Implementing comparison operators via 'tuple' and 'tie', a good idea?
(Note: tuple and tie can be taken from Boost or C++11.)
When writing small structs with only two elements, I sometimes tend to choose a std::pair , as all important stuff is already done for that datatype, like operator< for strict-weak-ordering.
The downsides though are the pretty much us...
Sort a list by multiple attributes?
...
A key can be a function that returns a tuple:
s = sorted(s, key = lambda x: (x[1], x[2]))
Or you can achieve the same using itemgetter (which is faster and avoids a Python function call):
import operator
s = sorted(s, key = operator.itemgetter(1, 2))
And notice that here...

Why does pattern matching in Scala not work with variables?
...
What you're looking for is a stable identifier. In Scala, these must either start with an uppercase letter, or be surrounded by backticks.
Both of these would be solutions to your problem:
def mMatch(s: String) = {
val target: String = "a"
...
data type not understood
...ix = np.zeros((nrows, ncols))
Since the shape parameter has to be an int or sequence of ints

Otherwise you are passing ncols to np.zeros as the dtype.
