Let's say we have a game that ends when a player's HP drops to zero or below. Then we need to check the value of the variable player1_hp and if it is zero or below, we go to the "game over" section in the code. For example, like this:

. Here are two important things about Python: Indentation and Blocks.

In Python code, there are blocks, "chunks", that are executed only under certain conditions. In the example above, the block

It is executed only if the preceding conditional statement is true. The block is identified by the fact that:

It is preceded by a colon at the end of the previous line.

It is indented further to the right from the previous line.

In Python, unlike many other programming languages, indentation actually matters.

In conditional statements, it is also possible to define another block, that is, what happens if the condition is false. This is done using else:

You can actually put as many blocks as you want in conditionals, using elif statements.

If not, and if player1_hp < 10, print "The player is already one foot in the grave".

If not, then reduce until "The player is still in good shape."

Note that these blocks will always lead to only one option.

Write a program that reads a number from the user's input. If the number is less than 5, print "below". If the number is even 5, print "even". And if the number is more than 5, print "over".

## What are conditionals?

Let's say we have a game that ends when a player's HP drops to zero or below. Then we need to check the value of the variable player1\_hp and if it is zero or below, we go to the "game over" section in the code. For example, like this:

```python
player1_hp = 50

if player1_hp <= 0:
  print("Game over")
```

The program works as follows:

- Define a variable **player1\_hp** and assign it the value **50**.
- Checking if the value of **player1\_hp** is less than or equal to (**<=**) **0**.
- If yes, print **"Game over"**.

So **IF SOMETHING** then** DO SOMETHING**. Here are two important things about Python: Indentation and Blocks.

## Indentation and Blocks

In Python code, there are blocks, "chunks", that are executed only under certain conditions. In the example above, the block

```python
    print("Game over")
```

It is executed only if the preceding conditional statement is true. The block is identified by the fact that:

- It is preceded by a colon at the end of the previous line.
- It is indented further to the right from the previous line.

In Python, unlike many other programming languages, indentation actually matters.

## if, else

In conditional statements, it is also possible to define another block, that is, what happens if the condition is false. This is done using else:

```python
player1_hp = 50

if player1_hp <= 0:
  print("Game over")
else:
  print("Player is still alive")
```

---

## **elif**

You can actually put as many blocks as you want in conditionals, using elif statements.

```python
player1_hp = 50

if player1_hp <= 0:
  print("Game over")
elif player1_hp < 10:
  print("The player already has one foot in the grave.")
else:
  print("The player is still healthy.")
```

The above program works as follows:

- If player1\_hp <= 0, output "Game over".
- If not, and if player1\_hp < 10, print "The player is already one foot in the grave".
- If not, then reduce until "The player is still in good shape."

Note that these blocks will always lead to only one option.

---

## Comparison of Numbers

- **>** Greater than.
- **<** Less than.
- **>=** Greater than or equal to.
- **<=** Less than or equal to.
- **==** Equals.

---

## Exercise

Example of how the program should work:

```sh
Enter the number: 5
equally
```

```sh
Enter the number: 3
under
```

```sh
Enter the number: 9
over
```

Let's learn the basics of programming with Python. Aimed at complete beginners.

Welcome to the Python programming course! This course is intended for anyone who wants to learn to program in the Python language but has no previous programming experience. Python is a very popular programming language used in various applications, such as web development, data processing, artificial intelligence, and data analytics.

The aim of the course is to provide you with basic knowledge of Python programming and help you develop your skills step by step. We will go through basic concepts such as variables, conditional statements, and loops, and you will learn how to use Python for data processing.

The course consists of various learning materials, such as videos, written materials, and exercises, that allow you to apply what you have learned in practice. As the course progresses, you will learn more complex programming concepts and techniques and achieve a solid foundation in Python programming.

It is highly recommended to take this course immediately after the basic course, as understanding vulnerabilities is much easier if you understand code. Besides, coding is fun!
