How to check an IP address is within a range of two IPs in PHP?
With ip2long() it’s easy to convert your addresses to numbers. After this, you just have to check if the number is in range: if ($ip <= $high_ip && $low_ip <= $ip) { echo “in range”; }
range
Python range() and zip() object type
You must be using Python 3. In Python 2, the objects zip and range did behave as you were suggesting, returning lists. They were changed to generator-like objects which produce the elements on demand rather than expand an entire list into memory. One advantage was greater efficiency in their typical use-cases (e.g. iterating over them). … Read more

How to select values within a provided index range from a List using LINQ
Use Skip then Take. yourEnumerable.Skip(4).Take(3).Select( x=>x ) (from p in intList.Skip(x).Take(n) select p).sum()
Creating an Array from a Range in VBA
Just define the variable as a variant, and make them equal: Dim DirArray As Variant DirArray = Range(“a1:a5”).Value No need for the Array command.
Why is range(0) == range(2, 2, 2) True in Python 3?
The range objects are special: Python will compare range objects as Sequences. What that essentially means is that the comparison doesn’t evaluate how they represent a given sequence but rather what they represent. The fact that the start, stop and step parameters are completely different plays no difference here because they all represent an empty … Read more
Skip over a value in the range function in python
You can use any of these: # Create a range that does not contain 50 for i in [x for x in xrange(100) if x != 50]: print i # Create 2 ranges [0,49] and [51, 100] (Python 2) for i in range(50) + range(51, 100): print i # Create a iterator and skip 50 … Read more
built-in range or numpy.arange: which is more efficient?
For large arrays, a vectorised numpy operation is the fastest. If you must loop, prefer xrange/range and avoid using np.arange. In numpy you should use combinations of vectorized calculations, ufuncs and indexing to solve your problems as it runs at C speed. Looping over numpy arrays is inefficient compared to this. (Something like the worst … Read more
How to check if an integer is within a range?
Tested your 3 ways with a 1000000-times-loop. t1_test1: ($val >= $min && $val <= $max): 0.3823 ms t2_test2: (in_array($val, range($min, $max)): 9.3301 ms t3_test3: (max(min($var, $max), $min) == $val): 0.7272 ms T1 was fastest, it was basicly this: function t1($val, $min, $max) { return ($val >= $min && $val <= $max); }
