The choices() method returns multiple random elements from the list with replacement. You can weigh the possibility of each result with the weights parameter or the cum_weights parameter. The elements can be a string, a range, a list, a tuple or any other kind of sequence.
Syntax : random.choices(sequence, weights=None, cum_weights=None, k=1) Parameters : 1. sequence is a mandatory parameter that can be a list, tuple, or string. 2. weights is an optional parameter which is used to weigh the possibility for each value. 3. cum_weights is an optional parameter which is used to weigh the possibility for each value but in this the possibility is accumulated 4. k is an optional parameter that is used to define the length of the returned list.
Note: This method is different from random.choice(). Example:
import random
  
mylist = ["geeks", "for", "python"]
  
print(random.choices(mylist, weights = [10, 1, 1], k = 5))

                    
Note: Every time output will be different as the system returns random elements. Output:
['geeks', 'geeks', 'geeks', 'for', 'for']
Practical application: Print a random list with 6 items.
import random
  
mylist = ["apple", "banana", "mango"]
  
print(random.choices(mylist, weights = [10, 1, 1], k = 6))

                    
Note: The output changes every time as choices() function is used. Output:
['apple', 'banana', 'apple', 'apple', 'apple', 'banana']
