Technical requirements
You can follow the code for this chapter in the Chapter02/first_code.ipynb notebook. No additional packages are required, just Python.
You can find the code via the following link, which is in the GitHub repository in the Chapter02 folder (https://github.com/PacktPublishing/Learn-Python-by-Building-Data-Science-Applications).
Important note: In this and many other chapters, we'll include both snippets of code and interactive shells, similar to what your code will look like in Jupyter. In order to distinguish the code we ran from the output, in every code block that has an interaction, the running code will start after a triple greater than sign ( >>>), similar to how it is present in Python consoles. By the way, you still can copy and paste the code—Jupyter will simply ignore this symbol and will run correctly.
