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

can't solve this(

Could anybody help with the task?

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(*args):
    oldest = timestamp_oldest[0]
    for var in *args:
        if var < oldest:
            oldest = var
    return oldest

The challenge can be solved in 4 steps.

Step1: Create a function that accepts any number of arguments.

def timestamp_oldest(*args):

Step2: Since we do not know how many arguments will be given, we'll create a list and append all the arguments into that.

timestamps = []
for value in args:
    timestamps.append(value)

Step3: We need to sort the list to get the smallest number because the smallest number is the closest to the EPOC time.

timestamps.sort()

Step4: Let's now convert the POSIX timestamp to a Datetime timestamp by using fromtimestamp() method.

return datetime.datetime.fromtimestamp(timestamps[0])

If you need more clarification let me know.

I've got it, thank you so much
