小编mit*_*h36的帖子

我用:

• DjangoCMS 2.4
• Django 1.5.1
• Python 2.7.3

我想检查我的占位符是否为空.

<div>
    {% placeholder "my_placeholder" or %}
    {% endplaceholder %}
</div>

如果占位符为空,我不希望创建占位符之间的html.

{% if placeholder "my_placeholder" %}
<div>
    {% placeholder "my_placeholder" or %}
    {% endplaceholder %}
</div>
{% endif %}

我无法在xmlrpclib.ServerProxy()上获得方法列表.我尝试过使用dir(); 但是,解释器会一直返回错误.

这是我试过的:

>>>s = xmlrpclib.ServerProxy("http://192.168.1.72:8888")
>>>dir(s)

我收到这个错误:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/xmlrpclib.py", line 1224, in __call__

不支持Dir(),如何获取方法列表？

我在目录中有两个文件,它们都是.txt文件,每行有一个单词,用于多行.我需要将它们合并,然后将新文件按字母顺序排列.

我在PHP中完成了这个,但是我怎么能在Python 2.7中做到这一点？

<?php
$files = glob("./files/*.??");
$out = fopen("listTogether.txt", "w");
foreach($files as $file){
    fwrite($out, file_get_contents($file));
}
fclose($out);
?>
