I saved this solution for looking it up later because I like it a lot, but honestly, I have no idea what is happening here. Can you please advise on what topics I should look up? My current understanding is that you assigned the import method to a variable with numpy hardcoded for its parameter but it's very unclear, how does this work. A variable can contain a function, that was new to me, also that I even can pass parameters to such variable somehow. Also the .median suppose to be a method as far as know whereas here it looks like a direct property access for me. I failed to test my assumptions like these: <pre class='brush: python'>def fuction(x): return x variable = function("test") print(variable) </pre>

Hi, there are few things: <ol> <li>The <a href="https://docs.python.org/3/library/functions.html?highlight=__import__#__import__"><pre class='brush: python'>__import__</pre></a> function actually imports the <pre class='brush: python'>numpy</pre> module. It's as if you did <pre class='brush: python'>import numpy</pre>.</li> <li><pre class='brush: python'>__import__("numpy")</pre> is basically the equivalent to <pre class='brush: python'>import numpy;numpy.median</pre>.</li> <li>Function are first class citizens in Python so you can for example assign a function to a variable.</li> </ol> This one-liner combines the three things together. Regards, suic ```python <h1>Ad 3</h1> def my_function(x): return x myfunctionwithadifferentname = myfunction <h1>You can use lambda or an additional def for this, but both are superfluous:</h1> def myfunctionwithadifferentname(x): return myfunction(x) myfunctionwithadifferentname = lambda x: myfunction(x)
