如何防止python打印二进制符号

Question

I need to print the comments of files inside a zip file :

import zipfile
def info_zip(archive_name):
   with zipfile.ZipFile(archive_name) as challenge:
       for info in challenge.infolist():
            print(info.comment)

but the results i am get aren't pretty:

b'G'
b' '
b'E'
b' '
b' '
b'*'
b'*'
b' '
b'E'

1. How to get rid from those b at the start of every comment?
2. Why are they like that, i know what they are mean buy isn't the comment's content is by the author of the zip file, why he would like to store them as binary ?

Python 3.x

Answer 1

The b indicates that it is a bytes -object that is printed. To get from bytes to string you have to decode the bytes object ( Encode is transform a string to a bytes object).

In order to decode a bytes object you'' have to know the used character encoding .

My guess is that the zip-file header is simply ASCII encoded. You should thus be able to get the wanted result by calling:

myBytesObject.decode('ASCII')
