Sorting complex data structures in Python (similar to struct data structures in C)

There are two main functions in Python: sorted and list member functions sort, except for some differences in invocation methods, the most notable difference is that sorted creates a sorted list and returns, while sort is a good order to modify the original list. The prototype of sorted is:Sorted (iterable, Cmp=none, Key=none, Reverse=false)The prototype of sort is:List.sort (Cmp=none, Key=none, Reverse=false)Where both CMP and key are function refere

Python data structures and algorithms--list and dictionaries

ListsPython's designers have a lot of options when implementing the data structure of the list. Each choice has the potential to affect how quickly the list operation executes. Of course they also try to optimize some of the less common operations. But when it comes to tradeoffs, they sacrifice the performance of infrequently used operations to fulfill common functions.This article address: http://www.cnblogs.com/archimedes/p/
