1. This is example script so I don't care about code quality and your opinion about it.
2. This script should be launched from command line.
3. You need Periscope application consumer keys to use this script. 
4. You can't create your own Twitter application and use its keys to access Periscope.
5. Don't ask me for consumer keys!
6. If you see errors then your keys are wrong.
