Python3.X实现不换行打印

python3中print函数中的参数end默认值为’\n’，表示换行，改变end的赋值，就不会换行了，例如打印个99乘法表：

for i in range(1, 10):
    print()
    for j in range(1, i+1):
        print ("%d*%d=%d," % (i, j, i*j),end=' ')

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