Question

I need to write a Python Program for the following question.

Link for tallest mountains: https://en.wikipedia.org/wiki/List_of_mountains_by_elevation

Use top 10 tallest mountains.

Part One

• Wikipedia has a list of the tallest mountains in the world each mountain's elevation. Pick 10 mountains from this list.
  • Create a dictionary with the mountain names as keys, and the elevations as values.
  • Print out just the mountains' names, by looping through the keys of your dictionary.
  • Print out just the mountains' elevations, by looping through the values of your dictionary.
  • Print out a series of statements telling how tall each mountain is: "Everest is 8848 meters tall."

Part Two

• Revise your final output from Mountain Heights, so that the information is listed in alphabetical order by each mountain's name.
  • That is, print out a series of statements telling how tall each mountain is: "Everest is 8848 meters tall."
  • Make sure your output is in alphabetical order.

Part Three

• This is an extension of Mountain Heights. Make sure you save this program under a different filename, such as mountain_heights_3.py, so that you can go back to your original program if you need to.
  • The list of tallest mountains in the world provided all elevations in meters. Convert each of these elevations to feet, given that a meter is approximately 3.28 feet. Make sure you use a function to do this conversion
  • Create a new dictionary, where the keys of the dictionary are still the mountains' names. This time however, the values of the dictionary should be a list of each mountain's elevation in meters, and then in feet: {'everest': [8848, 29029]}
  • Print out just the mountains' names, by looping through the keys of your dictionary.
  • Print out just the mountains' elevations in meters, by looping through the values of your dictionary and pulling out the first number from each list.
  • Print out just the mountains' elevations in feet, by looping through the values of your dictionary and pulling out the second number from each list.
  • Print out a series of statements telling how tall each mountain is: "Everest is 8848 meters tall, or 29029 feet."
