I am trying to create a list that is generated by using list comprehension that uses 1 minute increments. Then it would convert the dates/times into the ISO 8601 format. This is what I was thinking the solution would look like:

import datetime as dt

t1 = dt.datetime(2001, 10, 10, 0, 0, 0)

t2 = dt.datetime(2001, 10, 15, 0, 0, 0)

time = [t1 + dt.timedelta(minutes = x) for x in range((t2-t1).total_seconds()/60)]

isotime = time.isoformat()

Is this semi correct?

think this might be easier using pandas:

import pandas as pd
t1 = pd.to_datetime('2001-10-10 00:00:00')
t2 = pd.to_datetime('2001-10-15 00:00:00')
series = pd.date_range(t1,t2,freq='1min')
iso8601 = [t.strftime('%Y%m%dT%H:%M%SZ') for t in series]


['20011010T00:0000Z', '20011010T00:0100Z', '20011010T00:0200Z', '20011010T00:0300Z', ... ,  
'20011014T23:5700Z', '20011014T23:5800Z', '20011014T23:5900Z', '20011015T00:0000Z']

Python: List Comprehension For Date and Time – stb-test-automation, Python: List Comprehension For Date and Time. [ create a list. '%02d:%02d' format to a two-digit number with a leading zero. current_timestamp+timedelta(minutes=10*x)).hour. for x in xrange(0,24*60/10) Here's a slightly different answer building off of S.Lott's answer that gives a list of dates between two dates start and end. In the example below, from the start of 2017 to today. start = datetime.datetime(2017,1,1) end = daterange = [start + datetime.timedelta(days=x) for x in range(0, (end-start).days)]

You need to apply isoformat on every item in the time list:

isotime = [t.isoformat() for t in time]

Also note that range accepts only integers. You should change range((t2-t1).total_seconds()/60) to range(int((t2-t1).total_seconds()/60))

Though, the best thing is to use pandas as @Derek Eden suggested.

(Tutorial) Python List Comprehension, Learn how to effectively use list comprehension in Python to create lists, into nested list comprehensions to iterate multiple times over lists. Using list comprehension in functions. Now, let’s see how we can use list comprehension in functions. # Create a function and name it double: def double(x): return x*2 # If you now just print that function with a value in it, it should look like this: >>> print double(10) 20 We can easily use list comprehension on that function.

  • What exactly are you trying to achieve? Can you post what you expect isotime to be?
  • Instead of asking us, why not print out the list and see?
  • Your solution does not work for me.
  • Since you have 5 days - are you looking for a list of 7200 entries?
  • I can use this as well since the boss doesn't care if I use pandas or not, thanks for the other method!!
