You can use the following ways to fill in a default value instead of getting an error message for missing key. you can test for keys ahead of time in if statements, use a try statement to catch and recover from the exception explicitly, or use the dictionary get method shown earlier...
In this case, we do not check what the value of the missing key is but rather we check whether the key is in the dictionary or not. This is a special way of handling an exception which is used rarely. This technique of handling exceptions is known as Look Before You Leap(LBYL). Usi...
