(To note, the "Mount Drive" within Colab's file browser UI mounts in the "/contents" directory.

!cp "/content/drive/My Drive/MyFile.zip" "/content/MyFile.zip"

-------To Unzip an imported Zip file-------->

!unzip MyFile.zip -d My_Output

------To Zip a folder for download -------->
(E.g. a cache folder. There maybe easier ways)

!pip install -U -q PyDrive

from google.colab import files
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials
import zipfile
import os
import sys

zipname = 'ZippedFile'

def zipfolder(foldername, target_dir):
zipobj = zipfile.ZipFile(foldername + '.zip', 'w', zipfile.ZIP_DEFLATED)
rootlen = len(target_dir) + 1
for base, dirs, files in os.walk(target_dir):
for file in files:
fn = os.path.join(base, file)
zipobj.write(fn, fn[rootlen:])

zipfolder(zipname, '/content/ToZip')

while(1):
a.append('1')

---------------To Hide Cell Output--------->

document.querySelector("colab-toolbar-button#connect").click()
}
setInterval(ClickConnect,60000)
