I am new in python programming and i am a bit confused. I try to get the bytes from a string to hash and encrypt but i got

b'...'

b character in front of string just like the below example. Is any way avoid this?.Can anyone give a solution? Sorry for this silly question

import hashlib

text = "my secret data"

pw_bytes = text.encode('utf-8')

print('print',pw_bytes)

m = hashlib.md5()

m.update(pw_bytes)

OUTPUT:

print b'my secret data'

解決方案

Decoding is redundant

You only had this "error" in the first place, because of a misunderstanding of what's happening.

You get the b because you encoded to utf-8 and now it's a bytes object.

>> type("text".encode("utf-8"))

>>

Fixes:

You can just print the string first

Redundantly decode it after encoding

總結
