Page 2 - Lesson Note-Python Modules and Sorting

math Module

sin, cos and tan takes input in radians and radians function of math converts degree to it’s
equivalent radians.

Predefined pi and e

random Module

random()
• return the next random floating point number in the range
[0.0, 1.0) i.e. 0<=N<1

randint(lower limit, upper limit)
• returns a random integer N such that lower_limit<=N<=upper_limit
• The randint(a,b) function accepts two integer parameters, and both are required.
• Both parameters should be integer

randrange(start, stop [, step])
• Returns a random integer in the range (start, stop, step) as per range function
• The step is a difference between each number in the sequence. The step is optional, and the
default value of the step is 1, start is also optional and if no start it returns a random number
N such that 0<=N<stop
• All parameters should be integer
