input: Write a python function to create a list of HealthData objects from given lists of months, calories, and minutes.
  assert len(create_health_data(["January", "February"], [2200, 2100], [1200, 1100])) == 2
  assert create_health_data(["March"], [2000], [1000])[0].month == "March"
  assert create_health_data(["April"], [1800], [900])[0].calories == 1800
output: def create_health_data(months, calories, minutes):
