Average timedelta in list

Question

I want to calculate the avarage timedelta between dates in a list. Although the following works well, I\'m wondering if there\'s a smarter way?

delta = lambd         


        

Answer 1

Btw, if you have a list of timedeltas or datetimes, why do you even do any math yourself?

datetimes = [ ... ]

# subtracting datetimes gives timedeltas
timedeltas = [datetimes[i-1]-datetimes[i] for i in range(1, len(datetimes))]

# giving datetime.timedelta(0) as the start value makes sum work on tds 
average_timedelta = sum(timedeltas, datetime.timedelta(0)) / len(timedeltas)
