Sometimes, we want to check if a list is sorted or not with Python.

In this article, we’ll look at how to check if a list is sorted or not with Python.

How to check if a list is sorted or not with Python?

To check if a list is sorted or not with Python, we can use the all function.

For instance, we write

is_sorted = all(l[i] <= l[i+1] for i in range(len(l) - 1))

to call all to check if every item in list l is sorted.

We use range to return an iterator with the index of l from 0 to len(l) - 2.

And check if the next item is bigger than the current one with

l[i] <= l[i+1]

Conclusion

To check if a list is sorted or not with Python, we can use the all function.
