ExcelRange¶

class ExcelRange(path, range_, sheet=None, keyids=None)[source]¶

Mapping class for accessing Excel ranges

An ExcelRange is a dict-like object that represents a range in an Excel file. The user can read values from the range or write values to it by the subscription operator []. ExcelRange is a mapping class, thus it implements all the mapping methods and operations.

ExcelRange objects can only be created by the Model.new_excel_range or UserSpace.new_excel_range method.

ExcelRange is a subclass of the BaseDataClient abstract class. The dataclients property list all the BaseDataClient instances held in the Model including ExcelRange objects.

PandasData¶

class PandasData(path, data, filetype, is_hidden)[source]¶

A subclass of BaseDataClient that associates a pandas DataFrame or Series with a file

A PandasData holds a pandas DataFrame or Series object, and associates it with a file for writing and reading the object.

A PandasData can be created only by UserSpace.new_pandas or Model.new_pandas.

The DataFrame or Series held in PandasData objects are accessible through value property or a call () method.

Parameters

path – Path to a file for saving data. If a relative path is given, it is relative to the model folder.
data – a pandas DataFrame or Series.
filetype (str) – String to specify the file format. “excel” or “csv”

ModuleData¶

class ModuleData(path, module)[source]¶

A subclass of BaseDataClient that associates a user module with its source file in the model

A ModuleData is created either by UserSpace.new_module or Model.new_module when a user module is assigned to a Reference. The ModuleData is assigned to the _mx_dataclient attribute of the module.
