In Python, programs are executed sequentially; the Python interpreter reads a program one line at a time, from left to right and top to bottom, just as you read this page. The interpreter executes operations and functions in the order that they appear. This is known as control flow. <\/strong><\/p>

<\/p>

Without control flow expressions, a program is simply a collection of statements that are executed sequentially. Control flow allows you to execute specific code blocks conditionally and\/or repeatedly, and these fundamental building blocks can be combined to create complex code.<\/p>

In our previous blog, we explored the building blocks of Python programs: variables and data types<\/a>. Now, we’re venturing into the realm of control flow, a fundamental concept that empowers your programs to make decisions, repeat actions, and structure their logic effectively. Just like variables and data types provide the foundation for storing and manipulating information, control flow mechanisms dictate how your program executes, transforming it from a static collection of instructions into a dynamic and interactive entity.<\/p>

This blog post will serve as your comprehensive guide to control flow in Python, equipping you with the tools to craft powerful and versatile programs. So, buckle up and get ready to unlock the true potential of your Python code!<\/p>

Conditional Statements<\/h1>

Conditional statements enable your code to make decisions based on specific conditions. The main conditional statements in Python are if<\/code>, elif<\/code>, and else<\/code>.<\/p>

If Statements:<\/h2>

The if statement is one of the most common control flow statement types. It checks a condition and then performs one of two functions:<\/p>

Let’s say we want to know whether the input value of an is positive or negative. We use the if statement to specify two conditions: if an is greater than 0, print ‘Its positive’; if an is less than 0, print ‘Its negative.’<\/p>
