Python Code Examples: A Sample Script Coding Tutorial for Beginners

Introduction to Python Code Examples

Python is a versatile programming language that is known for its simplicity and readability. If you’re a beginner in Python programming, learning by example is an effective way to understand the language constructs and develop your coding skills. In this article, we will provide a collection of Python code examples that cover various topics and concepts, serving as a coding tutorial for beginners. Each example is accompanied by an explanation to help you grasp the underlying principles.

Example 1: Hello, World!

Overview of the Example

The first example is the classic “Hello, World!” program. It is a simple script that prints the famous greeting message to the console.

Code Example

print("Hello, World!")

Explanation

This code uses the print() function to display the string “Hello, World!” on the console. The print() function is a built-in Python function that outputs text or variables to the console.

Example 2: Basic Arithmetic Operations

Overview of the Example

The second example demonstrates basic arithmetic operations in Python. It performs addition, subtraction, multiplication, and division.

Code Example

a = 5
b = 3

sum = a + b
difference = a - b
product = a * b
quotient = a / b

print("Sum:", sum)
print("Difference:", difference)
print("Product:", product)
print("Quotient:", quotient)

Explanation

This code defines two variables, a and b, and assigns them the values 5 and 3, respectively. It then performs basic arithmetic operations using these variables and assigns the results to new variables. Finally, it prints the results to the console using the print() function.

Example 3: User Input and Conditional Statements

Overview of the Example

The third example demonstrates how to take user input and use conditional statements to perform different actions based on the input.

Code Example

name = input("Enter your name: ")

if name == "Alice":
    print("Hello, Alice!")
elif name == "Bob":
    print("Hello, Bob!")
else:
    print("Hello, stranger!")

Explanation

This code prompts the user to enter their name using the input() function and stores the input in the variable name. It then uses conditional statements (if, elif, else) to check the value of name and print a corresponding greeting message.

Example 4: Looping with a for Loop

Overview of the Example

The fourth example demonstrates how to use a for loop to iterate over a sequence of items and perform a repetitive action.

Code Example

fruits = ["apple", "banana", "cherry"]

for fruit in fruits:
    print(fruit)

Explanation

This code defines a list of fruits and uses a for loop to iterate over each item in the list. In each iteration, the current fruit is assigned to the variable fruit, and it is printed to the console using the print() function.

Example 5: Creating Functions

Overview of the Example

The fifth example demonstrates how to create and use functions in Python. It defines a function that calculates the factorial of a number.

Code Example

def factorial
