wif转私钥

def wif_to_priv(wif):

    import binascii

    _base58 = base58.b58decode(wif).encode('hex')

    # print(_base58)

    remove_last4 = _base58[:-8]

    # print(remove_last4)

    remove_first2 = remove_last4[2:]

    _int = int(remove_first2, 16)

    _bin = bin(_int)

    print _bin

    print(remove_first2 + "|" + _bin[2:].zfill(256))

    #print(remove_first2 )

    return remove_first2, _bin[2:].zfill(256)

输出结果如下: 

0b111101010001000011011111000001011111111101011101000001111101011011011010111110111100100101000000110100010011011010100111111110010110111100001011011010100111011011001110001000011101010101011011101010110011111001010010110100110111011110101100110110000011110

输出定长(如：输出256位，不足的部分补0),使用zfill：

 _bin[2:].zfill(256)

如果是压缩私钥的话，得到的结果后面为：私钥对应的大数+01
