[Tkinter] ClockIn/Out tkinter problem

I will appreciate any help. I got stuck with hours to find the solution.

What is the problem? When I press the "Clock In" button I get an error.
Error:
Exception in Tkinter callback Traceback (most recent call last): File "C:\Program Files\Python38\lib\tkinter\__init__.py", line 1883, in __call__ return self.func(*args) File "...\musings\junk.py", line 94, in <lambda> btn1 = Button(root, text='Clock In', command=lambda :[sw.Start(), sw.clock_in()]) File "...\musings\junk.py", line 64, in clock_in with open(self.filename, "a") as savedb: AttributeError: 'StopWatch' object has no attribute 'filename'
But this cannot be the problem you are having because it has such an obvious cause. You never specify a value for self.filename, so of course you will get an attribute error when you try to get something that is not an attribute of self.

So I commented out where the code writes the file with no name an instead had the code do this.
        totalinput = [ data, ClockIn_time, ClockIn_date]
        print(totalinput)
##        with open(self.filename, "a") as savedb:
##            w = csv.writer(savedb)
##            w.writerow(totalinput)
I did the same for clock_out(). Now when I press the Clock In and Clock Out buttons I get this.
Output:
['Jack', datetime.datetime(2020, 10, 9, 17, 33, 53, 33651), '2020-10-09'] ['Jack', datetime.datetime(2020, 10, 9, 17, 33, 58, 648473), '2020-10-09']
I entered 'Jack' as the employee name. Is this what you want written to the unnamed file? Looks about right to me.

To fix your problem you need to somewhere in you code do this:
self.filename = 'some string'
If the particular problem you are having is something else, you need to provide more information.

Hey,
A couple of modifications- added the filename with the suffix .cvs, moved your entry and label into the make widgets method changed the timer update method to show the building of time. removed the lambda in the main. You have functions lambda is for lazy people that don't write functions( they have their place).

Now what's left: 
this timer is only set up for 59 minutes which would be great if a job only lasted that long, so you'll need to add some hours but that shouldn't be to difficult. 
You may need a check to see if there's a name in the entry widget.
Maybe set up the cvs with columns and titles to make easy to read.
Clean up the data written to cvs so accounting doesn't need a CS to decipher it.
