Definition and Usage

The shuffle() method takes a sequence, like a list, and reorganize the order of the items.

Note: This method changes the original list, it does not return a new list.

random.shuffle(sequence)

Parameter	Description
sequence	Required. A sequence.
function	Deprecated since Python 3.9. Removed in Python 3.11. Optional. The name of a function that returns a number between 0.0 and 1.0. If not specified, the function `random()` will be used

This example uses the function parameter, which is deprecated since Python 3.9 and removed in Python 3.11.

You can define your own function to weigh or specify the result.

If the function returns the same number each time, the result will be in the same order each time:

import random

def myfunction():
return 0.1

mylist = ["apple", "banana", "cherry"]
random.shuffle(mylist, myfunction)

print(mylist)
