## Type Checking Example
``` python
from typing import Union
from type_checker import type_check

# the type defintion to check a value against
type_def = {
"hello": {
"world": int
},
"a_key": str,
"a_list": [
float
],
int: bool,
float: Union[bool, int]
}

# a valid test value
test_value = {
"hello": {
"world": 1
},
"a_key": "this_is_a_string",
"a_list": [
3.2,
4.7
5.9
],
5: True,
5.2: False,
5.7: 10

}

# use validate from the type_checker package to validate the value
is_valid = type_check(test_value, type_def)

print(f"is valid: {is_valid}")
```

``` text
$ python example.py
>>> is valid: True
```
