"""
MovieGuide.py

This program allows each theater patron to enter a value from
0 to 4 indicating the number of stars that the patron awards
to the Guide's featured movie of the week. The program
executes continuously until the theater manager enters a
negative number to quit. At the end of the program, the
average star rating for the movie is displayed.
"""

# Initialize variables.
totalStars = 0 # total of star ratings.
numPatrons = 0 # keep track of number of patrons
averageStars = 0

# Get input.
numStarsString = input("Enter rating for featured movie: ")

# Convert to double.
numStars = float(numStarsString)

# Write while loop here
while numStars >= 0 and numStars <= 4:
numPatrons = numPatrons + 1 # incrementor
totalStars = totalStars + numStars
# Get input.

# Convert to double.
numStars = float(numStarsString)
