text: Python Day 17: Polar Coordinate in Python
  ” You are round and short,
  .
  .
  in polar coordinate.”
  So today we will introduce the most basic calculation in Python for the Polar coordinates.
  z= x+ y*i (x, y in R, i in C)
  Output format:
  first line τ: distance from z to origin.
  second line φ: counterclockwise angle measure from the positive x-axis to the line segment that joins z to the origin.

  Code:
  import cmath a=cmath.polar(complex(1.0,2.0)) print(a,sep="\")
  Output:
  (2.23606797749979, 1.1071487177940904)
  Polar Plot
  import numpy as np import matplotlib.pyplot as plt # Fixing random state for reproducibility np.random.seed(19680801) # Compute areas and colors N = 150 r = 2 * np.random.rand(N) theta = 2 * np.pi * np.random.rand(N) area = 200 * r**2 colors = theta fig = plt.figure() ax = fig.add_subplot(111, projection='polar') c = ax.scatter(theta, r, c=colors, s=area, cmap='hsv', alpha=0.75)
  Happy Practicing!
