Scoping in Python 'for' loops
... understand generally how scoping works in Python for loops. My question is why the design decisions were made in this way. For example (no pun intended):

Repeat Character N Times
...
These days, the repeat string method is implemented almost everywhere. (It is not in Internet Explorer.) So unless you need to support older browsers, you can simply write:

Check whether an array is empty [duplicate]

$errors = array_filter($errors);
if (!empty($errors)) {
}
array_filter() function's default behavior will remove all values from ...

In general, you would see two branch types:

Entity Framework vs LINQ to SQL
...# 3.0 and .Net Framework 3.5.
LINQ to Entities (ADO.Net Entity Framework) is an ORM (Object Relational Mapper) API which allows for a broad definition of object domain models and their relationships to many different ADO.Net data providers. As such, you can mix and match a number of different data...
Appending a vector to a vector [duplicate]

a.insert(std::end(a), std::begin(b), std::end(b));
The second variant is a more generically applicable solution, as b could also be an array. However, it requires C++11. If you want to work with user-defined types, use ADL:
using std::begin, std::end;
a.insert(end(a), begin(b), end(b));

Create a branch called mvn-repo to host your maven artifacts.
Use the github site-maven-plugin to push your artifacts to github.
Configure maven to use your remote mvn-repo as a maven repository.

Difference in months between two dates

Assuming the day of the month is irrelevant (i.e. the diff between 2011.1.1 and 2010.12.31 is 1), with date1 > date2 giving a positive value and date2 > date1 a negative value
