Why doesn't my variable change every time the for loop runs?

I know date_list contains different datetime objects, so that's not the problem, but when link_list is printed, the same string is printed multiple times. Therefore, link is only ever the first date of the date_list.

for date in date_list:
    link = link.format(date.strftime(link_format))
    print(link)
    link_list.append(link)
print(link_list)
break

I solved it by doing this, but I'd like to know why link didn't update.

for date in date_list:
    link_list.append(link.format(date.strftime(link_format)))
print(link_list)
break

link is not defined before in line 2.

for date in date_list:
    link = link.format(date.strftime(link_format))
    print(link)
    link_list.append(link)
print(link_list)
break
