九九乘法表python代码倒三角

以下是九九乘法表python代码倒三角:

for i in range(9, 0, -1):
    for j in range(i, 0, -1):
        print(f"{j}x{i}={i*j}", end="\t")
    print()

输出结果:

9x9=81  8x9=72  7x9=63  6x9=54  5x9=45  4x9=36  3x9=27  2x9=18  1x9=9   
8x8=64  7x8=56  6x8=48  5x8=40  4x8=32  3x8=24  2x8=16  1x8=8   
7x7=49  6x7=42  5x7=35  4x7=28  3x7=21  2x7=14  1x7=7   
6x6=36  5x6=30  4x6=24  3x6=18  2x6=12  1x6=6   
5x5=25  4x5=20  3x5=15  2x5=10  1x5=5   
4x4=16  3x4=12  2x4=8   1x4=4   
3x3=9   2x3=6   1x3=3   
2x2=4   1x2=2   
1x1=1   

以下是完整的九九乘法表python代码,包括正三角和倒三角:

正三角:

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

倒三角:

for i in range(9, 0, -1):
    for j in range(i, 0, -1):
        print(f"{j}x{i}={i*j}", end="\t")
    print()

输出结果:

正三角:

1x1=1   
1x2=2   2x2=4   
1x3=3   2x3=6   3x3=9   
1x4=4   2x4=8   3x4=12  4x4=16  
1x5=5   2x5=10  3x5=15  4x5=20  5x5=25  
1x6=6   2x6=12  3x6=18  4x6=24  5x6=30  6x6=36
