Welcome to this beginner-friendly Python practice blog! Python is a powerful and versatile programming language that is perfect for both beginners and experienced developers. This blog will walk you through basic Python concepts, such as working with variables, manipulating strings, performing arithmetic operations, and using lists. Each section includes practical examples and explanations to help you learn by doing. Let’s dive in and explore the simplicity and flexibility of Python!
1. Simple Messages
Python makes it easy to store messages in variables and print them. Here’s an example:
message = "Your love is the only reason to wake up every morning."
print(message)
message = "Smile and be happy. Be grateful for all the good things in your life."
print(message)
This demonstrates how you can reassign values to a variable and print the updated message.
2. Name Cases
Manipulating text in Python is straightforward with built-in string methods. Let’s explore changing the case of a name:
name = "Anuradha Rooprai"
print(name)
name = name.upper()
print(name)
name = name.lower()
print(name)
name = name.title()
print(name)
In this example:
.upper()converts the string to uppercase..lower()converts the string to lowercase..title()capitalizes the first letter of each word.
3. Famous Quote
String formatting helps in combining text and variables dynamically:
quote = "I'm a writer, and I will write what I want to write."
author = "J.K.Rowling"
message1 = f"{author} once said,\"{quote}\""
print(message1)
Using f-strings allows you to embed variables directly within your string for better readability and efficiency.
4. Math with Numbers
Python is an excellent tool for performing basic arithmetic operations:
num1 = 27
num2 = 31
add = num1 + num2
print(add)
sub = num1 - num2
print(sub)
multi = num1 * num2
print(multi)
divide = num1 / num2
print(divide)
Here’s what each operation does:
+adds the two numbers.-subtracts one number from another.*multiplies the numbers./divides one number by another.
5. List Practice
Lists in Python allow you to store and manipulate collections of items:
foods = ["Sarson Da Saag", "Bharva Karela", "Curry Chawal", "Chole Bhuture", "Baingan Bharta"]
print(foods[0])
print(foods[2])
print(foods[-1])
foods[2] = "Rajma Chawal"
print(foods)
del foods[2]
print(foods)
foods.append("Rajma Chawal")
print(foods)
foods.remove("Rajma Chawal")
print(foods)
Accessing elements:
foods[0]fetches the first item, andfoods[-1]fetches the last item.Modifying elements: Assigning a new value to an index changes the list.
Deleting elements: Use
delto remove an item by index.Adding elements:
.append()adds an item to the end of the list.Removing elements:
.remove()deletes an item by value.
Conclusion
This practice session covers essential Python concepts like variables, strings, arithmetic operations, and lists. Each example demonstrates the flexibility and simplicity Python offers for beginners to quickly get started. Happy coding!
