Alternative to numpy.random.poisson() for drawin a SINGLE poisson distributed random number | 39,012,787 | <p>I noticed that drawing <strong>single</strong> random numbers using <code>numpy.random</code> is generally way slower than using <code>random</code>, obviously because <code>numpy.random</code> is optimized for drawing a bunch of random numbers in one shot. E.g., timings for sampling a random integer from a list are... | 0 | 2016-08-18T07:59:54Z | 39,014,499 | <p>You can create all values at once by passing in an iterable of lambdas:</p>
<pre><code>numpy.random.poisson(lam=numpy.arange(200), size=(100, 200))
</code></pre>
<p>this will return 100 values for each of the 200 different lambda (100 * 200 values in total) values in one execution.</p>

| -1 | 2016-08-18T08:07:00Z | 39,013,048 | <p>You can use a loop and check if, at each index of your array, the value is corresponding to a number.
Use ascii code ( code 48 to 57 for 0 to 9)
If the ascii code of your value is between 48 and 57, you know it's a number.
If not, you know it's not a number.</p>
