        "rainfall": "0.00",
        "windspeed": "2.9",
        "wdc_I": "C",
        "wdc_II": "W",
        "weathercon_I": "1",
        "weathercon_II": "1",
        "rh_I": "94.0",
        "rh_II": "58.0",

json_data=r.json()

## Print dictionary
dataJson=r.json()
for x in dataJson:
    for key,val in x.items():
    	print key, " => ", val
Output:
