将字节数组转换为 int python 错误结果

Question

I know this should be easy, but I just can't get the syntax right for python.

My int is not converted correctly. This is the output of my 2 print statements. My output should be 9718 instead of 959918392 .

bytearray(b'9718')
959918392

This is my conversion. I don't understand what am I doing wrong.

print(size)
print(int.from_bytes(size, byteorder='big'))

Answer 1

What you tried assumes the number is directly encoded as bytes. You actually want to parse it from ascii, which you can do like this:

int(b'9718'.decode('ascii'))
