how to crate a list of days from x date till y date by adding 7 days?

Question

I have tried this code but showing nothing while checking the list length

from datetime import date
from datetime import timedelta
sdate= date(1990,10,25)
tdate=date(1990,10,25)
i=7
rqd_dt=[]
adate = date(2022,12,31)
while adate > tdate:
    rqd_dt.append(tdate)
    tdate = sdate+timedelta(days=i)  
print(len(rqd_dt))

Answer 1

You have a small mistake only. Change this line:

tdate = sdate+timedelta(days=i) to tdate = tdate+timedelta(days=i)

This way, tdate keeps incrementing by 7 days. As you had it, tdate remains the same every loop, so it's not stuck at the print statement - it's stuck in an infinite loop. If you added a little investigative print statement inside your while loop, you would see this.
