可以使用两个嵌套的for循环来打印九九乘法表。具体代码如下：
for i in range(1, 10):for j in range(1, i+1):
print(f"{j} {i} = {ij}“, end=”\t")
print()
运行上述代码，即可打印出九九乘法表：
1 1 = 1 1 2 = 22 2 = 4 1 3 = 32 3 = 63 3 = 9 1 4 = 42 4 = 83 4 = 124 4 = 16 1 5 = 52 5 = 103 5 = 154 5 = 205 5 = 25 1 6 = 62 6 = 123 6 = 184 6 = 245 6 = 306 6 = 36 1 7 = 72 7 = 143 7 = 214 7 = 285 7 = 356 7 = 427 7 = 49 1 8 = 82 8 = 163 8 = 244 8 = 325 8 = 406 8 = 487 8 = 568 8 = 64 1 9 = 92 9 = 183 9 = 274 9 = 365 9 = 456 9 = 547 9 = 638 9 = 729 * 9 = 81
