I usually process simulation results in batch, which is generally associated with pathname manipulations. In this article, I take notes of pathname manipulations from my programming experiences.
This article introduces simple regression analysis illustrated with a simple example and shows how to calculate it using Python.
It is believed that the minimum connected dominating set problem cannot be solved in polynomial time. To the best of my knowledge, there is no source code available for approximation algorithms. Therefore, I decide to implement one proposed by M. Rai in 2009.
For better structuring a Python project, I decide to learn of packages, modules and classes. This article also shows how to import all modules and classes in a directory.
I am analyzing a trace in GTFS, a collection of CSV files. Each record of a csv file is consisting of one or more fields speparated by commas
,. It is error-prone to read csv files by simply using
[line.split(',') for line in f.readlines()] for fields might contain commas. Therefore, I decide to switch to the Python module csv.
I sometimes encounter problems like
TypeError: unhashable type: 'list' while programming. Therefore, I decide to set aside some time to undertand the important Python concepts, mutable, hashable and iterable.
