[英]Python: Converting from binary to String
In Python, I have been able to take in a string of 32 bits, and convert this into a binary number with the following code: 在Python中,我已经能够接收一个32位的字符串,并使用以下代码将其转换为二进制数:
def doConvert(string):
binary = 0
for letter in string:
binary <<= 8
binary += ord(letter)
return binary
So for the string, 'abcd'
, this method will return the correct value of 1633837924, however I cannot figure out how to do the opposite; 所以对于字符串'abcd'
,这个方法将返回正确的值1633837924,但是我无法弄清楚如何做相反的事情; take in a 32 bit binary number and convert this to a string. 获取32位二进制数并将其转换为字符串。
If someone could help, I would appreciate the help! 如果有人可以提供帮助,我将非常感谢您的帮助!
If you are always dealing with a 32 bit integer you can use the struct
module to do this: 如果您始终处理32位整数,则可以使用struct
模块执行此操作:
>>> import struct
>>> struct.pack(">I", 1633837924)
'abcd'
Just make sure that you are using the same endianness to both pack and unpack otherwise you will get results that are in the wrong order, for example: 只需确保使用相同的字节顺序来打包和解包,否则您将获得错误顺序的结果,例如:
>>> struct.pack("<I", 1633837924)
'dcba'
