Format SQL in a string (in python or any language)-CodePudding

Is there a cli tool that can be used to format SQL code inside strings in a given .py file? Example:

import foo

query = """SELECT please, format, me    

FROM    i-am-an-unformatted-query

"""

some_client.query(query)

could for example yield

import foo

query = """
SELECT
    please,
    format,
    me    
FROM i-am-an-unformatted-query"""

some_client.query(query)

ie, formatting would only occur inside the query string.

Does such a tool exist? The once I've looked at only format standalone files. I would prefer not having discussions about SQL formatting with my colleagues but align around a tool, much like we do with for example black for python formatting.

According to answer https://stackoverflow.com/a/44335609/687896, in Python you can use package sqlparse:

>>> import sqlparse
>>> sql = """SELECT please, format, me    

FROM    i-am-an-unformatted-query

"""

>>> sql_formatted = sqlparse.format(sql, reindent=True, keyword_case='upper')
>>> print(sql_formatted)
SELECT please,
       format,
       me
FROM i-am-an-unformatted-query

I mean I probably didn't get your question right but, if you're referring to formatting the query i.e : changing it based upon a request or variable you could simply use:

print( """
SELECT {},
   format, me    
FROM i-am-an-unformatted-query""",format(please))

and the print could be placed in a function that takes the please as an argument.
