Java Generate Random Number Between Two Given Values [duplicate]
...ystem.out.println(Random);
}
If You want to specify a more decent range, like from 10 to 100 ( both are in the range )
so the code would be :
int Random =10 + (int)(Math.random()*(91));
/* int Random = (min.value ) + (int)(Math.random()* ( Max - Min + 1));
*Where min is the smal...
What's the most elegant way to cap a number to a segment? [closed]
...mp function:
/**
* Returns a number whose value is limited to the given range.

* Example: limit the output of this computation to between 0 and 255
* (x * 255).clamp(0, 255)

* @param {Number} max The upper boundary of the outp...
Split array into chunks
...
My preferred way nowadays is the above, or one of the following:
Array.range = function(n) {
// Array.range(5) --> [0,1,2,3,4]
return Array.apply(null,Array(n)).map((x,i) => i)
};
Object.defineProperty(Array.prototype, 'chunk', {
value: function(n) {
// ACTUAL CODE FOR CHUNKING...

Access multiple elements of list knowing their index
...hList, ind: [searchList[i] for i in ind]
using the following input:
a = range(0, 10000000)
b = range(500, 500000)
simple python loop was the quickest with lambda operation a close second, mapIndexValues and getIndexValues were consistently pretty similar with numpy method significantly slower a...

Convert a list to a dictionary in Python
...mprehension, but ironically I think the simplest way to do it will be with range() and len(), which would normally be a code smell.
b = {a[i]: a[i+1] for i in range(0, len(a), 2)}
So the iter()/izip() method is still probably the most Pythonic in Python 3, although as EOL notes in a comment, zip(...
