WHERE b=1

after I excute the order
$ pybabel extract -F babel.cfg -o messages.pot .

but I cannot find the words 'abc' from file messages.pot

The underlying Babel library does not support f-strings. You will need to raise an issue with them and/or add support in https://github.com/python-babel/babel/blob/master/babel/messages/extract.py#L581 to extract function usage inside a f-string AST node.
