以下文字在 python 中的含义是什么？

Question

The literal values expressed in python as

'b"8.23"' and 'b"1.25"'

These are expressions specific to python.

Answer 1

The b character before a string produces a variable of byte type instead of string type. You may read about this definition on the official website .

Answer 2

The character 'b' shows that the given variable is of type byte, not string.

Let me distinguish between string and byte definitions to make it clear,

str = '...' 
# Above literals is sequence of Unicode characters (Latin-1, UCS-2 or UCS-4)
bytes = b'...' 
# Above literals are sequence of octets (integers between 0 and 255)
