how to pick a random element from a list in python code example
Example 1: python choose random element from list
import random
#1.A single element
random.choice(list)
#2.Multiple elements with replacement
random.choices(list, k = 4)
#3.Multiple elements without replacement
random.sample(list, 4)
Example 2: how to print a random part of a list in python
import random
foo = ['a', 'b', 'c', 'd', 'e']
print(random.choice(foo))
Example 3: how to randomly choose from a list python
random.choice(name of list)
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 a random element from a list python
import random
# there are 2 ways for this
listofnum = [1, 2, 3, 4, 5]
# 1
print(random.choice(listofnum))
# 2
random.shuffle(listofnum)
print(listofnum)
Example 6: python choose random sample from list
import random
sequence = [i for i in range(20)]
subset = sample(sequence, 5) #5 is the lenth of the sample
print(subset) # prints 5 random numbers from sequence (without replacement)
