Python | Find current weather of any city using openweathermap API

openweathermap is a service that provides weather data, including current weather data, forecasts, and historical data to the developers of web services and mobile applications.

It provides an API with JSON, XML and HTML endpoints and a limited free usage tier. Making more than 60 calls per minute requires a paid subscription starting at USD 40 per month. Access to historical data requires a subscription starting at 150 USD per month. Users can request current weather information, extended forecasts and graphical maps (showing cloud cover, wind speed, pressure and precipitation).

To use this current weather data API, one must need the API key, which can be get form here.

Note: User need to create an account on openweathermap.org then only can use the APIs.

Modules Needed :

requests
json

 
Below is the implementation :

# Python program to find current 
# weather details of any city
# using openweathermap api
  
# import required modules
import requests, json
  
# Enter your API key here
api_key = "Your_API_Key"
  
# base_url variable to store url
  
# Give city name
city_name = input("Enter city name : ")
  
# complete_url variable to store
# complete url address
complete_url = base_url + "appid=" + api_key + "&q=" + city_name
  
# get method of requests module
# return response object
response = requests.get(complete_url)
  
# json method of response object 
# convert json format data into
# python format data
x = response.json()
  
# Now x contains list of nested dictionaries
# Check the value of "cod" key is equal to
# "404", means city is found otherwise,
# city is not found
if x["cod"] != "404":
  
    # store the value of "main"
    # key in variable y
    y = x["main"]
  
    # store the value corresponding
    # to the "temp" key of y
    current_temperature = y["temp"]
  
    # store the value corresponding
    # to the "pressure" key of y
    current_pressure = y["pressure"]
  
    # store the value corresponding
    # to the "humidity" key of y
    current_humidiy = y["humidity"]
  
    # store the value of "weather"
    # key in variable z
    z = x["weather"]
  
    # store the value corresponding 
    # to the "description" key at 
    # the 0th index of z
    weather_description = z[0]["description"]
  
    # print following values
    print(" Temperature (in kelvin unit) = " +
                    str(current_temperature) + 
          " atmospheric pressure (in hPa unit) = " +
                    str(current_pressure) +
          " humidity (in percentage) = " +
                    str(current_humidiy) +
          " description = " +
                    str(weather_description))
  
else:
    print(" City Not Found ")

Output :

 Enter city name : Delhi
 Temperature (in kelvin unit) = 312.15
 atmospheric pressure (in hPa unit) = 996
 humidity (in percentage) = 40
 description = haze
