The base example is to use a try/except block. You can raise exceptions in code that can be caught by the except block.
try: linux_interaction() except: print('Linux function was not executed')
class LinkedList: def __init__(self, head=None): self.head = head def getFirst(self): if self.head == None: raise Exception("No items in list") else: return self.head try: ll = LinkedList() ll.getFirst() except Exception, error: print(error)
