**template-dict** - JSON compatible Python dictionary templates. You can use them to fill some schema with data
dynamically. Template dicts support nested data, lists. functions and eval of simple Python data types.
# Installation
With pip and python 3.8+:
```bash
pip3 install template-dict
```
# How to use
See the [user guide](https://template-dict.readthedocs.io/guide.html) for more info.
`Template` objects can be used to fill dictionary-like schema with dynamic data.
Note that these are not Jinja templates but rather a tool to manipulate Python data dynamically.
To create a template you must define a schema and then feed it with some data mapping.
```python
from template_dict import Template
t = Template({'value': '[key.nested]'})
t.eval({'key': {'nested': True}}) # -> {'value': True}
```
Template can accept a string or an iterable as a schema.
```python
t = Template(['[name]', '[name]', '[name]'])
t.eval({'name': 'dogs'}) # -> ["dogs", "dogs", "dogs"]
```
You can access template keys before evaluating it.
```python
t = Template({'value': '[key]'})
t.keys # -> ['key']
```
