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
