二、代码
#!/usr/bin/env python
# coding: utf-8N, M = map(int, input().split())
# N, M = 9, 27
str1 = '-'
str2 = '.|.'
str3 = 'WELCOME'
for i in range(N // 2):# print((str1 * ((M + 3) // 2 - (3 * (i + 1)))) + (str2 * (i * 2 + 1)) + (str1 * ((M + 3) // 2 - (3 * (i + 1)))))print((str2 * (i * 2 + 1)).center(M, str1))print(str3.center(M, str1))for i in range(N // 2):a = (i + 1) * 2#b = (M + 3) // 2# print(str1 * (b - ((N - a + 1) // 2 * 3)) + str2 * (N - a) + str1 * (b - ((N - a + 1) // 2 * 3)))print((str2 * (N - a)).center(M, str1))
