Matplotlib subplots with TeX rendering: good figure baseline for publications
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
fig = plt.figure(figsize=(8.5,11.0))
plt.rc('text', usetex=True)
plt.rc('font', family='serif')
plt.rcParams['text.latex.preamble'] = [r'\boldmath']
# data in xmn, ymn does not exist. Replace with whatever data you're trying to plot

Quick 3d plot snippet for 4 series on the same plot
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
# generally, it's not advised to make 3d plots becuase they're not very transferable
# and there's usually ways to do dimensionality reduction. However, sometimes it's useful
# for exploratory purposes.
fig = plt.figure(figsize=(14,9.5))
ax = fig.add_subplot(111, projection='3d')
ax.scatter(x1, y1, z1, label='data1', c='k')

Get the key with the maximum value in a dictionary
some_dict = {'one': 1, 'two':2, 'three': 3480394803840, 'four': 4}
max_key = max(some_dict, key=some_dict.get)
