import math
real_pi = math.pi # math library provides close approximation of pi
approximate_pi = 22.0 / 7.0 # Approximate pi to 2 decimal places
print('22/7 is accurate for 2 decimal places: %.2f' % approximate_pi)
22/7 is accurate for 2 decimal places: 3.141593
22/7 is accurate for 2 decimal places: 3
22/7 is accurate for 2 decimal places:
22/7 is accurate for 2 decimal places: 3.14
