class method generates “TypeError: … got multiple values for keyword argument …”
...de:

a thong is something
<__main__.foo object at 0x321c290>
You can see that 'thing' has been assigned a reference to the instance 'myfoo' of the class 'foo'. This section of the docs...
Asserting successive calls to a mock method
Mock has a helpful assert_called_with() method . However, as far as I understand this only checks the last call to a method.
If I have code that calls the mocked method 3 times successively, each time with different parameters, how can I assert these 3 calls with their specific parameters?

Calculating a directory's size using Python?
...
This walks all sub-directories; summing file sizes:
import os
def get_size(start_path = '.'):
total_size = 0
for dirpath, dirnames, filenames in os.walk(start_path):
for f in filenames:
fp = os.path.join(dirpath, f)
# skip if it is symbolic link

How do you query for “is not null” in Mongo?
...
db.collection_name.find({"filed_name":{$exists:true}});
fetch documents that contain this filed_name even it is null.
My proposition:
db.collection_name.find({"field_name":{$type:2}}) //type:2 == String
You can check on the required...
What is a plain English explanation of “Big O” notation?
...
-1: This is blatantly wrong: _"BigOh is relative representation of complexity of algorithm". No. BigOh is an asymptotic upper bound and exists quite well independent of computer science. O(n) is linear. No, you are confusing BigOh with theta. log n is O(...
Number of elements in a javascript object
...et it.
In the past, Mozilla's Javascript variant exposed the non-standard __count__, but it has been removed with version 1.8.5.
For cross-browser scripting you're stuck with explicitly iterating over the properties and checking hasOwnProperty():
function countProperties(obj) {
var count = 0;...

phpcms v9类别调用方法 - 更多技术 - 清泛网 - 专注C/C++及内核技术
...前面加一句把类别缓存加载进来：
<?php $TYPE = getcache('type_content','commons');?>
然后在循环里写：
<a href="index.php?m=content&c=type&catid={$catid}&typeid={$r[typeid]}">{$TYPE[$r[typeid]][name]}</a>
这样就可以调用出来类别了，不过链接暂时无效，因...
