2. Control Flow: If-Else Statements and Loops

Control flow statements like if-else and loops allow your program to make decisions and repeat actions. These are essential concepts in any programming language, and you’ll use them frequently when writing code.

If-Else Statement Example

An if-else statement checks a condition and executes code based on whether that condition is true or false. Here’s an example in Python where a user inputs their age, and the program checks if they are eligible to vote:

age = int(input("Enter your age: "))

if age >= 18:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote yet.")

For Loop Example

A for loop repeats a block of code for a specified number of iterations. This example iterates through a list of numbers and prints each one:

numbers = [1, 2, 3, 4, 5]

for number in numbers:
    print(f"The current number is: {number}")

While Loop Example

A while loop repeats code as long as a given condition remains true. The following example prints the current count, starting from 1 and stopping when the count reaches 5:

count = 1

while count <= 5:
    print(f"Count is: {count}")
    count += 1

3. Functions

Functions are reusable blocks of code designed to perform specific tasks. Learning how to write functions is a key skill when starting to program. Functions make your code more modular and easier to debug. Here’s an example of a basic Python function that greets a user:

Function Example

This function takes a user’s name as input and returns a personalized greeting:

def greet(name):
    return f"Hello, {name}!"

# Call the function
print(greet("Alice"))

In this example, the greet function is defined to accept one parameter: name. When called, it returns a greeting using the provided name.
