Python： 使print函数输出时不要换行

            

比如要打印一个乘法表

for i in range(1,10):
    for j in range(1,i+1):
        print j,"*",i,"=",i*j," "
    print "\n"


输出如下：

1 * 1 = 1  

1 * 2 = 2  
2 * 2 = 4  

。。。。

可以看到输出一行就会自动换行。稍微修改一下在print输出后面加一个逗号便不会换行 如下：

for i in range(1,10):
    for j in range(1,i+1):
        print j,"*",i,"=",i*j," ", #加一个逗号
    print "\n"

输出如下：

1 * 1 = 1   

1 * 2 = 2   2 * 2 = 4   

1 * 3 = 3   2 * 3 = 6   3 * 3 = 9   

1 * 4 = 4   2 * 4 = 8   3 * 4 = 12   4 * 4 = 16   

1 * 5 = 5   2 * 5 = 10   3 * 5 = 15   4 * 5 = 20   5 * 5 = 25   

1 * 6 = 6   2 * 6 = 12   3 * 6 = 18   4 * 6 = 24   5 * 6 = 30   6 * 6 = 36   

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

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

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