Today, we're going to enhance our Python skills by writing a program that prints your name and age. Can anyone tell me what function we can use for printing in Python?
Is it the `print()` function?
Exactly! The `print()` function outputs text to the console. Let's write a simple program: `print('Your Name, Your Age')`. Now, who's ready to try it with their own values?
If I wanted to print my name, how would that work?
Great question! Just replace 'Your Name' with your name, like this: `print('Alice, 20')`. Why don't you give it a shot?
In this session, we will learn how to take user input. Who can tell me the function we use to get input from a user?
I think it's `input()`?
Correct! The `input()` function lets us capture user data. Now we'll write a program to add two numbers. Can anyone outline the steps to achieve this?
First, we can ask for the first number, then the second, and finally we need to print their sum.
Well done! Remember to convert the input to integers. So, after collecting the input, use `int()` to convert, like this: `int(input('Enter the first number: '))`. Let's write the program together.
Now, let's create a program that checks if a number is even or odd. Can someone remind me how we can use conditional statements in Python?
We'll use `if` and `else` statements!
Exactly! We can check the remainder when dividing by 2. If it's 0, the number is even. We'll write this as `if number % 2 == 0:`. Now, who wants to write this logic in the code?
I can do it! So we ask for a number and then check it, right?
Perfect! Let's code this together and ensure we print whether the number is even or odd.
Next up is using loops! Who here is familiar with the `for` loop?
We can use it to repeat actions, right? Like printing numbers?
Exactly! Let's write a `for` loop that prints numbers from 1 to 10. What does our loop might look like?
I think we should use `for i in range(1, 11):` and then print `i`.
You're spot on! Let's implement that code, and I want everyone to run it and see the numbers printed.
Finally, let’s talk about lists. How do we define a list of fruits in Python?
We can use square brackets, like `fruits = ['apple', 'banana', 'cherry']`.
Exactly! And how can we print the third fruit from this list?
Use `print(fruits[2])` since the index starts at 0!
That's correct! Let's code this up and see the output together.

Practice programs are essential for reinforcing learning in Python. This section includes exercises focused on printing output, taking user input, and working with loops and lists, aimed at solidifying the expertise of beginners in Python programming.
In the Practice Programs section, readers engage with a variety of programming exercises to reinforce the concepts introduced earlier in the chapter about Python. Each program is designed to be simple yet effective, covering fundamental skills such as printing output, manipulating variables, and using control structures like loops and conditionals. The exercises include:
print()
function.These exercises collectively help students practice their coding skills while instilling confidence in their ability to write simple programs.

This exercise encourages you to create a simple program that outputs your name and age. To do this, you can use the print() function in Python. For example, if your name is 'Alice' and your age is '14', you would write:
print("My name is Alice.") print("I am 14 years old.")
When you run the program, it will display your name and age on the screen.
Think of this like introducing yourself in a group. Just as you would say, 'Hi, I’m Alice and I’m 14 years old,' your Python program does the same but in a digital format.

This program involves taking two numbers from the user and calculating their sum. You can use the input() function to get user input. For instance:
# Taking user input num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) # Calculating sum sum = num1 + num2 # Displaying result print("The sum is:", sum)
This will prompt the user to enter two numbers and then display the result of their addition.
Imagine you are at a shop where two people tell you how much money they have. If you are asked to find out the total amount they have, you would just add the two amounts together. Similarly, the program adds two numbers given by the user.

This program checks if a number entered by the user is even or odd using the modulo operator (%). An even number is divisible by 2, while an odd number is not. Here's how you can write this:
# Taking input number = int(input("Enter a number: ")) # Checking if it's even or odd if number % 2 == 0: print("The number is even.") else: print("The number is odd.")
The % operator here determines whether there is a remainder when the number is divided by 2.
Think of the concept of even and odd numbers like splitting something into pairs. If you can divide the items equally into pairs without any leftover, it's even. If there's one item left over, it's odd.

This task requires you to use a loop to print numbers sequentially from 1 to 10. A for loop is ideal for this:
for i in range(1, 11): print(i)
The range(1, 11) creates a sequence of numbers from 1 to 10, and the loop iterates through each number, printing it.
Imagine counting how many cookies you have, one by one. You start from 1 and go up to however many cookies there are—in this case, 10. The loop does exactly that, going through each number step by step.

This exercise involves creating a list, which is an ordered collection of items. After creating the list with five fruits, you access the third item using its index (remember, Python uses zero-based indexing). Here's how you can do it:
fruits = ["apple", "banana", "cherry", "date", "elderberry"] print(fruits[2])
In this case, 'cherry' is at index 2 and will be printed.
Think of the list of fruits like a fruit basket. If you want to pick the third fruit, you might count each fruit one by one until you reach the third. In programming, this counting is done using indexes.

Key Concepts
Printing Output: Use the print()
function to display information.
User Input: The input()
function captures input from the user.
Even or Odd: Use conditionals to determine if a number is even or odd.
Loops: Use for
loops to iterate through sequences.
Lists: Create ordered collections of items using lists.
See how the concepts apply in real-world scenarios to understand their practical implications.
Example for printing: print('Alice, 20')
outputs Alice's name and age.
Example for summing two numbers: num1 = int(input('Enter first number: ')); num2 = int(input('Enter second number: ')); print(num1 + num2)
.
Use mnemonics, acronyms, or visual cues to help remember key information more easily.
Print to show, Input to go, Even for balance, Odd to throw!
Once there was a programmer who could print the name of every fruit he ate. With print()
, his story began, and he eagerly awaited the user's input to add to his list!
