So, this works perfectly fine and fast. But it scares me that it's
deprecated and Python 4 will not support it anymore.
Hm, this doesn't even work with Python 3:
My mistake. I should have tested better.
data = array.array("u", u"x"*1000)
data[100] = "y"
re.search("y", data)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.4/re.py", line 166, in search
return _compile(pattern, flags).search(string)
TypeError: can't use a string pattern on a bytes-like object
You can search for bytes
re.search(b"y", data)
<_sre.SRE_Match object; span=(400, 401), match=b'y'>
data[101] = "z"
re.search(b"y", data)
<_sre.SRE_Match object; span=(400, 401), match=b'y'>
re.search(b"yz", data)
re.search(b"y\0\0\0z", data)
<_sre.SRE_Match object; span=(400, 405), match=b'y\x00\x00\x00z'>
but if that is good enough you can use a bytearray in the first place.
Maybe I'll try that. Thanks for the suggestions!
