Example of POST vpz/input in Python language¶

For the simulator ‘wwdm.vpz’ whose Id is 266, enter the Python code/instructions in a Python interpreter.

Example illustrating :

‘compact’ as style of presentation,
‘json’ as format,
value ‘all’ as ‘parselect’ (to receive information of all the existing parameters and conditions)
value ‘all’ as ‘outselect’ (to receive information of all the existing output datas and views)

with ‘application/json’ as ‘Content-Type’
