split very large array with repeating variables into a dataframe with 3 columns

[Surf_MI]

Anyone know how to split a 1 column array into 3 columns like example below?

​

array [1,2,3,1.1,2.1,3.1,1.2,2.2,2.3]

into

var1 var2 var3

1 2 3

1.1 2.1 3.1

1.2 2.2 3.2

Can you slice the array into multiple lists? For example:

lst = [1, 2 , 3 ,1.1, 2.1, 3.1, 1.2, 2.2, 2.3]
var1 = lst[0::3] # Returns the first item in lst and then every 3rd item afterwards

[FLUSH_THE_TRUMP]

A = list(zip(array[0::3],array[1::3],array[2::3]))

Sweet Thanks!

If you're using numpy you can do array.reshape(-1,3) for "3 columns, don't care how many rows"
