python choice random code example

Example 1: python random

#import random 
import random

names = ['Harry', 'John', 'Smith', 'Larry']

#print random name from names
print(random.choice(names))

#print random integer in a range of numbers
print(random.randint(1, 100)

Example 2: python random

# imports random
import random
# randint generates a random integar between the first parameter and the second
print(random.randint(1, 100))
# random generates a random real number in the interval [0, 1)
print(random.random())

Example 3: random.choice

import random

numberList = [111,222,333,444,555]
print("random item from list is: ", random.choice(numberList))

Example 4: random picker in python

import random
#dictionary
x_dict = {30:60, 20:40,10:20}
key = random.choice(list(x_dict))
print (key)#if you want it to print 30, 20, or 10
print (x_dict[key])#if you want it to print 60, 40, or 20
print (key,"-", x_dict[key])# if you want to print 30 - 60, 20-40,or 10-20

Example 5: select random value from list python

import random

# with replacement = same item CAN be chosen more than once.
# without replacement = same item CANNOT be chosen more then once.

# Randomly select 2 elements from list without replacement and return a list
random.sample(list_name, 2)

# Randomly select 3 elements from list with replacement and return a list
random.choices(set_name, k=3)

# Returns 1 random element from list
random.choice(list_name)

Example 6: random.choice()

import random
l=[1,2,3,4,5,6,7,8,9,0]
random.choice(l)
print(l);
