What is the difference between & and && in Java?
...g if the first operand evaluates to false since the result will be false
(m>x m> != 0) & (1/m>x m> > 1) <-- this means evaluate (m>x m> != 0) then evaluate (1/m>x m> > 1) then do the &. the problem is that for m>x m>=0 this will throw an em>x m>ception.

How to do multiple arguments to map function where one remains the same in python?
...
One option is a list comprehension:
[add(m>x m>, 2) for m>x m> in [1, 2, 3]]
More options:
a = [1, 2, 3]
import functools
map(functools.partial(add, y=2), a)
import itertools
map(add, a, itertools.repeat(2, len(a)))

How to calculate an angle from three points? [closed]
...
If you mean the angle that P1 is the vertem>x m> of then using the Law of Cosines should work:
arccos((P122
+ P132 - P232) / (2 *
P12 * P13))
where P12 is the length of the segment from P1 to P2, calculated by
sqrt((P1m>x m> -
P2m>x m>)2 +
(P1y -
P2y)2)

Why are Python lambdas useful? [closed]
...
Are you talking about lambda functions? Like
lambda m>x m>: m>x m>**2 + 2*m>x m> - 5
Those things are actually quite useful. Python supports a style of programming called functional programming where you can pass functions to other functions to do stuff. Em>x m>ample:
mult3 = filter(lambda m>x m>:...
Finding local mam>x m>ima/minima with Numpy in a 1D numpy array
Can you suggest a module function from numpy/scipy that can find local mam>x m>ima/minima in a 1D numpy array? Obviously the simplest approach ever is to have a look at the nearest neighbours, but I would like to have an accepted solution that is part of the numpy distro.

How to break out from a ruby block?
...
Use the keyword nem>x m>t. If you do not want to continue to the nem>x m>t item, use break.
When nem>x m>t is used within a block, it causes the block to em>x m>it immediately, returning control to the iterator method, which may then begin a new iteration by inv...
C# LINQ find duplicates in List
...lement in the group. In LINQ, this translates to:
var query = lst.GroupBy(m>x m> => m>x m>)
.Where(g => g.Count() > 1)
.Select(y => y.Key)
.ToList();
If you want to know how many times the elements are repeated, you can use:
var query = lst.GroupBy(m>x m> =...
