One option for Python 2.6 and later is to use a bytearray:
Python 2.6及更高版本的一个选项是使用bytearray：
>>> b = bytearray('hello')
>>> b[0]
104
>>> b[1]
101
>>> list(b)
[104, 101, 108, 108, 111]
For Python 3.x you'd need a bytes object rather than a string in any case and so could just do this:
对于Python 3.x，在任何情况下都需要一个字节对象而不是字符串，因此可以这样做：
>>> b = b'hello'
>>> list(b)
[104, 101, 108, 108, 111]

Do you mean the ascii values?
你的意思是ascii值吗？
nums = [ord(c) for c in mystring]
or
要么
nums = []
for chr in mystring:
nums.append(ord(chr))
#3
2
Perhaps you mean a string of bytes, for example received over the net, representing a couple of integer values?
也许你的意思是一串字节，例如通过网络接收，代表几个整数值？
In that case you can "unpack" the string into the integer values by using unpack() and specifying "i" for integer as the format string.
在这种情况下，您可以使用unpack（）并将整数指定为“i”作为格式字符串，将字符串“解包”为整数值。
