Assignment 2: Write and Execute "Hello, World!"

Task: Write a Python script to print "Hello, World!" on the screen.
Steps:

1.   Open a text editor (e.g., IDLE or Notepad).

2.   Write the following code:

print("Hello, World!")

3.   Save the file as hello.py.

4.   Run the program:

o    Using IDLE: Press F5 or click Run > Run Module.

o    Using the terminal:

python hello.py

Output:

Hello, World!

Explanation:
The print() function outputs the text "Hello, World!" to the screen.

Assignment 3: Understanding Python as an Interpreted Language

Task: Use Python's interactive mode to run commands line-by-line.
Steps:

1.   Open the Python shell by typing python in the terminal.

2.   Type the following commands one at a time:

print("Python is awesome!")

3 + 5

"Hello" + "World"

3.   Observe the results after each command.

Output:

• Python is awesome!
• 8
• HelloWorld

Explanation:
Python executes commands immediately, showing results line-by-line, which is a characteristic of interpreted languages.

Assignment 4: Create a Simple Calculator

Task: Write a Python program to add two numbers.
Steps:

1.   Write the following code:

num1 = 10

num2 = 20

result = num1 + num2

print("The sum is:", result)

2.   Save the file as calculator.py.

3.   Run the program.

Output:

python

CopyEdit

The sum is: 30

Explanation:
The program stores numbers in variables num1 and num2, calculates their sum, and displays the result using print().

Assignment 5: Modify "Hello, World!"

Task: Print your name along with "Hello, World!".
Steps:

1.   Write the code:

name = "John"

print("Hello, World! My name is", name)

2.   Save as hello_name.py.

3.   Run the program.

Output:

Hello, World! My name is John

Explanation:
The variable name holds your name, which is included in the print() statement.

Assignment 6: Understanding Variables

Task: Assign values to variables and print them.
Steps:

1.   Write the code:

x = 5

y = 10

z = x + y

print("Value of x:", x)

print("Value of y:", y)

print("Sum of x and y:", z)

2.   Save as variables.py.

3.   Run the program.

Output:

Value of x: 5

Value of y: 10

Sum of x and y: 15

Explanation:
Variables x and y store integers. The sum is calculated and displayed.

Assignment 7: Using Comments

Task: Add comments to explain the "Hello, World!" program.
Steps:

1.   Write the code:

# This is a simple Python program

# It prints "Hello, World!" to the screen

print("Hello, World!")

2.   Save as comments.py.

3.   Run the program.

Output:

Hello, World!

Explanation:
Comments start with # and are ignored by the Python interpreter.

Assignment 8: Using the Input Function

Task: Take a user’s name as input and greet them.
Steps:

1.   Write the code:

name = input("Enter your name: ")

print("Hello, " + name + "!")

2.   Save as greet_user.py.

3.   Run the program and enter your name when prompted.

Example Input:

Enter your name: Alice

Output:

Hello, Alice!

Explanation:
The input() function takes user input as a string, which is concatenated with a greeting.

Assignment 9: Experiment with String Operations

Task: Concatenate two strings and print the result.
Steps:

1.   Write the code:

string1 = "Python "

string2 = "Programming"

result = string1 + string2

print("Concatenated String:", result)

2.   Save as string_operations.py.

3.   Run the program.

Output:

Concatenated String: Python Programming

Explanation:
The + operator concatenates string1 and string2.

Assignment 10: Understanding Error Messages

Task: Run a program with an intentional error and analyze the error message.
Steps:

1.   Write the code with a missing closing quote:

print("This will cause an error)

2.   Save as error_example.py.

3.   Run the program.

Output:

SyntaxError: EOL while scanning string literal

Explanation:
