Unexplained Invalid syntax Error

[cybertooth]

i am working on a Order form with tkinter. The first draft worked well, I wanted to add current date display on the form. When i run it I get a Syntax Error " invalid syntax" highlighting the "toothnumbervalue" I am a beginner in python . i have gone through the code several times but am unable to locate the cause of the error . Can somebody please show me the way.

Please post the error in its entirety, as it gives the line number and a pointer to what the problem is.

I am not getting any trace back its only a pop up message saying invalid syntax.

I don't know what you're doing to run the program, so just run it on the command line and you should get a traceback.

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

Error:
λ python tk_test.py
  File "G:\div_code\tk_test.py", line 9
    (labnamevalue.get(),patientnamevalue.get(), workvalue.get(), toothnumbervalue.get(), materialvalue.get(), shadevalue.get(), labservicevalue.get(),orderdatevalue.(dt.datetime.now():%a, %b %d %Y))

                      ^
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 >>> >>> d = f'{(dt.datetime.now():%a, %b %d %Y)}'   File "<interactive input>", line 1     ((dt.datetime.now():%a, %b %d %Y))                        ^ SyntaxError: f-string: invalid syntax   # Fix >>> d = f'{dt.datetime.now():%a, %b %d %Y}' >>> d 'Sat, Jul 31 2021

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