python3.x的print（）函数默

初学python ，写了个99乘法表，

for i in range(1, 10) :

for j in range(1, i+1) :

print(j, 'x', i, '=', j*i,,end='t')

print('n')

这里end='t'表示以TAB结尾

开始并不知道加end参数，所以每次输出完一行就自动换行再输出第二行

>>> help(print)

Help on built-in function print in module builtins:

print(…)

print(value, …, sep=' ', end='n', file=sys.stdout, flush=False)

Prints the values to a stream, or to sys.stdout by default.

Optional keyword arguments:

file: a file-like object (stream); defaults to the current sys.stdout.

sep: string inserted between values, default a space.

end: string appended after the last value, default a newline.

flush: whether to forcibly flush the stream.

sep表示值与值之间默认以空格相隔开，end表示结尾默认换行

另外在python2.X中，只需要在print后面添加逗号就可以
