python的学校的题目好难的

a = input()
input_str = a.split()
res_type = int(input_str[0])
row = int(input_str[1])


if res_type == 1:
    col = int(input_str[2])
    for i in range(row):
        print("*" * col)


if res_type == 2:
    for i in range(row):
        i = (i+1)
        _str = ("A" * i).rjust(row) + " " + ("A" * i).ljust(row)
        print(_str)

if res_type == 3:
    flag = "A"
    for i in range(row, 0, -1):
        if flag == "B":
            print((("B"*(i-1)) + "B" + ("B"*(i-1))).center(row*2))
            flag = "A"
        else:
            print((("A"*(i-1))+ "A" + ("A"*(i-1))).center(row*2))
            flag = "B"
