如何在Python中将字符串字节转换为字节

Question

I need something like that:

st = "1001000"
bt = toByte(st)
print(bt) # b'H'

Thanks for your help.

Answer 1

You are looking for:

def tochr(bitstr):
    return chr(int(bitstr, 2))

or for a bytestring:

def tobyte(st):
    return bytes([int('1001000',2)])

For example:

>>> tochr('1001000')
'H'
>>> tobyte('1001000')
b'H'
