Dear Tango-Dancers,
I am wondering about this behaviour:
I am writing a device property in JSON format via pyTango:


attr_str ='''
            {
                ‘name": “demo_spectrum”,
                ‘dtype": “uint16”,
                ‘dformat": “SPECTRUM”,
                ‘writetype": “READ_WRITE”,
                ‘max_dim_x": 2100,
                ‘timediff": 0.8,
                ‘trigger_timeout": 1.2,
                ‘pv_timeout": 1.2
            }
        '''

db = database()
db.put_device_property( self.get_name(), {f ‘pv_{attr_name}’: attr_str } )

Reading and parsing in a JSON object works perfectly.

pv_props = db.get_device_property_list(‘test/lvproxy/1’, ‘pv_*’).value_string
for p in pv_props:
    json_str = db.get_device_property(‘test/lvproxy/1’, p)[p]
    print(json_str)
>>>
[' \n            {\n                "name": "demo_spectrum", \n                "dtype": "uint16",\n                "dformat": "SPECTRUM",        \n ….

However, when I do a manual edit in JIVE, I get an array of strings separated at ‘\n’ positions:

[' ', '            {', '                "name": "demo_spectrum", ', '                "dtype": "uint16",', '                "dformat": "SPECTRUM",        ', ' …


Of course, I can solve this problem simply by 
'\n'.join(str_array)
, but this behaviour is still not intuitive for me.
