What are the differences between Generics in C# and Java… and Templates in C++? [closed]
... my voice to the noise and take a stab at making things clear:
C# Generics allow you to declare something like this.
List<Person> foo = new List<Person>();
and then the compiler will prevent you from putting things that aren't Person into the list.
Behind the scenes the C# compiler is j...
Method Resolution Order (MRO) in new-style classes?
...ject'>)
with A forced to come in resolution order only once and after all of its subclasses, so that overrides (i.e., C's override of member x) actually work sensibly.
It's one of the reasons that old-style classes should be avoided: multiple inheritance with "diamond-like" patterns just doesn...
Character reading from file in Python
... print repr(line)
It's also possible to open files in update mode, allowing both reading and writing:
with codecs.open('test', encoding='utf-8', mode='w+') as f:
f.write(u'\u4500 blah blah blah\n')
f.seek(0)
print repr(f.readline()[:1])

mu, sigma = 100, 15
x = mu + sigma * np.random.randn(10000)
bins = [0, 40, 60, 75, 90, 110, 125, 140, 160, 200]

Find() vs. Where().FirstOrDefault()
...thods. Find is available only for the List<T>. Methods that are generally more applicable, are then more reusable and have a greater impact.
I guess my next question would be why did they add the find at all. That is a good tip. The only thing I can think of is that the FirstOrDefault coul...
Type erasure techniques
(With type erasure, I mean hiding some or all of the type information regarding a class, somewhat like Boost.Any.)
I want to get a hold of type erasure techniques, while also sharing those, which I know of. My hope is kinda to find some crazy technique that somebody thought of in his/her darkest h...
In c# what does 'where T : class' mean?

import os
import sys
sys.path.insert(0, os.getcwd())
