Python Dates and Times in Python (2014) Let's Build a Timed Quiz App Timestamp Ordering

How do I return the oldest POSIX timestamp? The method I'm running is returning a tuple not an integer...

I know I've run into this problem before with multiple arguments before, but I'm stuck on how to solve it.

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

import datetime

def timestamp_oldest(*POSIX):
    timestamps = []
    for timestamp in POSIX:
        timestamps.append(POSIX)
    timestamps.sort()
    oldest = timestamps[0]
    return datetime.datetime.fromtimestamp(oldest)

Hey Travers Geoffray, there is an error in the loop append.

Need to append timestamp instead of POSIX

There is a simpler way to sort the arguments. The built-in function sorted returns a list and works on iterable objects.

timestamps = sorted(POSIX)

Post back if you need more help. Good luck!!!

That worked, thank you! And thanks for showing me that sorted function.
