Must-know foundational Python skills

In this section, we concentrate on the fundamental Python concepts necessary for data engineering. This entails being familiar with the syntax of Python as well as basic data structures such as lists, tuples, and dictionaries. We’ll look at how to use control structures such as conditional statements, loops, and functions, as well as how to create and use them. The importance of Python’s basic built-in functions and modules will be emphasized, along with its role in creating effective, modular programming.

We’ll finish up by discussing file input/output (I/O) operations, which are crucial for processing data. The overview of these crucial Python foundations in this section will help you get ready for and ace your data engineering interview. It’s not a Python course, but rather a review of the fundamental abilities a data engineer needs.

In the upcoming subsections, the foundational skills have been broken down into...
