python（7）- 小程式練習：迴圈語句for，while實現99乘法表

列印99乘法表

for 迴圈語句實現：

1 for i in range(1,10):2     for j in range(1,10):3         print(j,"x",i,"=",i*j,"\t",end="")   #因為print自動換行，end="" 為結尾不換行4         if i==j:5             print("")  #此處是結尾換行6             break

 

 while迴圈語句實現：

 1 i=0 2 j=0 3 while i <9: 4     i+=1 5     while j <9: 6         j += 1 7         print(j, "x", i, "=", i * j, "\t", end="") 8         if i==j: 9             print("")10             j=011             break

輸出結果：

1 1 x 1 = 1  2 1 x 2 = 2   2 x 2 = 4  3 1 x 3 = 3   2 x 3 = 6   3 x 3 = 9  4 1 x 4 = 4   2 x 4 = 8   3 x 4 = 12  4 x 4 = 16 5 1 x 5 = 5   2 x 5 = 10  3 x 5 = 15  4 x 5 = 20  5 x 5 = 25 6 1 x 6 = 6   2 x 6 = 12  3 x 6 = 18  4 x 6 = 24  5 x 6 = 30  6 x 6 = 36 7 1 x 7 = 7   2 x 7 = 14  3 x 7 = 21  4 x 7 = 28  5 x 7 = 35  6 x 7 = 42  7 x 7 = 49 8 1 x 8 = 8   2 x 8 = 16  3 x 8 = 24  4 x 8 = 32  5 x 8 = 40  6 x 8 = 48  7 x 8 = 56  8 x 8 = 64 9 1 x 9 = 9   2 x 9 = 18  3 x 9 = 27  4 x 9 = 36  5 x 9 = 45  6 x 9 = 54  7 x 9 = 63  8 x 9 = 72  9 x 9 = 81
