var toFind = "eCard number is:";
var startIndex = res.indexOf(toFind) + toFind.length + 1;

var cardNumber = res.slice(startIndex, startIndex + endIndex);

On Android (Its better to use Pydroid 3 instead of Termux)

You can also run this script in android (How to run python script on android ?)

1. Download and install Termux app. (remember to give storage permission from phone's settings and turn off battery optimization for Termux app to make app run long)
2. Run following commads :
   • apt-get update
   • apt-get install python
   • pip install requests
3. Know you can run python script on android
   -savedir or -sd argument is compulsory for android.

For example :

python '/storage/emulated/0/Download/LyndaDownloader.py' -savedir '/storage/emulated/0/Download/'
or
python '/storage/emulated/0/Download/LyndaDownloader.py' -url 'https://www.lynda.com/C-tutorials/C-Essential-Training/772322-2.html' -savedir '/storage/emulated/0/Download/' -q 2 

On Linux

1. Run following commads to install Python:
   • sudo apt-get update
   • sudo apt-get -y install python3
   • sudo apt-get -y install python3-pip
   • sudo pip3 install requests or pip install requests
2. Know you can run python script on Linux

For example :

python3 '/home/navpreetdevpuri/Downloads/LyndaDownloader.py'

Optional arguments with python script

If you run script without this arguments then It will ask this things on run time

1. -url : Url link of Lynda course.
2. -savedir or -sd : Directory location (Full path) on your system where you want to save files (by default set to the same location as LyndaDownloader.py).
3. -quality or -q : Video quality (360p or 0, 540p or 1, 720p or 2).
