Try and Except<\/h2>\n\n\n\n

In Python, errors and exceptions can disrupt the flow of your program. To handle these issues gracefully, Python provides try<\/code> and except<\/code> blocks, which allow you to catch and manage exceptions without crashing your program.<\/p>\n\n\n\n

Syntax<\/strong><\/p>\n\n\n\n

try:\n    # Code that may raise an exception\nexcept SomeException:\n    # Code to handle the exception<\/pre><\/div>\n\n\n\n
Example<\/b><\/p>\n\n\n\n
try:\n    result = 10 \/ 0\nexcept ZeroDivisionError:\n    print("You can't divide by zero!")<\/pre><\/div>\n\n\n\n
    \n
  • The code inside the try<\/code> block is executed first.<\/li>\n\n\n\n
  • If an exception occurs, the code inside the except block<\/code> is executed, handling the error.<\/li>\n<\/ul>\n\n\n\n
    Finally<\/h2>\n\n\n\n
    The finally<\/code> block is used to define cleanup actions that should be executed under all circumstances, whether an exception occurred or not.<\/p>\n\n\n\n
    Syntax<\/strong><\/p>\n\n\n\n
    try:\n    # Code that may raise an exception\nexcept SomeException:\n    # Code to handle the exception\nfinally:\n    # Code that will always execute<\/pre><\/div>\n\n\n\n
    Example<\/b><\/p>\n\n\n\n
    try:\n    file = open("example.txt", "r")\nexcept FileNotFoundError:\n    print("File not found!")\nfinally:\n    print("Execution complete.")<\/pre><\/div>\n\n\n\n
      \n
    • The finally<\/code> block runs regardless of whether an exception was raised or not, making it useful for resource cleanup like closing files.<\/li>\n<\/ul>\n\n\n\n
      Raising Exceptions<\/h2>\n\n\n\n
      You can raise exceptions in your code using the raise<\/code> keyword. This is useful when you want to trigger an exception manually.<\/p>\n\n\n\n
      Syntax<\/strong><\/p>\n\n\n\n
      if condition:\n    raise SomeException("Error message")<\/pre><\/div>\n\n\n\n
      Example<\/b><\/p>\n\n\n\n
      age = -1\nif age < 0:\n    raise ValueError("Age cannot be negative!")<\/pre><\/div>\n\n\n\n
        \n
      • The raise<\/code> statement is used to throw a specified exception with an optional error message.<\/li>\n<\/ul>\n\n\n\n
        Handling Multiple Exceptions<\/h2>\n\n\n\n
        You can handle multiple exceptions by specifying them as a tuple in the except<\/code> block or by chaining multiple except<\/code> blocks.<\/p>\n\n\n\n
        Syntax<\/strong><\/p>\n\n\n\n
        try:\n    # Code that may raise exceptions\nexcept (ExceptionType1, ExceptionType2):\n    # Code to handle the exceptions<\/pre><\/div>\n\n\n\n
        Example<\/strong><\/p>\n\n\n\n
        try:\n    result = 10 \/ 0\nexcept (ZeroDivisionError, TypeError):\n    print("An error occurred!")<\/pre><\/div>\n\n\n\n
          \n
        • You can catch multiple types of exceptions using a single except<\/code> block or handle each exception type in separate blocks.<\/li>\n<\/ul>\n\n\n\n
