第一种：

x0 = '<?xml version="1.0"?>' \ '<ol>' \ ' <li><a href="/python" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Python</a></li>' \ ' <li><a href="/ruby" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Ruby</a></li>' \ '</ol>'

第二种：

x1 = '<?xml version="1.0"?> \<ol> \ <li><a href="/python" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Python</a></li> \ <li><a href="/ruby" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Ruby</a></li> \</ol>'

第三种：

x2 = ('<?xml version="1.0"?>' '<ol>' ' <li><a href="/python" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Python</a></li>' ' <li><a href="/ruby" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Ruby</a></li>' '</ol>')

第四种：

x3 = '''<?xml version="1.0"?><ol> <li><a href="/python" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Python</a></li> <li><a href="/ruby" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Ruby</a></li></ol>'''

下面看下python代码过长的换行

python代码换行就是每行后面加个 \

举个栗子：

time = "2017" print "one" + "," \ + "two" \ + ",three" + \ "," + time

打印出来就是：

one,two,three,2017

再举一个栗子：

print "this line is toooooooooooo \ long"

打印出来：

this line is toooooooooooo long
