Sometimes, we want to check if all elements in a list are identical in Python.
In this article, we’ll look at how to check if all elements in a list are identical in Python.
How to check if all elements in a list are identical in Python?
To check if all elements in a list are identical in Python, we can convert the list to a set and check whether the set’s length is 1 or shorter.
For instance, we write:
the_list = [1, 1, 1, 1, 1]
all_same = len(set(the_list)) <= 1
print(all_same)
We define the the_list list with all 1’s.
Then we call set with the_list to convert it to a set.
Next, we get the length of the set with len.
And we check that the set’s length is 1 or less than return that.
Finally, we assign the result to all_same.
Therefore, all_same is True.
Conclusion
To check if all elements in a list are identical in Python, we can convert the list to a set and check whether the set’s length is 1 or shorter.
