Python Generating A List Of Dates Between Two Dates

I want to generate a list of dates between two dates and store them in a list in string format. This list is useful to compare with other dates I have. My code is given below: fr

Solution 1:

You can use pandas.date_range() for this:

import pandas
pandas.date_range(sdate,edate-timedelta(days=1),freq='d')

---

DatetimeIndex(['2019-03-22', '2019-03-23', '2019-03-24', '2019-03-25',
           '2019-03-26', '2019-03-27', '2019-03-28', '2019-03-29',
           '2019-03-30', '2019-03-31', '2019-04-01', '2019-04-02',
           '2019-04-03', '2019-04-04', '2019-04-05', '2019-04-06',
           '2019-04-07', '2019-04-08'],
          dtype='datetime64[ns]', freq='D')

Solution 2:

Your code rewritten as a list comprehension:

[sdate+timedelta(days=x) for x in range((edate-sdate).days)]

results:

[datetime.date(2019, 3, 22),
 datetime.date(2019, 3, 23),
 datetime.date(2019, 3, 24),
          :
 datetime.date(2019, 4, 7),
 datetime.date(2019, 4, 8)]

Solution 3:

You'd need to turn it into a list with strings explicitly:

print([str(d) for d in dates_bwn_twodates(sdate,edate)])

Solution 4:

from datetime import date, timedelta

sdate = date(2019,3,22)   # start date
edate = date(2019,4,9)   # end date
date_modified=sdate
list=[sdate] 


while date_modified<edate:
    date_modified+=timedelta(days=nbDaysbtw2dates) 
    list.append(date_modified)

print(list) 

Solution 5:

You can use the moment library from https://github.com/zachwill/moment.git to make your life easier.

import moment

def dates_bwn_twodates(start_date, end_date):
    diff = abs(start_date.diff(end_date).days)
    
    for n in range(0,diff+1):
        yield start_date.strftime("%Y-%m-%d")
        start_date = (start_date).add(days=1)

sdate = moment.date('2019-03-22')   #start date
edate = moment.date('2019-04-09')   #end date  

and then you have options

dates = list(dates_bwn_twodates(sdate,edate)) #dates as a list

or you can iterate

for date in dates_bwn_twodates(sdate,edate):
    #do something with each date
