A list of python snippets I find interesting

• The Python standard library has an implementation of Counter that is typically used to find the most common items in a a collection, with their count. I find the implement of collections.Counter instructive in general. I especially like the implementation of most_commonlink. I find it interesting how most_common determines which method to use for efficiency reasons (based on n).

• In heapq module (standard library), implemention of nsmallestlink. In general, the heapq module has awesome comments. This is true for nsmallest method also. Also, I like how this method is lazy (stores only k items irrespective of input) and generic (the optional key).
