Gain insights into Python 3 by learning basic concepts like keywords and data types, and delving into 50 code puzzles that enhance your understanding of classes and functions.

This course acts as a stepping stone to becoming a Python master. Before getting into advanced concepts like classes and functions, the course begins with Python's basic concepts, such as keywords and data types. Later in this course, you'll be going through 50 code puzzles that will teach you different concepts in Python 3.

An Intro to Python 3

# Puzzle 1

Let's start with a basic puzzle that uses the `print()` function.

**What is the output of the following code?**

> **Note**: Your initial Elo rating will be 1000. Enter the output you guessed. Then, press the **Run** button, and your new Elo will be calculated. Don't forget to save your Elo rating every time it is updated, as the updated rating will be used in the next puzzle.

print('hello world')

## `print()`
Via the `print()` function, you connect your program to the outside world. This function, as the name indicates, prints a value to the standard output.

<b>What is standard output? </b></p>
You can think of it as the environment in which your Python program lives. Your standard output is the air around you. Let's say you shout "Ouch!" Every person in your environment can read from your standard output that you just experienced pain.



The data that is printed to the standard output is of type **string**. 
> A string is a sequence of characters.

The string is defined via each of the three following ways: 

* Via the single quote (')

   ```
   'hello world'
    ```

* Double quote (")
    ```
    "hello world"
    ```
* Triple quote (''' and """) 
    ```
    '''hello world'''
        or
    """hello world"""
    ```

In the puzzle, we use the single quote to define our string `'hello world'`.
