>>> time1 = datetime.datetime.now()
>>> time2 = datetime.datetime.now() # waited a few minutes before pressing enter
>>> elapsedTime = time2 - time1
>>> elapsedTime
datetime.timedelta(0, 125, 749430)
>>> divmod(elapsedTime.total_seconds(), 60)
(2.0, 5.749430000000004) # divmod returns quotient and remainder
# 2 minutes, 5.74943 seconds

Example 2: python get dates between two dates

from datetime import datetime, timedelta

def date_range(start, end):
    delta = end - start  # as timedelta
    days = [start + timedelta(days=i) for i in range(delta.days + 1)]
    return days

start_date = datetime(2008, 8, 1)
end_date = datetime(2008, 8, 3)
    
print(date_range(start_date, end_date))

Example 3: pytthon how many fridays´ between two dates

from datetime import  date

d1 = date(2017, 1, 4)
d2 = date(2017, 1, 31)

count = 0

for d_ord in range(d1.toordinal(), d2.toordinal()):
    d = date.fromordinal(d_ord)
    if (d.weekday() == 4):
        count += 1

print(count)
