A benchmark of two approaches to constructing an array. Bytearray vs array+join. Limitation: one should know the length of the array. Within pypy-1.9 the bytearray approach is one order of magnitude faster. In CPython-2.7, bytearray aprox. 35% faster.
import timeit
DATA = 'abcdef'
def bytearr():
bytesn = 1024 * 1024 * 5
s = bytearray(bytesn)
i = 0
while i < bytesn:
s[i] = DATA[i%len(DATA)]
