Python has a simple and straight forward approach to programming math and numbers—if you are OK with high school math, you will be OK with Python math.
Carrying on from earlier examples, here are a few more using the Python interactive interpreter (don’t type in the comments, I have added them for your information only):
>>> 50 - 5*6 # Mathematical precedence 20 # PEMDAS, BEDMAS or BODMAS >>> (50 - 5) * 6 # depending which country you're from 270 >>> 2**10 # Power functions 1024 >>> import math # Python math module >>> r = 10 >>> area = math.pi*(r**2) # Using pi >>> area 314.1592653589793 >>> math.cos(math.radians(60)) # Trigonometry 0.5000000000000001 >>> math.log(256,2) # logarithms 8.0 >>> import random # Python random module >>> random.random() 0.5362880665009504 >>> random.randrange(12) 11 >>> random.randrange(12) 4 >>>
Here’s a screenshot of the complete exercise:
There are dozens more functions you can use to do math and manipulate numbers in Python. For a list of all math functions, check out the Python documentation.
