    ...data types. While this feature allows for quick and flexible code, it is the responsibility of the programmer to make explicit the data types that a function expects. A standard coding style that names variables according to their expected data type is an easy way to address this problem.

  • Python Patterns - Implementing Graphs

    ...data type, and Python is no exception. However, graphs are easily built out of lists and dictionaries. For instance, here's a simple graph (I can't use drawings in these columns, so I write down the graph's arcs): A -> B A -> C B -> C B -> D C -> D D -> C E -> F F -> C This graph has six nodes (A-F) and eight arcs. It can be represented by the following Python data structure: graph = {'A': ['B', 'C'], 'B': ['C', 'D'],...

  • What is Python? Executive Summary

    ...data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are avai...

    ...data types of the keys in the Property manager dictionary without any extra effort at all. Yet, as described above, Python does at the same time provide sufficient data type checking to find many kinds of common type mismatch errors. One of the factors that made our Property manager so successful was that Python lets user-defined types emulate the behavior of built-in types. Our Property manager acts very much like a lookup table that maps property name to value, so we designed it to emulate a P...

I was worried that the quadratic behavior of the algorithm was killing us. So far, we had been using a list of 256 integers as test data, since that was what my friend needed the function for. But what if it were applied to a list of two thousand characters? We'd be concatenating longer and longer string...
