# Compute the median of a collection of values entered by the user

# Create an empty list to hold the values entered by the user
data = []

# Read the first input value
value = input("Enter a value (blank line to quit): ")

# while the value entered by the user is not a blank line
while value != "":
  # append the value entered by the user to the end of the list
  data.append(float(value))

  # read the next input value from the user
  value = input("Enter a value (blank line to quit): ")

# Sort the list
data.sort()

# If the length of the list is 0
if len(data) == 0:
  # Report that there is no median
  print("That list isn't long enough to have a median value.")
# elif the length of the list is odd
elif len(data) % 2 == 1:
  # Report that the median is the middle value in the list
  print("The median value of that list is", data[len(data) // 2])
# Otherwise
else:
  # Report that the median is the average of the two middle values in the list
  print("The median value of that list is", \
        (data[len(data) // 2] + data[len(data) // 2 - 1]) / 2)
