Understanding Python Control Flow and Functions (Section -3)

1. Control Flow Statements

Control flow statements allow you to control the order in which your program executes code. There are several types of control flow statements in Python, including:

• if-else statements: if-else statements allow you to execute different blocks of code depending on whether a condition is true or false.

for loops: for loops allow you to iterate over a sequence of values.

while loops: while loops allow you to execute a block of code while a condition is true.

2. Functions

Functions allow you to organize your code into reusable modules. You can define a function once and use it multiple times throughout your program. Functions can take arguments and return values, and they can be used to perform a wide range of tasks.

In this example, we define a function called add_numbers that takes two arguments and returns their sum. We then call the function with the values 5 and 10 and print the result.

3. Modules

Python modules are files containing Python code that can be imported into your program. Modules can contain functions, variables, and classes that can be used throughout your program. Python has a wide range of built-in modules, as well as third-party modules that you can install and use in your own projects.
