array concatenation

[ashtonn@gmail.com]

Hello,
I have 2 arrays defined with different typecodes.

a = array('B', '\0', 6)
b = array('L', '\0', 526)

for i in range( 6):
    a[i] = 0xFF

for i in range( 520):
    b[i] = 0xCCCCCCCC

How do i concatenate these two arrays so that, i get
b =
0xff 0xff 0xff 0xff 0xff 0xff 0xCCCCCCCC 0xCCCCCCCC
...................................................
...................................................
0xCCCCCCCC

I need an array because i am using a buffer_info method.
