Python LookupError Exception
Example
Catch both an IndexError and a KeyError with LookupError:
fruits = ["apple", "banana"]
car = {"brand": "Ford"}
try:
print(fruits[5])
except LookupError:
print("The list item does not exist")
try:
print(car["color"])
except LookupError:
print("The dictionary key does not exist")

Definition and Usage
The LookupError exception is the base class for the errors that occur when a key or an index is not found.
IndexError (for lists, tuples and strings) and KeyError (for dictionaries) both inherit from LookupError, so except LookupError catches both of them.
