3 Data Wrangling & Visualization
You have just learned the basics of Python programming — congrats! Now, let’s learn how to wrangle and visualize data.
This second part of the course covers two external libraries: numpy
and pandas
. Both are essential workhorses of data wrangling with Python. numpy
is a library for scientific computing and many other libraries are built on top of this one. pandas
is a data analysis and manipulation tool and the best choice when working with tabular data. At the end of this lecture we will also introduce and use matplotlib
for simple plotting.
