    Study Notes

    Exception Handling in Python

    • Errors in programming are issues or defects that cause abnormal behavior or unexpected output
    • These are also referred to as bugs or faults
    • Errors are categorized as syntax errors and runtime errors

    Syntax Errors

    • These errors occur during the programming process due to violating the rules of the programming language
    • They are also known as parsing errors
    • Example: A missing or incorrect symbol in code

    Runtime Errors

    • These errors happen during program execution
    • They can be due to incorrect user input, memory issues, or logic errors
    • They are also called exceptions
      • Examples include division by zero, file not found, type errors, value errors

    What is an Exception?

    • Exceptions are unwanted or unexpected events that disrupt the normal flow of a program
    • Examples include division by zero, file not found, type errors, value errors

    Types of Exceptions

    • Built-in Exceptions: These are predefined exceptions in Python
      • SyntaxError
      • ValueError
      • IOError
      • KeyboardInterrupt
      • ImportError
      • EOFError
      • ZeroDivisionError
      • IndexError
      • NameError
      • TypeError
      • OverflowError
    • User-defined Exceptions: Programmers can create custom exceptions
      • These exceptions are tailored to specific program needs

    Exception Handling with try, except, and finally

    • try: The block where the code that may generate an exception is placed
    • except: Handles specific types of exceptions
    • else: Executes if no exceptions occur in the try block
    • finally: Executes regardless of whether an exception occurred or not

    Raising Exceptions

    • Using the raise statement, developers can explicitly create exceptions
      • Typically used for custom, user-defined exceptions

    Multiple Except Clauses

    • You can have multiple except blocks to handle different types of exceptions

    Assert Statement

    • It's a debugging tool
    • Used to test conditions inside your code
    • If the assertion fails, an AssertionError is raised

    Catching Exceptions

    • A mechanism used to deal with exceptions if they occur within a program
      • Keeps the program running smoothly despite errors
