如何将二进制数转换为整数而不使其为正数

Question

我需要一个函数,将二进制符号转换为整数.

int("1010",2) 
#this will be converted to 10 instead of -6 - 
# i want a fucnction that will convert it into -6 

Answer 1

您可以使用该bitstring模块:

from bitstring import Bits
nr = Bits(bin='1010')
print(nr.int) # .int here acts as signed integer. If you use .uint it will print 10
