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.

static from_mcnp(source: str)

Generates Designator from MCNP.

Parameters:

source – MCNP for Designator.

Returns:

Designator.

Raises:

TypesError – SYNTAX_TYPE.

to_mcnp() → str

Generates MCNP from Designator.

Returns:

MCNP designator.
