[issue38568] [3.7.5 x86_64 Linux] f-string parsing results in EOL

[Ying Wang]

New submission from Ying Wang :

Hey,

I encountered an interesting bug when trying to do string parsing using 
f-strings. I am currently under the impression that within the curly braces is 
any expression that can be successfully evaluated in a REPL. Here's the error:

```bash
yingw787@yingw787-Oryx-Pro:~/src/gpudb-dev-v6.2.0/kio/kio/tests/regression/_data/csv$
 python
Python 3.7.5 (default, Oct 15 2019, 21:38:37) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> blah = '"hi"'
>>> blah
'"hi"'
>>> f'{blah.strip('"')}'
  File "", line 1
f'{blah.strip('"')}'
   ^
SyntaxError: EOL while scanning string literal
>>> '{0}'.format(blah.strip('"'))
'hi'
>>> 
```

I can use '.format()' for now, but it might be nice to align f-string expr 
behavior w/ .format(). Please let me know if you need more reproduction steps, 
or if you need a helping hand :)

Thanks
Ying

Oh cool, I didn't know triple quotes can be used as part of f-strings! Thanks 
for the explanation!

@rhettinger should this issue be closed if no action is to be taken? If so, 
should I manually close the pull request referencing this issue, or will that 
be automatically handled by the Python bug tracker?
