Mockito match any class argument
...
There is another way to do that without cast:
when(a.method(Matchers.<Class<A>>any())).thenReturn(b);
This solution forces the method any() to return Class<A> type and not its default value (Object).

What is the result of % in Python?
...erator, so watch out if you are coming from a language with automatic type casting (like PHP or JS) where an expression like '12' % 2 + 3 is legal: in Python it will result in TypeError: not all arguments converted during string formatting which probably will be pretty confusing for you.

Macro vs Function in C
...ch as checking their type, sizeof, check struct members are present before casting(can be useful for polymorphic types).Or check an array meets some length condition.see: https://stackoverflow.com/a/29926435/432509
While its noted that functions do type checking, C will coerce values too (ints/float...
How to split a column into two columns?
...s is (NaN) which will result in ValueError (to overcome this issue you can cast it to string type before splitting). I recommend you to try it on your own it's the best way of learning :-)

get list from pandas dataframe column
...then call x.tolist() on to turn them into a Python list. Alternatively you cast it with list(x).
import pandas as pd

'two': pd.Series([1, 2, 3, 4], index=['a', 'b', 'c', 'd'])}

Using current time in UTC as default value in PostgreSQL
...now()::timestamp
If your other timestamp are without time zone then this cast will yield the matching type "timestamp without time zone" for the current time.
I would like to read what others think about that option, though. I still don't trust in my understanding of this "with/without" time zone...
Should the hash code of null always be zero, in .NET
...riteLine((int)v);
it return 0, as expected, or simple Spring if we avoid casting to int.
So.. if you do the following:
Season? v = Season.Spring;
Season? vnull = null;
if(vnull == v) // never TRUE
EDIT
From MSDN
If two objects compare as equal, the GetHashCode method for each object m...
C++ static virtual members?

So, we want to provide only one definition of getTypeInformation() per derived class and it is obvious that it has to be a definition of static function because it is not possible to call "SomeDerivedClass::getType...
