# Example 4: Save information
This module contains an example how to save buildings from a TEASER
project to json and pickle in order to save information.
You can run this example using the [jupyter-notebook](https://mybinder.org/v2/gh/RWTH-EBC/TEASER/main?labpath=docs%2Fjupyter_notebooks)

```python
import teaser.examples.e1_generate_archetype as e1
import teaser.logic.utilities as utilities
import os
```

In e1_generate_archetype we created a Project with three archetype
buildings to get this Project we rerun this example

```python
prj = e1.example_generate_archetype()
```

First option is to use TEASERs own json format to save all relevant
data into a more or less human readable format. The corresponding
function is called Project().save_project() you can specify a file name
and a save path. If both are non (as in this case) it will use the
projects name and default path in your home folder.

```python
prj.save_project(file_name=None, path=None)
```

Second option is to use pickle from Python Standard Library ,
which will save the whole Python classes and all attributes into a
binary file. There is no specific API function for this, but you can
simply create an empty file with open() and then use pickle.dump().
Make sure you specify your path correctly. In this case we want to use
the default path of TEASERs output.

```python
import pickle

pickle_file = os.path.join(utilities.get_default_path(), "teaser_pickle.p")

pickle.dump(prj, open(pickle_file, "wb"))
```
