import matplotlib.pyplot as plt
As a very simple way,
plt.figure() # not even necessary
plt.plot()
plt.xlabel("x-axis")
plt.ylabel("y-axis")
plt.title("title")
plt.show() , plt.savefig("filename")
However, when things get a little more complicated (e.g. if you want to make multiple figures from a single script), you need to specify which figure or which axis you are modifying:
fig, ax = plt.subplots(1, 1) # the number of rows and columns
ax.plot(x, y)
ax.set_xlabel("x-axis")
ax.set_ylabel("y-axis")
fig.savefig()
plt.close(fig)
