Document Summary
References: code seen in the pictures can be found on the csc148 website: http://www. teach. cs. toronto. edu/~csc148h/winter/index. shtml. Stacks and sacks can have different implementations: use python lists vs. dictionaries, so it doesn"t make sense to have implementation in a super class. Consider this code that has a lot of errors: If we run it, python never prints the message we got through because of the first zero. If there is any exception evoked, the except block notices it, prints a message, and continues to run through the code. When this code is run, we get to the message we got through it! . It prints the message ooooops! , the type of error, and the message at the end of the code that it didn"t print originally. Exception is too broad -> looks for every single possible exception: add clause -> tells you what kind of exception to look for. Notice how only the first error is displayed -> only notices first error.
