Weather App Using API

We will discuss creating a weather application using tkinter. The GUI app will provide information about temperature, latitude, longitude, date, time, year, country of origin, and other details about the current weather of a particular city.

📋 Modules Request:

  1. Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit.

  • Creating a GUI application using Tkinter is an easy task. All you need to do is perform the following steps −

    1. Import the Tkinter module.

    2. Create the GUI application main window.

    3. Add one or more of the above-mentioned widgets to the GUI application.

    4. Enter the main event loop to take action against each event triggered by the user.

  1. Requests: The requests library is the de facto standard for making HTTP requests in Python. It abstracts the complexities of making requests behind a beautiful, simple API so that you can focus on interacting with services and consuming data in your application.
    pip install requests 📋 Approach:
  • First, we need to use a weather API (Application Programming Interface) to fetch data from the Open Weather Map website, and then we need to make a configuration file to store the API key. Finally, we use that configuration file in the Python script.

📋 Steps to generate an API key:

  1. Login in the Open Weather Map
  2. Go to the API section. Then in the Current Weather Data section click on the Api doc.
  3. Now in the API Call section, we have the link of api.openweathermap.org/data/2.5/weather?q={city name}&appid={API key}
  4. Click on the API key on the link it will direct to the page from where you can get the key.

📋 Steps to create the python3 -- Weather Application using API

📌 Importing the libraries:

from tkinter import *
import requests
import json
import datetime
from PIL import ImageTk, Image

📌 Interface of the Application:

root = Tk()
root.title("Weather App")
root.geometry("500x500")
root['background'] = "white"

📌 Dates:

dt = datetime.datetime.now()
date = Label(root, text=dt.strftime('%A  '), bg='white', font=("Bold", 15))
date.place(x=15, y=130)
month = Label(root, text=dt.strftime('%m %B'), bg='white', font=("Blod", 15))
month.place(x=100, y=130)

📌 Time:

hour = Label(root, text=dt.strftime('%I : %M %p'),
			bg='white', font=("bold", 15))
hour.place(x=15, y=160)

📌 Theme for the respective time the application is used:

if int((dt.strftime('%I'))) >= 8 & int((dt.strftime('%I'))) <= 5:
	img = ImageTk.PhotoImage(Image.open('moon.png'))
	panel = Label(root, image=img)
	panel.place(x=210, y=200)
else:
	img = ImageTk.PhotoImage(Image.open('sun.png'))
	panel = Label(root, image=img)
	panel.place(x=210, y=200)

📌 City Search

city_name = StringVar()
city_entry = Entry(root, textvariable=city_name, width=45)
city_entry.grid(row=1, column=0, ipady=10, stick=W+E+N+S)

📌 The function where the API calls:

def city_name():

	# API Call
	api_request = requests.get("https://api.openweathermap.org/data/2.5/weather?q="
							+ city_entry.get() + '&APPID=b35975e18dc93725acb092f7272cc6b8&units=metric')

	api = json.loads(api_request.content)

	# Temperatures
	y = api['main']
	current_temprature = y['temp']
	humidity = y['humidity']
	tempmin = y['temp_min']
	tempmax = y['temp_max']

	# Coordinates
	x = api['coord']
	longtitude = x['lon']
	latitude = x['lat']

	# Country
	z = api['sys']
	country = z['country']
	citi = api['name']

📌 Adding the received info into the screen

	lable_temp.configure(text=current_temprature)
	lable_humidity.configure(text=humidity)
	max_temp.configure(text=tempmax)
	min_temp.configure(text=tempmin)
	lable_lon.configure(text=longtitude)
	lable_lat.configure(text=latitude)
	lable_country.configure(text=country)
	lable_citi.configure(text=citi)

📌 Search Bar and Button:

city_nameButton = Button(root, text="Search", command=city_name)
city_nameButton.grid(row=1, column=1, padx=5, stick=W+E+N+S)

📌 Country Names and Coordinates:

lable_citi = Label(root, text="...", width=0,
				bg='white', font=("bold", 15))
lable_citi.place(x=15, y=63)

lable_country = Label(root, text="...", width=0,
					bg='white', font=("bold", 15))
lable_country.place(x=180, y=63)

lable_lon = Label(root, text="...", width=0,
				bg='white', font=("Helvetica", 15))
lable_lon.place(x=15, y=95)
lable_lat = Label(root, text="...", width=0,
				bg='white', font=("Helvetica", 15))
lable_lat.place(x=180, y=95)

📌 Current Temperature:

lable_temp = Label(root, text="...", width=0, bg = "White",
				font=("Hahmlet",55), fg='black')
lable_temp.place(x=18, y=250)

📌 Other temperature details:

humi = Label(root, text="Humidity : ", width=0,
			bg='white', font=("bold", 15))
humi.place(x=15, y=400)

lable_humidity = Label(root, text="...", width=0,
					bg='white', font=("bold", 15))
lable_humidity.place(x=107, y=400)


maxi = Label(root, text="Max.Temp. : ", width=0,
			bg='white', font=("bold", 15))
maxi.place(x=15, y=430)

max_temp = Label(root, text="...", width=0,
				bg='white', font=("bold", 15))
max_temp.place(x=128, y=430)


mini = Label(root, text="Min.Temp. : ", width=0,
			bg='white', font=("bold", 15))
mini.place(x=15, y=460)

min_temp = Label(root, text="...", width=0,
				bg='white', font=("bold", 15))
min_temp.place(x=128, y=460)

📌 The main event loop to take action against each event triggered by the user:

root.mainloop()
