The shuffle method of random module
The shuffle method of the random module shuffles the order of elements in a mutable sequence. Since a tuple is an immutable sequence and the elements in a set are unordered, it turns out that the method only works with a list. After executing the method, the original list is changed, and the method itself returns None. In the method parameter, we pass the list we need.
Syntax
import random
random.shuffle(list)
Example
Let's shuffle the elements in the list:
lst = [1, 2, 3, 4, 5]
random.shuffle(lst)
print(lst)
Result of code execution:
[4, 3, 2, 1, 5]
Example
Now let's try to shuffle the elements of the tuple:
tpl = ('1', '2', '3', '4', '5')
random.shuffle(tpl)
print(tpl)
We will get the following error back:
TypeError: 'tuple' object does not support item assignment
Example
Let's also try to mix the elements of the set:
st = {'a', 'b', 'c', 'd'}
random.shuffle(st)
print(st)
After executing the code we will get the following error:
TypeError: 'set' object is not subscriptable
