Welcome folks today in this post we will be building weather application using open weather map api in tkinter. All the source code of application is given below.

Get Started

In order to get started we need to install python inside our system. And now we need to install tkinter library by using the pip command

pip install tkinter

And now we need to make an app.py file inside the root directory and copy paste the below code

And now you need to have a open weather map api and get an api key like this as shown below.

And now copy paste the api key inside this below code inside the file app.py

app.py

from tkinter import *
import tkinter as tk
from datetime import datetime
from PIL import ImageTk , Image
import requests
from tkinter import messagebox

class Weather():


        def weather_report(self):
                
                self.url = "http://api.openweathermap.org/data/2.5/weather?q="
                self.cityname =  self.loc.get(1.0,END)
                self.api_key = '64f61566457c1a48b4f301389ba59786'
                self.data = requests.get(self.url+self.cityname+'&appid='+self.api_key).json()
                

                if self.data['cod'] == '404':
                        messagebox.showerror('Error','City Not Found !!')
                else:
                         self.location['text'] = self.data['name'] + "," + self.data['sys']['country']
                         self.c = self.data['main']['temp_max'] - 273.15
                         self.f = self.c*9/5+32
                         self.weather['text'] = self.data['weather'][0]['main']
                         self.weather['font'] = ('verdana',20,'bold')
                         self.temperature['text'] = f'{self.c}°C \n {self.f}°F'
                         self.temperature['font'] = ('verdana',15,'bold')
                         self.humidity['text'] = self.data['main']['humidity']
                         self.humidity['font'] = ('verdana',15,'bold')
                         self.pressure['text'] = self.data['main']['pressure']
                         self.pressure['font'] = ('verdana',15,'bold')

                self.root.mainloop()









if __name__ == '__main__':

        Weather()

And now if you execute the application by executing the below command

python app.py
