pyset

Purpose
Assign a Mosel value to a global Python variable.
Synopsis
procedure pyset(varname:string,var:boolean|integer|real|string|text|array|list|set)
Arguments
varname 
Global Python variable name
var 
Mosel value to be assigned to Python variable
Example
The following example writes a Mosel array to a Python dictionary and a Mosel list to a Python list: 
declarations
  MosArray: array(set of string) of real
end-declarations

pyset('py_list', [1, 2, 3])    ! Mosel list -> Python list.
pyexec('print("py_list:", py_list)')

MosArray('e') := M_E; MosArray('pi') := M_PI

setparam('pyusepandas', false) ! Mosel array -> Python dictionary.
pyset('py_dict', MosArray)
pyexec('print("py_dict:", py_dict)')

setparam('pyusepandas', true)  ! Mosel array -> Pandas Series.
pyset('pd_series', MosArray)
pyexec('print("pd_series:", pd_series, sep="\n")')
Further information
1. The procedure creates or overwrites the global variable by writing the new value to the attributes of the Python __main__ module. If the variable name is not a valid Python variable identifier the procedure will succeed anyway and write the value to the module attributes using the name specified in varname.
2. The procedure replaces previously existing global variables. It does not update or add data to existing Python structures.
3. See the I/O Driver python Section for more details about type conversions.
