Here is the code that a student of mine wrote to create a weather app in Python.

import tkinter as tk
import requests

HEIGHT = 500
WIDTH = 600

def test_function(entry):
print(“This is the entry:”, entry)

def format_response(weather):
try:
name = weather[‘name’] desc = weather[‘weather’][0][‘description’] temp = weather[‘main’][‘temp’]

final_str = ‘City: %s nConditions: %s nTemperature (°C): %s’ % (name, desc, temp)
except:
final_str = ‘There was a problem retrieving that information’

return final_str

def get_weather(city):
weather_key = ‘b55e177fb7b4d4f1d2d17f4d71777440’
url = ‘https://api.openweathermap.org/data/2.5/weather’
params = {‘APPID’: weather_key, ‘q’: city, ‘units’: ‘metric’}
response = requests.get(url, params=params)
weather = response.json()

label[‘text’] = format_response(weather)

root = tk.Tk()

canvas = tk.Canvas(root, height=HEIGHT, width=WIDTH)
canvas.pack()

background_image = tk.PhotoImage(file=’landscape.png’)
background_label = tk.Label(root, image=background_image)
background_label.place(relwidth=1, relheight=1)

frame = tk.Frame(root, bg=’#80c1ff’, bd=5)
frame.place(relx=0.5, rely=0.1, relwidth=0.75, relheight=0.1, anchor=’n’)

entry = tk.Entry(frame, font=40)
entry.place(relwidth=0.65, relheight=1)

button = tk.Button(frame, text=”Get Weather”, font=40, command=lambda: get_weather(entry.get()))
button.place(relx=0.7, relheight=1, relwidth=0.3)

lower_frame = tk.Frame(root, bg=’#80c1ff’, bd=10)
lower_frame.place(relx=0.5, rely=0.25, relwidth=0.75, relheight=0.6, anchor=’n’)

label = tk.Label(lower_frame)
label.place(relwidth=1, relheight=1)

root.mainloop()
