Python is one of the most beginner-friendly programming languages in the world. Whether you want to become a data analyst, data scientist, backend developer, automation engineer, or AI engineer, Python is an excellent place to start.

In this first part of the series, you'll learn the fundamentals you need before moving on to decision-making, loops, and functions in Part 2.

Python is known for its simple syntax, making it easy to read and write. It is used in many fields, including:

If you've never written code before, don't worry. We'll take it one step at a time.

Download the latest version of Python from the official website.

During installation on Windows, remember to check **"Add Python to PATH"** before clicking **Install Now**.

To verify your installation, open a terminal and type:

```
python --version
```

or

```
python3 --version
```

If Python is installed correctly, you'll see the installed version number.

Let's start with the classic program.

```
print("Hello, World!")
```

Output:

```
Hello, World!
```

Congratulations! You've written your first Python program.

Variables store information that your program can use later.

```
name = "Alice"
age = 22
height = 1.68
```

You can display them using `print()`

.

```
print(name)
print(age)
print(height)
```

Python has several built-in data types.

```
name = "Alice"      # String
age = 22            # Integer
height = 1.68       # Float
is_student = True   # Boolean
```

Understanding data types helps you write reliable programs and avoid common mistakes.

Programs become more useful when they interact with users.

```
name = input("Enter your name: ")

print("Hello,", name)
```

Example output:

```
Enter your name: Victor
Hello, Victor
```

Python supports arithmetic operators.

```
a = 20
b = 5

print(a + b)
print(a - b)
print(a * b)
print(a / b)
```

You can also calculate remainders using `%`

.

```
print(20 % 3)
```

Output:

```
2
```

Comments explain your code and are ignored by Python.

```
# This is a comment

name = "Alice"
```

By completing this article, you've learned how to:

These are the building blocks you'll use in almost every Python program.

In **Part 2**, we'll make our programs smarter by learning:

`if`

, `elif`

, and `else`

`for`

and `while`

loopsHappy coding, and see you in Part 2!
