Python 打印九九乘法表（正三角格式输出）

# 循环从1到10，不包含10，即1 2 3 4 5 6 7 8 9
for i in range (1,10):
    # 第一个乘数从1开始到9
    for j in range(1,i+1):
        # 之所以将j放到前面是为了乘法表输出乘法表的可读性(第一个乘数是较小的数)，end="" 每输出一个程式后添加的空格
        print(j,"*",i,"=",j*i,"\\t",end="")
        # 打印完每一行后换行，即相等的两个数乘积完后换行
        if i == j:
            print()

# 打印结果：
1 * 1 = 1 	
1 * 2 = 2 	2 * 2 = 4 	
1 * 3 = 3 	2 * 3 = 6 	3 * 3 = 9
