Python string prefix

Normal string

Generic strings are Unicode encoded, and similar to C, can be escaped using \ To escape, such as

a = the test \ n Test " Print (a)

Output

Test Test

Front Plus R

Precede the string with an R to indicate that the string is raw string and does not recognize escape.

b = R "Test\ntest" Print (b)

Output

Test\ nTest

This is useful when using regular expressions.

Front Plus B

Generates a byte sequence object ByteArray. This is useful when you need to send data in a byte sequence, such as a network send

message = b "get/http/1.1 \r\n\r\n " s . Sendall (message)

The type of message is no longer str, but bytes.
