input: Write a function that prints the information of a city including its name, country, latitude, and continent. The function should be able to accept these details as parameters and format them into a readable string. Provide assert statements to test the function, ensuring that the output matches the expected formatted string for each city. The function should return None and rely on print statements for output.
  
  def get_city_info(city, country, latitude, continent):
      print("City: {}, Country: {}, Latitude: {}, Continent: {}".format(city, country, latitude, continent))
  
  assert get_city_info('Edinburgh', 'Scotland', '54.6°N', 'UK') is None
  assert get_city_info('Paris', 'France', '48.86°N', 'Europe') is None
  assert get_city_info('Dhaka', 'Bangladesh', '23.78°N', 'Asia') is None
output: def get_city_info(city, country, latitude, continent):
      print("City: {}, Country: {}, Latitude: {}, Continent: {}".format(city, country, latitude, continent))
