### Parse and display a Library

Source: https://skywater-pdk.readthedocs.io/en/main/python-api/skywater_pdk.html

Use `Library.parse` to create a Library object from a library name. This example shows parsing a standard library and accessing its properties.

```python
>>> l = Library.parse("sky130_fd_sc_hd")
>>> l
Library(node=LibraryNode.SKY130, source=LibrarySource('fd'), type=LibraryType.sc, name='hd', version=None)
>>> l.fullname
'sky130_fd_sc_hd'
>>> l.source.fullname
'The SkyWater Foundary'
>>> print(l.type)
Standard Cells
```

### Parse and display a Cell with a library

Source: https://skywater-pdk.readthedocs.io/en/main/python-api/skywater_pdk.html

Source: https://skywater-pdk.readthedocs.io/en/main/python-api/skywater_pdk.html

Shows how to create and inspect numeric cell size variants.

```python
>>> s1 = CellSizeNumeric.from_suffix("_1")
>>> s2 = CellSizeNumeric.from_suffix("_2")
>>> s3 = CellSizeNumeric.from_suffix("_3")
>>> CellSizeNumeric.from_suffix("_-1")
Traceback (most recent call last):
    ...
InvalidSuffixError: Invalid suffix: _-1
>>> s1
CellSizeNumeric(units=1)
>>> s2
CellSizeNumeric(units=2)
>>> s3
CellSizeNumeric(units=3)
>>> str(s1)
'with size of 1 units'
>>> str(s2)
'with size of 2 units'
>>> str(s3)
'with size of 3 units (invalid?)'
>>> s1.describe()
'of 1 units'
>>> s2.describe()
'of 2 units'
>>> s3.describe()
'of 3 units (invalid?)'
>>> s1.suffix
'_1'
>>> s2.suffix
'_2'
>>> s3.suffix
'_3'
