Method # 1: Using a Lambda
This task can be accomplished using a lambda function. In this we check a string for None or an empty string using the or operator and replace the None values with an empty string.

Output:
The original list is: [’Geeks’, None,’ CS’, None, None] The list after conversion of None values: [’Geeks’,’ ’,’ CS’, ’’, ’’]
Method # 2: Using str()
It’s just that the str function can be used to accomplish this particular task, because None also evaluates to False and, hence, it will not be selected, but instead a string converted to false will be returned, which evaluates to an empty string.

The original list is: [’Geeks’, None,’ CS’, None, None] The list after conversion of None va lues: [’Geeks’,’ ’,’ CS’, ’’, ’’]
