Random Module

Dear Readers,
todays post is on random module

                              Random Module Usage in Python

Importing necessary libraries from random module

from random import random,gauss,randrange,randint,sample,choice,choices,seed

# Use seed to get same random number again and again as the output, without seeding you would get varied output everytime you run the program.

seed(9)

# for getting a random floating number always less than one

print(random())

# for getting intergers we use randint and randrange ,randint(start_value,stop_value) and randrange(start_value,stop_value)

print(randint(0,9))
print(randrange(0,1000))

# get a random choice out of a list or a tuple using choice attribute , you can use choices to get a random sample as an output with specified size

list1 = ['a','b','c','d','e','f','g','h']
print(choice(list1))
print(choices(list1,k=4)) # here k means size of the output/or number of random selections to be made and ouput is in list format

# to get a gaussian number we use , gauss(mean,standard deviation) ['THIS IS OPTIONAL'] 

print(gauss(10,2.5))

# like random choices we can use random sample, like sample(list_name,size)

list2 = [1,2,3,4,5,6,7]
print(sample(list2,4)) # outputs list format only
