Python - Random Module

Functions in the random module depend on a pseudo-random number generator function random(), which generates a random float number between 0.0 and 1.0.

random.random(): Generates a random float number between 0.0 to 1.0. The function doesn't need any arguments.

>>>import random >>>random.random() 0.645173684807533

random.randint(): Returns a random integer between the specified integers.

>>>import random >>>random.randint(1,100) 95 >>>random.randint(1,100) 49

random.randrange(): Returns a randomly selected element from the range created by the start, stop and step arguments. The value of start is 0 by default. Similarly, the value of step is 1 by default.

>>>random.randrange(1,10) 2 >>>random.randrange(1,10,2) 5 >>>random.randrange(0,101,10) 80

random.choice(): Returns a randomly selected element from a non-empty sequence. An empty sequence as argument raises an IndexError.

>>>import random >>>random.choice('computer') 't' >>>random.choice([12,23,45,67,65,43]) 45 >>>random.choice((12,23,45,67,65,43)) 67

random.shuffle(): This functions randomly reorders the elements in a list.

>>>numbers=[12,23,45,67,65,43] >>>random.shuffle(numbers) >>>numbers [23, 12, 43, 65, 67, 45] >>>random.shuffle(numbers) >>>numbers [23, 43, 65, 45, 12, 67]
