I don't know how to do this one.

I'm not sure how to answer this question at all. This is in the python course.

Please help.

Thanks.

timestamp.py 
# If you need help, look up datetime.datetime.fromtimestamp()
# Also, remember that you *will not* know how many timestamps
# are coming in.

The key to this one is that timestamps is coming in as a variable number of arguments (we'll call it *timestamps)

There are lots of different ways to do this challenge, but a workable approach is this

  • make sure to import datetime
  • declare the function and fill in the steps 1, 2, 3.
import datetime
def timestamp_oldest(*timestamps):
    # 1) convert to a list
    # 2) sort the list
    # 3) oldest = first item in the list
    return datetime.datetime.fromtimestamp(oldest)
