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
