I'm trying to subtract a day from this date 06-30-2019 in order to make it 06-29-2019 but can't figure out any way to achive that.

date = "06-30-2019"
date = datetime.datetime.strptime(date,'%m-%d-%Y').strftime('%m-%d-%Y')
print(date)

It surely gives me back the date I used above.

import datetime

date = "06/30/19" 
date = datetime.datetime.strptime(date, "%m/%d/%y") 
NewDate = date + datetime.timedelta(days=-1)

print(NewDate)  # 2019-06-29 00:00:00
