Answer 1

How can I create a folder to add files and zip the folder?
You can do what you want by following these steps:
To create a folder, use os.mkdir like this:
import os
os.mkdir('spam') # your folder name
then you can write files to it or use shutil.copy to make copies of existent files.
# to write files:
with open('./spam/eggs.txt', 'w') as fp: # creates a text file in spam named eggs.txt
fp.write('hello') # write hello
# to copy files
import shutil
shutil.copy('eggs.txt', './spam/eggs.txt') # copy eggs.txt from the current working dir to spam folder
then to zip the folder, you had the right idea, to use zipfile like this:
from zipfile import ZipFile, ZIP_DEFLATED
zipfp = ZipFile('spam.zip', 'w', ZIP_DEFLATED) # create a new zip file named spam.zip
for root, dirname, files in os.walk('./spam'): # walk in the spam folder
[zipfp.write(os.path.join('./spam',file)) for file in files] # write them to the zip file
zipfp.close()
A complete example:
import os
from zipfile import ZipFile, ZIP_DEFLATED
os.mkdir('spam')
with open('./spam/eggs.txt', 'w') as fp:
fp.write('hello')
with ZipFile('spam.zip', 'w', ZIP_DEFLATED) as zipfp:
for root, dirname, files in os.walk('./spam'):
[zipfp.write(os.path.join('./spam',file)) for file in files]
The result of this code is it produces a compressed folder named spam.zip and in the zip file, there's a txt file named eggs.txt which contains the text 'hello'.
To clarify for the OP:
[zipfp.write(os.path.join('./spam',file)) for file in files]
is equivalent to:
for file in files:
zipfp.write(os.path.join('./spam',file))
it's just simpler to write it using list comprehension.
