complete_url = base_url + "appid=" + api_key + "&q=" + city_name 


response = requests.get(complete_url) 


x = response.json() 


if x["cod"] != "404": 

y = x["main"] 


current_temperature = y["temp"] 

current_pressure = y["pressure"] 


current_humidiy = y["humidity"] 


z = x["weather"] 

weather_description = z[0]["description"] 


print(" Temperature (in kelvin unit) = " +
                str(current_temperature) + 
      "\n atmospheric pressure (in hPa unit) = " +
                str(current_pressure) +
      "\n humidity (in percentage) = " +
                str(current_humidiy) +
      "\n description = " +
                str(weather_description))
