I’ve finally made the migration away from make and the horrible system of autofoo and Makefiles. A few years ago I discovered a build system called waf that does everything make can do, only better!
Today was the start of my internship in Boulder, CO at NCAR (The National Center for Atmospheric Research) in the SiParCS 2009 summer internship program. It was mostly filled with administrative and logistical stuff, but I did get a few hours of working on my project in.
I was interested in the relative performance of reversing a python list using the idom list[::-1] rather than the reverse method of the list class. Additionally I wanted to see if this idom was efficient for reversing strings compared to converting to a list, reversing that list, and joining the elements again using ''.join(reversed_list). Here are the results:
Reverse list, slicing: (0.58000000000000007, 0.64144396781921387)
Reverse list, method: (0.20000000000000018, 0.19551301002502441)
Reverse string, slicing: (0.45000000000000001, 0.49545693397521973)
Reverse string, list: (3.71, 3.7981550693511963)
