Python script to perform multiple commands sequentially over SSH in a single connection

Known issue:
Execution of commands goes on one after another, even though one/many intermediate commands fails
(NOT recommended, if your commands and dependant on previous commands execution)
  
Kindly share your thoughts on this script.
