Oh so this is how you would write it using 2 lambdas. How would you do it using def and return? Still trying to figure out how to do it all in 2 lines. I am still learning but here is what i published. <pre class='brush: python'>def bigger_price(l, d): r = sorted(d, key=lambda k: -k['price']) return r[:l] </pre>

Hi, in fact <pre class='brush: python'>r</pre> is redundant. <pre class='brush: python'>sorted()</pre> returns a sorted list, which can be sliced. The transformation to <pre class='brush: python'>def</pre> + <pre class='brush: python'>return</pre> is therefore trivial: <pre class='brush: python'>def bigger_price(l, d): return sorted(d, key=lambda e: -e["price"])[:l] </pre> Regards, suic
