Hello fellow data engineers! Today, we'll be talking about the top Python libraries that are "essential" for data engineering. If you're new to data engineering or just looking to level up your skills, then you've come to the right place.
What is a Python Library?
First, let's start with what a Python library is. In simple terms, a Python library is a collection of pre-written code that developers can use to perform specific tasks. Python has a vast library ecosystem, and data engineers use various libraries to make their job easier and more efficient.
Now, let's dive into the top 10 Python libraries that data engineers use:
Top 5 Popular Python Libraries:
- Pandas
- Numpy
- Matplotlib
- Scikit-Learn
- TensorFlow
Top 5 Less Popular but Most Useful Python Libraries:
- PySpark
- Dask
- Apache Airflow
- Bokeh
- Plotly
Breakdown
Now, let's explore each of these libraries in more detail:
-
Pandas
- Pandas is a popular Python library used for data manipulation and analysis. It provides tools for working with structured data, including data frames and series.
-
