Chapter 2: Getting Started with Python

2.1 Installing Python

Welcome to Part II of your data analysis journey! In this chapter, we will be transitioning from understanding what data analysis is to actually doing it with Python, our language of choice for this adventure. We understand that some readers may have little to no coding experience, while others may have a bit of experience. Therefore, this chapter aims to set everyone on the same page by providing an in-depth overview of Python basics.  

We'll start by guiding you through the process of installing Python on your system. This will ensure that you have everything you need to get started with data analysis. Next, we will provide an overview of Python's syntax. Python is a simple yet powerful language, and we want to make sure that you are comfortable with it before we dive deeper into data analysis. 

After you are comfortable with Python's syntax, we will introduce you to Python's data structures. These data structures form the building blocks of many data analysis operations, so it's important that you understand them inside and out. We will provide you with hands-on experience by having you write your own Python scripts. This way, you will not only understand the theory behind data analysis but also have practical experience.

So, let's roll up our sleeves, get coding, and take the first step towards becoming a data analyst!

Installing Python is a crucial first step in unlocking its immense potential for data analysis. The process itself is straightforward, but there are several different methods to achieve it. Depending on your specific needs, you may choose to install Python using one of several popular distributions such as Anaconda or Miniconda, which come preloaded with many of the most commonly used Python packages for data analysis.

Alternatively, you could opt to install Python directly from the official website, which provides more options but may require more manual configuration. For the purposes of this book, we will focus on the most direct and commonly used method of installing Python to ensure that you have the necessary tools to succeed in your data analysis journey.

2.1.1 For Windows Users:

  1. Download Installer: Go to the official Python website https://www.python.org/downloads/windows/.
  2. Run Installer: Once downloaded, locate the .exe file and double-click it.
  3. Installation Wizard: During installation, check the box that says "Add Python to PATH" at the bottom. This will allow you to run Python from the Command Prompt.
  4. Finish Installation: Follow the on-screen prompts and click “Install Now.”

Here's how to check if Python was successfully installed:

# Open Command Prompt and type:
python --version

2.1.2 For Mac Users:

  1. Download Installer: Visit https://www.python.org/downloads/mac-osx/.
  2. Run Installer: Locate the downloaded .pkg file and double-click it.
  3. Follow Installation Steps: Continue through the installation wizard, clicking "Continue" or "Agree" as needed.

To verify the installation:

# Open Terminal and type:
python3 --version

2.1.3 For Linux Users:

Python is usually pre-installed on Linux systems. To check:

# Open Terminal and type:
python3 --version

If it's not installed, you can install it via package manager:

# For Ubuntu/Debian
sudo apt-get update
sudo apt-get install python3

# For Fedora
sudo dnf install python3

2.1.4 Test Your Installation

After installation, let's write your first Python script to print "Hello, World!"

# Type this in your preferred editor and save as hello.py
print("Hello, World!")

Run the script:

# Navigate to the folder where hello.py is saved, then type:
python hello.py # Windows
python3 hello.py # Mac/Linux

If you see "Hello, World!" printed on your screen, congratulations! You've successfully installed Python and executed your first script. Now, you're ready to dive deeper into the fascinating world of Python and data analysis.
