 Notes/Homework

 1. Install Python
- **Linux & macOS users:** Python should already be installed.
 Check with `python --version`. Upgrade if below version 2.3.
- **Windows users:** Download Python 
from [python.org](https://www.python.org/).
 Run IDLE (Python GUI) after installation.

 2. Reading
- Read **Sections 1.1-1.2, 1.8-1.9, and Chapter 2** of the textbook.

 3. Writing Programs
- A program is a set of instructions for a computer to execute.
- Example program:

  ```python
  print("Hello World!")
  print("How are you?")

Output:

Hello World!
How are you?

Task: Write a program that prints a tic-tac-toe board:
```
print("| |\n| |\n| |")
```
Expected Output:
```
| |
| |
| |
```



    **4. Interpreter Mode**
- Run `python` in terminal (Linux/macOS) or start IDLE (Windows).
- Example:
  ```python
  print("Test message")


   **5. Variables**
- Variables store information.
- Example:
```python
a = "Hello World!"
print(a)

Output:

Hello World!

```

Variables can be updated:

a = "Hello World!"
a = "Goodbye.."
print(a)

Output:

Goodbye..

Task: Write a program that assigns values to a variable and prints them:
```
a = 5
print(a)
a = 7
print(a)
```
Expected Output:
```
5
7
```
```
**6. Operators**
```
Basic arithmetic:
```
a = 5 + 7
print(a)  # Output: 12
```

Complex expressions:

a = (3 + 4 + 21) / 7
b = (9 * 4) / (2 + 1) - 6
print((a * b) - (a + b))  # Output: 14

String concatenation:

print("Hello" + " World")  # Output: Hello World

Task: Predict the output of the following:

print(13 + 6)  # Output: _____
print(2 ** 3)  # Output: _____
print(2 * (1 + 3))  # Output: _____
print(8 / 9)  # Output: _____
print("13" + "6")  # Output: _____
print("13" + 6)  # Output: _____ (Error?)



**7. Review**

What is a program? How to write them.
Using interpreter mode for quick tests.
Variables store different types of information (Boolean, Integer, Float, String).
Operators: Arithmetic (+, -, *, /, **) and their precedence.
String operations: Concatenation.

This concludes Session 1. Happy coding! 🚀
