# 4.18:  Extending the previous code, use a single call to .rstrip() to remove any punctuation.
# (Hint:  you can place any punctuation characters to be removed together in a single string
# argument to rstrip(); any single character within the string will be removed.)

# Expected Output:

# I
# could
# I
# wouldn't
# I
# might
# Might
# I
