Converted examples in gallery to use pyplot API instead of deprecated pylab API.
I contributed to the matplotlib enhancement proposal 12, which proposed reorganizing the examples gallery to make it easier for matplotlib users to find relevant examples.
Part of the problem was that there were old pylab examples, but the new pyplot API was now preferred over the old pylab API (which was really present mostly to convert MATLAB users). I helped fix all the pylab examples by changing
from pylab import *
statements to explicit
import matplotlib.pyplot as plt import numpy as np
This was my very first open source contribution, and was basically 70+ pull requests to the library. That mechanical repetition helped me get very familiar with git and continuous integration, and showed me the importance of software skills in data work.
