Write code that sets the value of a variable called name depending on the numeric value in the variable id. If id is 1, set name to 'Alice', if id is 2, set name to 'Bob', if id is 3, set name to 'Carol', and if id is 4, set name to 'David'. If the id is anything else, set name to 'Unknown'. Assume that the variable id has already been initialized (code in python).
