Introduction
Set basics
Relationships between sets
Instruction
Very well done! Instead of discard(), you can use remove() to delete information. The difference is that remove() throws a KeyError when a given element is not present in the list. Take a look:
newcomers = {'Kathleen Lopez', 'Clinton Keller', 'Katie Gutierrez', 'Pablo Fleming'}
try:
newcomers.remove('Strange Name')
print('Removed successfully!')
except KeyError:
print('Employee not found!')
In the code above, we tried to remove a person called 'Strange Name' from the set. Such a person does not exist in the set, so we'll get a KeyError. We handle this error by printing 'Employee not found!'.
Exercise
As terrible as it may sound, we need a way of firing people from the new branch. Add some new code to the template that will do the following:
Ask the user to provide an employee
{x}:Which employee would you like to fire?
If
{x}exists in the set, remove it and print:{x} was fired.Otherwise, print:
The person named {x} does not work for us!
