Question

*** Using Python ***

Your program must prompt the user for their city or zip code and request weather forecast data from openweathermap.org. Your program must display the weather information in an READABLE format to the user.

Requirements:

• 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: http://openweathermap.org/
• 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.
• 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 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.

Important: First get your api key from openweathermap.org/ and paste it in line 9 in the code below,

Code

import requests

# make call to weboste and fetch data

def get_web_data(zip=None, city=None):
baseUrl = "http://api.openweathermap.org/data/2.5/weather?units=imperial"
# api id for the site
apiid = "" #enter api code here

# check if the suer gave the zip code or the city name
if zip is not None:
# us at the end id for usa country , change it as required
baseUrl += "&zip="+str(zip)+",us"
else:
baseUrl += "&q="+str(city)+",us"
# finally append the api id
baseUrl += "&appid="+str(apiid)
# make get requetss using requests module
r = requests.get(baseUrl)
# return the response
return r

# show data in human readabale format

def display(resp):
# this means request was successfull
if resp.status_code == 200:
data = resp.json()
print(f"""{data['name']} Weather Forecast:
Type: {data['weather'][0]['description']}
Wind Speed : {data['wind']['speed']} miles/hr
Visibility : {data['visibility']} m
Min. Temp : {data['main']['temp_min']} F
Max Temp : {data['main']['temp_max']} F
""")
else:
print("Request Failed, Error : ", resp.status_code)

def main():
while True:
# ask the user for his/her choice
choice = int(
input("How do you want to search ? :\n1. By Zip Code\n2. By City Name\n3. Exit\n"))

if choice == 1:
# ask for zip code
try:
# ask for zip code
zCode = int(input("Enter zip code : "))
# fetch data from website
resp = get_web_data(zCode, None)
display(resp)
except Exception as ex:
print("Error : ", ex)
elif choice == 2:
try:
cname = input("Enter city name : ")
# mak call to fetch fetch_data
resp = get_web_data(None, cname)
display(resp)
except Exception as ex:
print("Error : ", ex)
elif choice == 3:
break
else:
print("Invalid Choice..\n")

if __name__ == "__main__":
main()
