Timing, and memory, on Linux
Timing
On Linux, it's safer to use time.time()
import time t = time.time() # do some stuff print "stuff took %1.3f", time.time() - t, "seconds"
On Windows, AFAIK, it's safer to use time.clock()
Memory
For me, the following does a good job getting memory usage (in kB) on Linux:
import resource print resource.getrusage(resource.RUSAGE_SELF).ru_maxrss
Since resource is standard package, it should work on Windows too, but I don't know if it does, or what units are used if it works.
Importing Files
If you need to import a file '../mylib/commons.py', you can use the following snippet:
fld = os.path.realpath(os.path.abspath(os.path.join('..', 'mylib')))
if fld not in sys.path:
sys.path.insert(0, fld)
import commons
# use your commons.py module now...
commons.super_function()
