How to create a table without using methods or for-loops?

I'm trying to create a 4x3 table without methods or for-loops. I'd like to use what I learned in class, which is booleans, if-statements, and while-loops.

I want it so that if I input create_table('abcdefghijkl') it would start from the the left top most row and column and go down until the end of the column and then start again at the top of the next column and so on, like displayed below:

| a | e | i |

| b | f | j |

| c | g | k |

| d | h | l |

Below is what I have so far. It's not complete. How do I add to the function so that after 4 rows down, the string should continue to the next column starting from the top? I'm wracking my brain over this.

All examples I can find online uses for loops and methods to create tables such as these, but I'd like to implement the while loop for this one.

Thanks in advance!

def create_table(table):
    t =  "" + "|" + ""
    i = 0
    while i < 12:
        t = t + " " + "|" + table[i] + " "
        i=i+1
        print(t)
    return table

You can translate most for loops to while loops with a simple recipe, so if you figure out how to do it with a for loop, then you are good to go. If you have

for x in s:
    {statements}

Make it

i = 0
while i < len(s):
    x = s[i]
    {statements}
    i += 1

It just won't work for some enumerable types that don't support length and indexing, such as generators.

Think about it in terms of rows instead of columns. You're writing out a row at a time, not a column at a time, so look at the indices of the individual cells in the original list:

| 0 | 4 | 8 |

| 1 | 5 | 9 |

| 2 | 6 | 10 |

| 3 | 7 | 11 |

Notice each row's cells' indices differ by 4. Find a simple expression for the nth row's cells and the task will become much easier, as you'll essentially be printing out a regular table.

Because you are printing to the terminal, you would want to think about printing each horizontal row, rather than each vertical column. Try something like:

table = 'abcdefghijkl'
i = 0
while i < 4:
    print("| {} | {} | {} |".format(table[i], table[i+4], table[i+8]))
    i += 1
