With these it helps i have a text file like this , You could do it like this using index slicing and zip:
infile = open('./Desktop/nums.txt')

board = infile.read().strip('\\n').split(',')
# the numbers are in string format at this point
# board ['1', ' 2', ' 3', ' 4', ' 5', ' 6', ' 7', ' 8', ' 9']
board_array = [[int(x),int(y),int(z)] for x,y,z in zip(board[::3], board[1::3], board[2::3])]
>>> board_array
[[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Read text file into array (Storing only numerical data)

Hope that helps To capture everything after the colon you just need to split on it and take the second element of each result:
For Each s In StringArrayOfTextLines
    Console.WriteLine(s.Split(":")(1).Trim())
