It would be nice to add the following syntax sugar in Python "Print and Eval" like `ptev a == b` It is same as `statement = "a == b"; print(f"{statement} ? {eval(statement)}")`. It would super nice for debugging and other research project.

At the REPL, that basically already happens, but if this is something you're doing a lot of in your code, you might be able to take advantage of this feature of f-strings:
a = 5 b = 5.0 f"{a == b = }" 'a == b = True'
Very handy for quick debugging. ChrisA
Are you familiar with the f-string self-documentation operator in python 3.8? https://docs.python.org/3/whatsnew/3.8.html#f-strings-support-for-self-docum... With it you can say: print(f"{a==b=}") --- Ricky.

Hi Evan, f-strings support a version of this. If you put an equals sign at the end of the expression in your f-string (possibly with white space) then the f-string will include both the expression itself and its value in the result: >>> a = 12; b = 13 >>> f'{a == b}' 'False' >>> f'{a == b = }' 'a == b = False' -- Steve
