用for循环打出倒版的99乘法表

99= 81 98= 72 88= 64 97= 63 87= 56 77= 49 96= 54 86= 48 76= 42 66= 36 95= 45 85= 40 75= 35 65= 30 55= 25 94= 36 84= 32 74= 28 64= 24 54= 20 44= 16 93= 27 83= 24 73= 21 63= 18 53= 15 43= 12 33= 9 92= 18 82= 16 72= 14 62= 12 52= 10 42= 8 32= 6 22= 4 91= 9 81= 8 71= 7 61= 6 51= 5 41= 4 31= 3 21= 2 1*1= 1

代码如下：

for i in range(9,0,-1): for j in range(i,0,-1): print(j,"",i,"=",ij,end=" ") print()
