Baseball players' height

You are a huge baseball fan. You decide to call the MLB (Major League Baseball) and ask around for some more statistics on the height of the main players. They pass along data on more than a thousand players, which is stored as a regular Python list: height_in. The height is expressed in inches. Can you make a numpy array out of it and convert the units to meters?

height_in is already available and the numpy package is loaded, so you can start straight away (Source: stat.ucla.edu).

Exercise instructions

  • Create a numpy array from height_in. Name this new array np_height_in.
  • Print np_height_in.
  • Multiply np_height_in with 0.0254 to convert all height measurements from inches to meters. Store the new values in a new array, np_height_m.
  • Print out np_height_m and check if the output makes sense.
