Please Help! need help creating a matrix!

[victory2006]

i need help to make a board such as this:

-----------Col 0--Col 1--Col 2
Row 0------1------1--------0
Row 1------0------0--------1
Row 2------1------1--------1

(Please ignore the dashes, they were uses to space things out)

where the user enters a number between 3 to 6
and this number will be distinguished as variable 'dim'

The board will be a square matrix of size dim x dim. The contents of
each cell in that matrix will be a 0 or a 1. The computer will populate the matrix with 0’s and 1’s
randomly.

how do u do this??

Please use [CODE] tags to preserve whitespace and indention.

Have you attempted to code this yourself? If you would show some effort, others would be more willing to help.
Hints:
random.choice(0 ,1)
Create a list of lists using a nested for loop or list comprehension

Example:
>>> for i in range(3):
... for j in range (3):
... print i,j
...
0 0
0 1
0 2
1 0
1 1
1 2
2 0
2 1
2 2
>>>

random.choice(0 ,1)

Better make that
random.choice(( 0, 1))

well its something liek this, i started it...

def createboard(dim):
    import random
    global x
    global board
    row = []
    for i in range(dim)
        row.append(random.randint(0,1)
            
    board = []
    for n in range(dim)

Please enclose your posted code in [CODE] [/CODE] tags (See How to Ask a Question). Code tags preserve indention and uses a monospaced font.

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use [CODE] [/CODE] tags in future.

You'll need a for loop inside a for loop. The pseudocode should be more like:

For each row:
    Create a new row.
    For each element in that row:
        Add an element to the row.
    Add the row to the matrix.

Hope this helps.
