I needed to convert dates to ISO-8601 calendar week and year in a bash script. This is what I came up with:
#!/usr/bin/env python import optparse import datetime parser = optparse.OptionParser() _, args = parser.parse_args() y, w, _ = datetime.datetime.strptime(args[0], "%Y/%m/%d").isocalendar() print "%d/%02d" % (y, w)
It takes input from the command line as YYYY/MM/DD and outputs YYYY/WW.

Great post! Helpful! Do you have code to take YYYY/WW as an input and return YYYY/MM/DD? Maybe the start of the week?
