如何用python打印九九乘法表

可以使用嵌套循环来打印九九乘法表，例如以下代码：

for i in range(1, 10):    for j in range(1, i+1):        print(f"{j} x {i} = {i*j}", end="\t")    print()

输出结果为：

1 x 1 = 11 x 2 = 22 x 2 = 41 x 3 = 32 x 3 = 63 x 3 = 91 x 4 = 42 x 4 = 83 x 4 = 124 x 4 = 161 x 5 = 52 x 5 = 103 x 5 = 154 x 5 = 205 x 5 = 251 x 6 = 62 x 6 = 123 x 6 = 184 x 6 = 245 x 6 = 306 x 6 = 361 x 7 = 72 x 7 = 143 x 7 = 214 x 7 = 285 x 7 = 356 x 7 = 427 x 7 = 491 x 8 = 82 x 8 = 163 x 8 = 244 x 8 = 325 x 8 = 406 x 8 = 487 x 8 = 568 x 8 = 641 x 9 = 92 x 9 = 183 x 9 = 274 x 9 = 365 x 9 = 456 x 9 = 547 x 9 = 638 x 9 = 729 x 9 = 81

每一行的表达式用制表符(\t)隔开，使用print()函数的默认参数end="\n"来换行。
