0
$b = 0..($a.Length / 4) | % { @($a[($_*4)..($_*4 + 4 - 1)]) }
$b.Length
PS> $a = 1..16
PS> $z=for($i=0; $i -lt $a.length; $i+=4){ ,($a[$i]..$a[$i+3])}
PS> $z.count
4
PS> $z[0]
1
2
3
4
PS> $z[1]
5
6
7
8
PS> $z[2]
9

12
PS> $z[3]
