The Python I like - A string to integer converter
The following function converts a sequence of bytes into an integer. It is endianness-sensitive:
|
def ordn(big=1): if big % 2: def bordn(seq): if len(seq) > 1: return ord(seq[-1]) + (bordn(seq[:-1]) << 8) else: return ord(seq[0]) return bordn else: def lordn(seq): if len(seq) >1: return ord(seq[0]) + (lordn(seq[1:]) << 8) else: return ord(seq[0]) return lordn |
>>> ordn(1)('\x01\x00')
256
>>> ordn(0)('\x01\x00')
1
Ok, that's probably not the prettiest nor the fastest way to do...
