Errors that occur during the runtime of a Python program. These exceptions are predefined in Python and handled automatically by the interpreter.

Exceptions that are defined by the programmer to handle specific situations within the program.

An exception raised when the value provided is incorrect or inappropriate for the expected data type.

This exception occurs when the user interrupts the program execution, usually by pressing keyboard keys like Ctrl+C or Ctrl+Z.

This exception is raised when a module that is required by the program cannot be found.

A bug or an unexpected event that can occur during the execution of a program. This can disrupt normal program flow and may lead to unexpected behavior, errors, and crashes.

Errors that occur during the compilation or parsing of a program. These errors generally relate to syntax or grammar rules of the programming language, hindering the program from being understood by the compiler or interpreter.

Errors that happen during the runtime of a program. They occur while the program is running, often caused by user input, unexpected data, or hardware failures. These errors can't be detected during compilation.

Code used to handle exceptions, allowing the program to gracefully manage unexpected situations and continue executing rather than crashing abruptly. This helps make programs more robust and reliable.

Types of Exceptions:

(1) ZeroDivisionError: Occurs when trying to divide by zero (mathematically impossible).

(2) FileNotFoundError: Happens when the program attempts to access a file that doesn't exist.

(3) ValueError: Raised when a function receives an argument of the correct data type but with an inappropriate value.

(4) TypeError: Happens when an operation is attempted on an object of the wrong type.

A code block executed when a specific exception is caught. It allows you to handle the error gracefully and continue program execution.

A code block executed only if no exception occurs in the preceding try block. It allows you to perform actions that are specific to the successful execution of the try block.

A code block that occurs regardless of whether an exception was raised or handled. It ensures that certain cleanup operations, such as closing files or releasing resources, are executed.

A statement used to manually raise an exception, allowing you to control the flow of execution and handle specific error scenarios.

The process of using mechanisms like 'try', 'except' and 'else' blocks to control the flow of a program when an exception occurs. It allows the program to gracefully deal with unexpected situations without crashing.

Exception handling is a mechanism in programming that allows you to gracefully handle errors and unexpected events that occur during program execution, preventing the program from crashing and ensuring a smooth workflow.

Exception handling is crucial for building robust and reliable programs. It allows you to gracefully address errors, preventing program crashes and ensuring a smooth workflow.

An exception is an event that occurs during program execution that disrupts the normal flow of instructions. Examples include dividing by zero, accessing a non-existent file, or encountering a network error. These events can cause a program to crash if not handled correctly.

The try...except block is a fundamental construct in exception handling. It allows you to define a block of code (the 'try' block) where potential exceptions might occur. If an exception is raised within this block, the program execution jumps to the corresponding 'except' block, where you can handle the error.

The try...except block is essential for handling exceptions. It allows you to isolate the code where exceptions might occur ('try' block) and provide alternative actions ('except' block) in case of an error. This helps maintain program stability and avoid abrupt terminations.

A catch block is a specific section within the try...except block that handles a particular type of exception. You can have multiple catch blocks for different exceptions, enabling you to handle errors with precision and tailor your responses.

When an exception occurs, the program usually terminates abruptly. However, using exception handling, you can gracefully handle these errors, prevent program termination, and continue execution.

By using exception handling, you can create more robust and reliable programs. It allows you to gracefully handle errors and unexpected events, preventing program crashes and ensuring a smooth workflow.

A statement in Python used to test a condition and raise an exception if the condition is not met. It helps in detecting and handling potential errors during program execution.

When a conditional evaluation within an 'assert' statement results in False, an AssertionError exception is raised, interrupting the normal flow of program execution.

The 'try' block encloses code that might raise exceptions. It's like a safe zone for potentially risky operations.

The 'except' block deals with raised exceptions. They act like 'catchers' for specific types of errors triggered within the 'try' block.

Code within the 'else' block runs if no exception is raised within the 'try' block. Think of it as the 'all clear' stage.

The 'finally' block ensures that its enclosed code always executes, regardless of whether an exception occurs or not. It's like a cleanup crew.

You can create custom exceptions by defining new exception classes inheriting from the 'Exception' class. Think of it as having a personalized error message.

A 'ZeroDivisionError' is raised when attempting to divide by zero. Think of it as a math crime you can't commit!
