Try, Except, and Finally.py

# Try, Except, and Finally

# Python will output different types of error notifications. These include:
#     - TypeError
#     - NameError
#     - AttributeError
#     - IndentationError
#     - SyntaxError
# Python allows us to manage the output error instead of relying on python itself.
# This is where Try, Except, and Finally comes in.
# These clauses can prevent errors from being fatal to our code.
