各位大哥帮帮忙，python三进制的一些问题
题目有点长……我分开发# Prompts(提示) the user for two integers. #how to define these two integers?
# - The first one should be between 1 and 4, with#first for direction
# * 1 meaning initially looking North, 北
# * 2 meaning initially looking East,东
# * 3 meaning initially looking South, 南
# * 4 meaning initially looking West.西
# - The second one should be positive. When written in base 3, its consecutive连贯的#what's base 3?
# digits read from left to right represent the directions to take, with
# * 0 meaning going in the direction one is initially looking at,
# * 1 meaning 45 degrees left of the direction one is initially looking at,
# * 2 meaning 45 degrees right of the direction one is initially looking at.#3nary
#
# Prints out:
# - the direction one is originally looking at, as an arrow,
# - the representation of the second digit in base 3,
# - the corresponding sequence of directions to take, as arrows,
# - in case one is originally(最初) looking North or South, the path,
# so the sequence（数列） of arrows again, but nicely displayed.
import sys
try:
initial_direction, directions = input('Enter an integer between 1 and 4 '
'and a positive integer: '
).split()
if len(initial_direction) != 1\
or len(directions) > 1 and directions == '0':
raise ValueError
initial_direction = int(initial_direction)
directions = int(directions)
if initial_direction not in {1, 2, 3, 4} or directions < 0:
raise ValueError
except ValueError:
print('Incorrect input, giving up.')
sys.exit()
