var obj = {
someProperty: true,
someMethod: function() {
console.log(this.someProperty);
}
};

Concatenating two one-dimensional NumPy arrays
...to concatenate need to passed in as a sequence, not as separate arguments.
From the NumPy documentation:
numpy.concatenate((a1, a2, ...), axis=0)
Join a sequence of arrays together.
It was trying to interpret your b as the axis parameter, which is why it complained it couldn't convert it into a sc...
Can you change what a symlink points to after it is created?
... = 0
So I guess the final answer is "no".

Using this library is simple. Here are some examples of conversion:...
How to determine if a point is in a 2D triangle? [closed]
... Kisielewicz answer. I looked into the Barycentric method also but judging from the Wikipedia article I have a hard time seeing how it is more efficient (I'm guessing there is some deeper equivalence). Anyway, this algorithm has the advantage of not using division; a potential problem is the behavio...
Why aren't programs written in Assembly more often? [closed]
