Requirements:

• Create a header for your program just as you have in the past.
• Create a Python Application which asks the user for their zip code or city.
• Use the zip code or city name in order to obtain weather forecast data from OpenWeatherMap.
• Display the weather forecast in a readable format to the user.
• Use comments within the application where appropriate in order to document what the program is doing.
• Use functions including a main function.
• Allow the user to run the program multiple times to allow them to look up weather conditions for multiple locations.
• Validate whether the user entered valid data. If valid data isn’t presented notify the user.
• Use the Requests library in order to request data from the webservice.
  • Use Try blocks to ensure that your request was successful. If the connection was not successful display a message to the user.
• Use Python 3
• Use try blocks when establishing connections to the webservice. You must print a message to the user indicating whether or not the connection was successful

Url: 'http://samples.openweathermap.org/data/2.5/weather?'+key+'&appid=b1b15e88fa797225412429c1c50c122a1'

This is can be found in the OpenWeather site, it's a  demo URL.

the api key used is default provided by the site.

the key parameter contains the user zip code or city name as requested in the question.

import requests
import json

country_code = 'IN'
while True:
  
input1 = input('Enter zip code or City name: ')
  
if input1.isdigit():
key = f"zip={input1},{country_code}"
else:
key = f'q={input1},{country_code}'
  
request_url = 'http://samples.openweathermap.org/data/2.5/weather?'+key+'&appid=b1b15e88fa797225412429c1c50c122a1'
print(request_url)
  
print('requesting...')
request = requests.get(request_url)
  
if request.status_code == 200:
print('sucessfull received data')
#request.text contains data in json format
#using json.loads() that converts data to python dict.
data = json.loads(requet.text)
  
print('OUTPUT::')
  
print('name',data['name'])
print('temperature',data['main']['temp'],'in fahrenheit')
print('wind speed',data['wind']['speed'],'deg',data['wind']['deg'])
print('pressure',data['main']['pressure'])
print('humidity',data['main']['humidity'])
print('cordinates',data['coord'])
print('clouds',data['clouds'])
print('weather',data['weather'][0]['main'])
print('weather description::',data['weather'][0]['description'])
else:
print(request.status_code)
print(request.text)
  
  

output:
