# 九九乘法表第二种方法
first = 1
while first <= 9:
    sec = 1
    while sec <= first:
        print(str(sec)+"*"+str(first)+"="+str(sec * first), end="\t")
        sec += 1
    print()
    first += 1

# 将九九乘法表倒过来
first1 = 9
while first1 > 0:
    sec1 = 1
    while sec1 <= first1:
        print(str(sec1)+"*"+str(first1)+"="+str(sec1 * first1), end="\t")
        sec1 += 1
    print()
    first1 -= 1

# 输出一个直角三解形，用户指定输出行数, 可以考虑把三角形倒过来
line = 1
while line <=5:
    lin1 = line
    while lin1 > 0:
        print("*", end="")
        lin1 -= 1
    print()
    line += 1

# 将直角三角形倒过来
line2 = 5
while line2 > 0:
    line3 = line2
    while line3 > 0:
        print("*", end="")
        line3 -= 1
    print()
    line2 -= 1
