I have had a long standing unanswered question on on stackoverflow: is it
possible to pass a function to a default parameter so that you could do in
essence things like this.
def time_diff(target_time, curr_time= lambda : datetime.now() ):
return curr_time - target_time
this would be an syntactical improvement over this style where you have if
statement to initialize a missing parameter.
def time_diff(target_time, curr_time=None):
if curr_time == None:
curr_time = datetime.datetime.now()
return curr_time - target_time
