关于#Python#的问题，如何解决？

Question

三是求单词的长度并排序，四是求曼哈顿距离，尽量简易易懂，且第四题尽量使用for循环，大概就是这样了

Answer 1

//3.输入多个以逗号分隔的单词，按字母顺序排序
words = input().split(',')
words.sort()
print(words)

//4.
p1 = list(eval(input('enter the coordinates of the first point (separated by commas):')))
p2 = list(eval(input('enter the coordinates of the second point (separated by commas):')))
s = 0
for i in range(0,len(p1)):
    s = s + abs(p1[i]-p2[i])

print(s)
