Python使用for loop迴圈印出九九乘法表。
for i in range(1, 10):
for j in range(1, 10):
print(str(i) + 'x' + str(j) + '=' + str(i * j) + ' ', end='')
print() # newline
1x1=1 1x2=2 1x3=3 1x4=4 1x5=5 1x6=6 1x7=7 1x8=8 1x9=9
2x1=2 2x2=4 2x3=6 2x4=8 2x5=10 2x6=12 2x7=14 2x8=16 2x9=18
3x1=3 3x2=6 3x3=9 3x4=12 3x5=15 3x6=18 3x7=21 3x8=24 3x9=27

7x1=7 7x2=14 7x3=21 7x4=28 7x5=35 7x6=42 7x7=49 7x8=56 7x9=63
8x1=8 8x2=16 8x3=24 8x4=32 8x5=40 8x6=48 8x7=56 8x8=64 8x9=72
9x1=9 9x2=18 9x3=27 9x4=36 9x5=45 9x6=54 9x7=63 9x8=72 9x9=81
使用Python舊式的字串格式化印出。

for j in range(1, 10):
print('%dx%d=%2d ' % (i, j, i * j), end='')
print() # newline

使用Python 新的f-string字串格式化印出。
for i in range(1, 10):
for j in range(1, 10):
print(f'{i}x{j}={i * j:2} ', end='')
print() # newline
1x1= 1 1x2= 2 1x3= 3 1x4= 4 1x5= 5 1x6= 6 1x7= 7 1x8= 8 1x9= 9
