Python 字符串换行的多种方式

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
