Re: Matplotlib exercise

The way I did it is just spread a uniformly-distributed set of points between -1 and 1, then assign them colors depending on their position. # Import required libraries import numpy as np import matplotlib.pyplot as plt # Make 1D arrays for x and y axes and spread them around -1 and 1 x1 = (np.rando...

Re: How did you guys complete the matplotlib exercise

Here's my solution: # Import required libraries import numpy as np import matplotlib.pyplot as plt # Make 1D arrays for x and y axes and spread them around -1 and 1 x1 = (np.random.random(2000)-0.5)*2 x2 = (np.random.random(2000)-0.5)*2 # Make an array for color picking Y = np.zeros(2000) for e in r...

Here's what I have so far: import numpy as np import matplotlib.pyplot as plt import pandas as pd x1 = (np.random.random(2000)-0.5)*30 x2 = (np.random.random(2000)-0.5)*30 A = np.column_stack((x1,x2)) df = pd.DataFrame(A, columns=['x1','x2']) def pwr2(e): return e*e def mult(e,f): return e*f df['x1^...
