If this parameter is true, then the next usage of any Python functionality will trigger the initialization of the pandas interface. When the interface is initialized, Mosel scalars can also be initialized from NumPy scalars, arrays can also be initialized from NumPy ndarrays and pandas Series, and lists of arrays can be initialized from pandas DataFrames. Once initialized, the pandas interface will remain initialized even after switching pyusepandas off. In particular, it will still be possible to initialize Mosel types from pandas and NumPy types.
When converting data from Mosel to Python, the target type depends on the value of pyusepandas: When the parameter is true, Mosel arrays and lists of arrays are converted to pandas Series and DataFrames; when it is false, then Mosel arrays will be converted to Python dictionaries. Mosel lists of arrays cannot be initialized to a Python type when this parameter is disabled.
