python打印九九乘法表

지난달

幼儿园把进位加法,退位减法都教了,试着让小宝贝了解一下乘法。
先用Python打印一张九九乘法表:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

for i in range(1,10):
    for j in range(1,i+1):
        print('{1}X{0}={2}'.format(i,j,i*j),end='\t')
    print('\n')

E:>python 九九乘法表.py
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

1X7=7 2X7=14 3X7=21 4X7=28 5X7=35 6X7=42 7X7=49

1X8=8 2X8=16 3X8=24 4X8=32 5X8=40 6X8=48 7X8=56 8X8=64

1X9=9 2X9=18 3X9=27 4X9=36 5X9=45 6X9=54 7X9=63 8X9=72 9X9=81
