My Answer：

def get_DoorMat1(l, h):
    symbol = '.|.'
    for i in range(l / 2):
        print ((2 * i + 1) * symbol).center(3 * l, '-')

    print 'WELCOME'.center(3 * l, '-')

    for i in range(l / 2):
        print ((2 * (l / 2 - (i + 1)) + 1) * symbol).center(3 * l, '-')

def get_DoorMat(l, h):   ##最優解
    symbol = '.|.'
    pattern = [(symbol*(2*i + 1)).center(h, '-') for i  in range(l/2)]
    print('\n'.join(pattern + ['WELCOME'.center(h, '-')] + pattern[::-1]))


if __name__=='__main__':
    l, h = map(int, raw_input().split())
    DoorMat = get_DoorMat(l, h)
