A simple CLI and python wrapper for the Open-Notify API. This CLI returns the current position of the ISS along with information about current astronauts and their spacecrafts.
Clone this git repo and run cli.py from the command line.
Available commands:
loc: Get the current coordinates for the ISSpeople: Get the names of people currently in space, along with the spacecraft they are on.- '-h': View help
Implement a Python script that will accept the following command-line arguments, along with any required information, and print the expected results. Please also use python data-classes to create a python native interface for the responses from the api.
loc
print the current location of the ISS
Example: “The ISS current location at {time} is {LAT, LONG}”
people
for each craft print the details of those people that are currently in space
Example: “There are {number} people aboard the {craft}. They are {name[0]}…{name[n]}”
Sometimes the open-notify API will have some endpoints that are not available due to load, your application should be able to handle this case and you can use some mock data to show how it would work
For location the following would be some mock data from the api:
{“message”: “success”, “timestamp”: 123456789, “iss_position”: {“longitude”: “-10.1234”, “latitude”: “31.41592”}}
For the current crew on the iss, an example might be:
{“message”: “success”, “number”: 4, “people”: [{“name”: “James Tiberius Kirk”, “craft”: “NCC-1701”}, {“name”: “Chris Hadfield”, “craft”: “ISS”}, {“craft”: “NCC-1701”, “name”: “S’chn T’gai Spock”}, {“name”: “Hikaru Kato Sulu”}]}
These are question I would have asked during the design phase to clarify ambiguous requirements.
-
"Implement a Python script that will accept the following command-line arguments":
- Does this CLI need to accept multiple arguments at one or just one at a time? I opted to design the CLI to only accept a single argument at a time in order to simplify the output. It is easier to parse a single result and run the application a second time than to assume the consumer will have the ability to parse multiple results.
Processing multiple args at a time would be a good use case for async requests or at least an interesting exercise.
-
"...along with any required information..."
- This prompt asked for the ability to submit required information, but no other information is required to fulfill the design requirements. The ability to supply & process flags could be easily added with argeparse and the existing router.
