Read zip file in python3 same like python2

Question

I save below code in 1 file. lets say read_zipfile.py.

with open("demo.zip", "rb") as f:
 read_data = f.read()
 print (read_data) 

python2 giving below output:

[harsha@os]$ python2 read_zipfile.py
PK�flNdemo/PK
�flN����demo/hello.txtThi is Hello file
PK
�KK
 demo/hi.txtPK?�flN$��Ademo/
 �m@Q���^;T����m@Q���PK?
�flN����$ ���#demo/hello.txt
 �m@Q����m@Q����m@Q���PK?
�KK
 $ ���ademo/hi.txt
 ���B�������,���PK�

---

python3 giving below output:

[harsha@os]$ python3 read_zipfile.py

How can I get python2 output format using python3?

• Aran-Fey: That is exactly the same data, it's just printed differently. What's your goal here? Why are you printing the binary representation of a zip file?
• Harsha Biyani: @Aran-Fey I want data to be print like python2 in python3
• Harsha Biyani: @Aran-Fey : Can I convert python3 output in python2 format?
• Harsha Biyani: @Aran-Fey Python3 giving me in byte format. I want python2 output using python3.
• martineau: Harsha Biyani: Why are you printing the binary data in a .zip file anyway?

Answer 1

In python3, f.read() returns a bytes, you should choose a encoding such as utf-8 and convert it to str.

Then it will be print like python2.

with open("demo.zip", "rb") as f:
 read_data = f.read()
 #print (read_data) 
 s = read_data.decode('latin1')
 print(s)

• Harsha Biyani: I tried this. This not giving me in the same format like Python2 output
• He Xiao: it depends on , what is the actually decode your console use, it maybe not utf-8
• Harsha Biyani: @martineau : Thanks a lo for your help. latin1 helped me to solve the problem. Could you please add the answer? so that I can accept the same.
• martineau: @Harsha Biyani: That's not necessary. I suggest you accept this one which contains the essence of the answer.
• martineau: @HarshaBiyani: BTW, using the latin1 encoding to store binary data is kind of a "trick" in Python 3. See this answer to a related related question.

Answer 2

In order to dump raw bytes to STDOUT in Python 3, use the binary stream underlying sys.stdout. It's accessible as the .buffer attribute.

Change print(read_data) to

sys.stdout.buffer.write(read_data)
sys.stdout.buffer.write(b'\n')

The last line is necessary if you want to exactly mimic what print does.
