>>> struct.pack("b"*len(x), *x)
'\x01\x02\x03\x04\x05'

but if you're working with arrays, it probably makes
more sense to use the built-in array module:

>>> import array
>>> array.array("B", x).tostring()
'\x01\x02\x03\x04\x05'

or you could use map/join:

>>> import string
>>> string.join(map(chr, x), "")
