Interpreters#

There are several ways to use the xara package:

To execute Tcl procedures from a Python script, just create an instance of the xara.Model class and call its eval() method:
```
model = xara.Model()
model.eval("model Basic -ndm 2")
model.eval("node 1 0.0 0.0")
```
To start an interactive interpreter run the shell command:
```
python -m xara
```
To quit the interpreter, just run exit:
```
opensees > exit
```
The xara package exposes a compatibility layer that exactly reproduces the OpenSeesPy functions, but does so without mandating a single global program state. To run OpenSeesPy scripts, just change the import:
```
import openseespy.opensees
```
to
```
import opensees.openseespy
```
