... actually derived from __init__.py. It does not change the value of a that foobar sees because foobar lives in the actual file bar.py. You could set bar.bar.a if you wanted to change that.
This is one of the dangers of using the from foo import bar form of the import statement: it splits bar into t...
Difference between / and /* in servlet mapping url pattern
...ill be selected only after servlet mappings which are exact matches (like /foo/bar) and those which are path mappings longer than /* (like /foo/*). Note that the empty string mapping is an exact match for the context root (http://host:port/context/).

What is the difference between URI, URL and URN? [duplicate]

file:///home/user/file.txt
http://example.com/resource?foo=bar#fragment
/other/link.html (A relative URL, only useful in the context of another URL)

Relationship between SciPy and NumPy
...s in its own namespace. In other words, if there's a function named numpy.foo , there's almost certainly a scipy.foo . Most of the time, the two appear to be exactly the same, oftentimes even pointing to the same function object.

...of boost::variant<A, B, C, D, ...> instead. Like if you have a class Foo, Bar and Baz, it looks like this:

template<typename T> variant_type createInstance() {
return variant_type(T());
}
typedef std::map<std::string, v...

How dangerous is it to access an array out of bounds?
...sting is that hyper-modern compilers may decide that if code tries to read foo[0] through foo[len-1] after having previously used a check of len against the array length to either execute or skip a piece of code, the compiler should feel free to run that other code unconditionally even if the applic...
How does the Java 'for each' loop work?
