Sometimes, we want to generate set partitions in Python.

In this article, we’ll look at how to generate set partitions in Python.

### How to generate set partitions in Python?

To generate set partitions in Python, we can use the `more_itertools`

module.

For instance, we write:

```
pip install more-itertools
```

Then we write:

```
import more_itertools as mit
lst = [1, 2, 3]
partitions = [
part for k in range(1,
len(lst) + 1) for part in mit.set_partitions(lst, k)
]
print(partitions)
```

We use list comprehension with `mit.set_partitions(lst, k)`

to create partitions by dividing it with `k`

as the boundary.

It returns the `part`

list which has the partition with `k`

as the boundary.

And we return a nested list with all the partitions with different values of `k`

from 1 to `len(lst)`

.

Therefore, `partitions`

is `[[[1, 2, 3]], [[1], [2, 3]], [[1, 2], [3]], [[2], [1, 3]], [[1], [2], [3]]]`

.

### Conclusion

To generate set partitions in Python, we can use the `more_itertools`

module.
