tecio.dat.Read

class tecio.dat.Read

Bases: object

Read a Tecplot ASCII DAT file into memory.

The entire file is parsed on construction. All data is then available through the same attributes and methods as szl.Read.

Example

>>> dat = Read("Onera.dat")
>>> dat = tecio.open("Onera.dat", "r")

Parameters:

path (str) – Path to the .dat file.

Raises:

• FileNotFoundError – If path does not exist.

• ValueError – On unsupported format features.

__enter__()

Context manager for Read class.

__exit__(exc_type, exc_val, exc_tb)

Context manager protocol for read-only file interfaces.

Read classes hold no open file handle between accesses, so there is nothing to release on exit. Provided for API consistency with the Write classes and to support the with tecio.open(...) as r: pattern.

__init__(path)

__repr__()

Set a nice repr string for the read object.

property auxdata

Return the dataset-level ReadAuxData container.

property file_type

Return FileType enum for this file.

get_var_auxdata(var_index)

Return auxiliary data for variable var_index (1-based).

Example

>>> aux = dat.get_var_auxdata(1)

Raises:

IndexError – If var_index is out of range.

get_zone_auxdata(zone_index)

Return auxiliary data for zone zone_index (1-based).

Example

>>> aux = dat.get_zone_auxdata(1)

Raises:

IndexError – If zone_index is out of range.

property num_auxdata_items

Return the number of dataset-level auxiliary data items.

property num_vars

Return the number of variables in the dataset.

property num_zones

Return the number of zones in the file.

property title
