如何读取python结构的结果？

Question

Can somebody please tell me how do I read the result b'\\x9a\\x99\\x99?' of

import struct
data = struct.pack("@f", 1.2)
print(data)

What does \\x9a represent? Or \\x99 ? How do I translate this back to 1.2 ?

Answer 1

The data is stored in a binary format. To get the value back, use struct.unpack :

import struct
data = struct.pack("@f",1.2)
print(struct.unpack("@f",data))
