A group of statements that perform a specific task within a program.

A program where each task is in its own function.

Executes code then ends, doesn't return a value.

Executes code and returns a value to the calling statement.

Simpler code, code reuse, better testing, faster development, easier teamwork.

The main function is the starting point of a program and determines the program's overall logic by calling other necessary functions.

Indentation is crucial in Python as it defines code blocks. Each line within a block must start with the same number of spaces or tabs. Using both can cause errors.

A flowchart is a graphical representation of the steps within a function, showing the flow of logic using symbols like rectangles and arrows.

A hierarchy chart visualizes the relationship between different functions within a program, showing which functions call other functions.

A local variable is a variable created and defined within a specific function. It can only be accessed within that function.

Yes, functions can be empty. The pass keyword creates an empty function that does nothing but serves as a placeholder for future development.

The input() function pauses the program execution and waits for the user to enter text using the keyboard. Once the user presses enter, the entered text is returned as a string.

Using separate flowcharts for each function within a program enhances clarity and understanding by focusing on the individual logic and steps of each function.

A variable that is created and can only be accessed within the function it is defined. It is not accessible from outside its containing function.

The region of a program where a variable can be accessed and used. For local variables, their scope is limited to the function where they're defined.

A piece of data that is passed into a function when it is called. It provides input for the function to work with.

A variable that receives the argument sent to a function when it is called. It acts as a placeholder for the argument's value.

A parameter acts as a placeholder inside a function that accepts an argument's value when the function is called. It helps the function perform its operation with specific input.

Arguments are passed to a function when the function is called. They are placed in parentheses following the function name.

A parameter's scope is limited to the function in which it is used. It is accessible only within that function.

Functions can accept multiple arguments by defining a list of parameters separated by commas. Arguments are passed positionally, matching to corresponding parameters.

A special value in Python signifying the absence of a value. It indicates that a function did not return anything meaningful.

It's used in functions to signal that an error occurred or there's no valid result to return.

A Python library containing pre-built tools for mathematical calculations like trigonometry, logarithms, and more.

The line 'import math' allows you to use functions from the math module in your code.

A unit of angular measurement used in the math module functions, different from degrees.

Global variables can be accessed by any statement within the program file, including within functions.

To modify a global variable inside a function, you need to explicitly declare it using the 'global' keyword.

A global name that references a value that cannot be changed.

Python doesn't have a true global constant, so we simulate it by declaring a global variable and never reassigning it within functions.

A group of statements that perform a specific task, but doesn't return a value.

A group of statements that perform a specific task and returns a value to the part of the program that called it.

A library of pre-written functions that comes with Python, offering common programming tasks.

Files that store functions of the standard library, helping organize those not built into the interpreter.

To use a function stored in a module, you need to write an import statement at the top of your program.

The ability to create random numbers, useful for various programming tasks.

A Python module that includes functions for working with random numbers.

Calling a function from a module using the format: module_name.function_name()

Initializes the formula that generates random numbers, causing different seeds to produce different random number series.

To write a value-returning function, include a 'return expression' statement that sends back a value.

A technique used to prevent the main function from being executed when the file is imported as a module by using the if __name__ == '__main__': condition.

This conditional statement is used to execute a specific block of code only when the script is run directly, not when it's imported as a module.

It helps to separate the code that runs when the file is executed directly from the code that provides functions to be used by other modules.

When a file is run, its entire code is executed. When a file is imported, only its functions and attributes are loaded for use in the main script.

When a script is run directly, __name__ is set to '__main__'. When it's imported, __name__ is set to the module's name.
