Unexplained Invalid syntax Error

[cybertooth]

thanks a lot snippsat. It worked.

There are SyntaxError in both in print and write.
As mention bye ndc85430 Traceback should show this.

Error:

                      ^
SyntaxError: f-string: invalid syntax

Can no do this orderdatevalue. is a attribute access and call it with tuple with date object inside will never work.
Also can not use tuple around date object inside a f-string.

>>> import datetime as dt
>>>

                       ^
SyntaxError: f-string: invalid syntax

# Fix
>>> d = f'{dt.datetime.now():%a, %b %d %Y}'
>>> d

Test increment with smaller step as you new to this,also line of length 210 character is way to long.
