why import time 2x

[ilcaa72]

just need a quick explanation on why if i imported time from datetime in line 2, do i need to import again in line 3 to make this work?

ctime wont appear if i dont import time on its own line... as a newbie, just a little confused

import datetime
from datetime import date, time, timedelta
import time

mtime= path.getmtime('textfile.txt')
t = time.ctime((mtime) )
print(t)
