named parameters for bash function

function myFunc {
  while [[ $# -gt 0 ]]; do local "$1"; shift; done
  #require paramName
}
myFunc paramName=paramValue

Now you can have named parameters for your bash functions, it made my library more useful since the script will be more readable. For compulsory parameters, you should check if it has been set or not. Some people do “local $*” instead of the while loop, but it will not work with parameters like paramName=”value with space”.

Python strptime and number of week in the year

from datetime import datetime
d = datetime(2012, 4, 10, 0, 0, 0)
d_str = d.strftime('%Y%W')
# d_str = '201215'
dw = datetime.strptime(d_str, '%Y%W')
# dw = datetime.datetime(2012, 1, 1, 0, 0) <----- WHY?

# to make %W work, you have to use it together with %w
dw = datetime.strptime(d_str+' 0', '%Y%W %w')
# dw = datetime.datetime(2012, 4, 15, 0, 0)
