# `pymcnp.types` Subpackage

`pymcnp.types` contains parsers for basic types, such as integers, zaids, and surface geometry formulas. PyMCNP
implements classes for types to integrate them into the object-oriented recursive decent parsers.

## AST Classes

PyMCNP represents types with AST classes. These AST class have methods for translating
between PyMCNP and MCNP:

* `from_mcnp`. Parses MCNP source, checking for syntax and semantic errors.
* `to_mcnp`. Generates MCNP source from PyMCNP objects, reformatting.
