For this assignment, you will need to be able to read data from the Open Weather Map data source. They have an Application Programming Interface (API) available to developers to access this data. You will need to sign up on the website as a developer.

• https://openweathermap.org/api
• Sign up for the Current weather data service
• You will get a developer key which is a 32 digit hexadecimal number
• This key will be used in your project.

When you read info from the OpenWeather API, it comes as a JSON data stream. I have created an intermediate API for you to more easily get specific weather values from this JSON data. The various functions are described below along with an example of how they would work in your WeatherApp.py program.

Use this function to set your private API key for OpenWeather

WeatherInfo.setKey("1234567890abcdef")

Once your key is set, this will make the call to the OpenWeather database for a live weather update. This must be done before any of the other calls will return accurate weather information. This function will return a boolean value to indicate if the call was successful. For example, if the defined city is not valid or misspelled, the function will get an error from the OpenWeather API. In this case, the function would return False to indicate that the call was not successful. If the weather data is successfully updated, the function will return True

success = WeatherInfo.updateWeather()

if(success == True):
  print("It worked")
else:
  print("Invalid City")

This function will return a string value that is the current weather description. Example descriptions:

• light clouds
• heavy rain
• sunny

print(WeatherInfo.getDescription())
description = WeatherInfo.getDescription()

Returns a float of the current temperature. The unit of this temperature is Kelvin.

print(WeatherInfo.getTemp())
temp = WeatherInfo.getTemp()

Returns a float of the current "feels like" temperature in Kelvin. Feels like is a unit that combines the air temp, wind speed, and humidity to give an adjusted temperature to what it would feel like outside.

print(WeatherInfo.getFeelsLike())
feelTemp = WeatherInfo.getFeelsLike()

Returns an integer value in the range (0-100) on how humid it is currently.

print(WeatherInfo.getHumidity())
humidity = WeatherInfo.getHumidity()

Returns an integer value for the barometric pressure.

print(WeatherInfo.getPressure())
pressure = WeatherInfo.getPressure()

Returns a float value for the current wind speed measured in meters per second.

print(WeatherInfo.getWindSpeed())
speed = WeatherInfo.getWindSpeed()

• Ask the user for their city.
  • If the user leaves it blank, assume that they want the weather data for Omaha.
• Report the current weather for the user selected city.
• Ask the user if they would like to get the weather report for another city.
  • This should be answered in a clear way defined in the program.
  • In other words, let the user know how they should respond to your question as part of the question.
• Repeat the process as many times as the user continues.

• Provide an intro so the user knows what city this info is for.
• Provide the following information:
  • Weather Description
  • Temperature (in Fahrenheit) as a whole number
  • Humidity
  • Wind Speed and wind Beaufort description
  • What I should wear today (see below)

To make this app more useful, we want to give advice on what the user should wear based on the current weather conditions.

Based on the feels like temperature the user should wear:

• light jacket (55 - 65 Fahrenheit)
• medium jacket (40 - 54 Fahrenheit)
• heavy coat (below 40 Fahrenheit)

The user should bring an umbrella if it is raining. This info will be found in the description. Rain Types:

• mist
• light rain
• rain
• heavy rain

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.Wikipedia (Note: Our program provide wind speed in Meters per Second.)

• Calm (<1 mph)
• Light air (1-3 mph)
• Light breeze (4-7 mph)
• Gentle breeze (8-12 mph)
• Moderate breeze (13-18 mph)
• Fresh breeze (19-24 mph)
• Strong breeze (25-31 mph)
• High wind (32-38 mph)
• Gale (39-46 mph)
• Strong gale (47-54 mph)
• Storm (55-63 mph)
• Violent storm (64-72 mph)
• Hurricane (>= 73 mph)

Enter city: Omaha
The current weather in Omaha is broken clouds with 87% humidity.
Temperature: 35 degrees Fahrenheit
Wind speed: 2.12 mph - Light air
You should wear a heavy coat today.

Would you like another weather report (Y/N): Y

Enter city: Orlando
The current weather in Orlando is clear sky with 67% humidity.
Temperature: 59 degrees Fahrenheit
Wind speed: 3.8 mph - Light breeze
You should wear a light jacket today.

Would you like another weather report (Y/N): N

Have a nice day.
