As mentioned earlier, we are going to use Python as the main tool for data analysis. Yay! Well, if you ask me why, Python has been consistently ranked among the top 10 programming languages and is widely adopted for data analysis and data mining by data science experts. In this book, we assume you have a working knowledge of Python. If you are not familiar with Python, it's probably too early to get started with data analysis. I assume you are familiar with the following Python tools and packages:
| Python programming |
Fundamental concepts of variables, string, and data types Conditionals and functions Sequences, collections, and iterations Working with files Object-oriented programming |
| NumPy |
Create arrays with NumPy, copy arrays, and divide arrays Perform different operations on NumPy arrays Understand array selections, advanced indexing... |
