That’s where the finally block comes in. Checking for multiple exceptions would ensure your program could continue running even if there was an error opening the file you reference. We could add more errors, such as a ZeroDivisionError or an OSError, depending on the code we are testing.įor instance, you may check for an IOError and a FileNotFoundError if you want to open a file. In this case, our code returns ourVariable is not defined because our code returns a NameError. ![]() There are many types of exception, but some of the most common you will encounter include: ArithmeticError, ImportError, ZeroDivisionError, NameError, and TypeError.
