$ pip install sqlparse

>>> import sqlparse
>>> # Split a string containing two SQL statements:
>>> raw = 'select * from foo; select * from bar;'
>>> statements = sqlparse.split(raw)
>>> statements
['select * from foo;', 'select * from bar;']
>>> # Format the first statement and print it out:
>>> first = statements[0]
>>> print(sqlparse.format(first, reindent=True, keyword_case='upper'))
SELECT *
FROM foo;
>>> # Parsing a SQL statement:
>>> parsed = sqlparse.parse('select * from foo')[0]
>>> parsed.tokens
[<DML 'select' at 0x7f22c5e15368>, <Whitespace ' ' at 0x7f22c5e153b0>, <Wildcard '*' … ]
>>>

sqlparse can be used as a pre-commit hook to automatically format SQL files before committing:

repos:
  - repo: https://github.com/andialbrecht/sqlparse
    rev: 0.5.4  # Use the latest version
    hooks:
      - id: sqlformat
        # Optional: Add more formatting options
        # IMPORTANT: --in-place is required, already included by default
        args: [--in-place, --reindent, --keywords, upper]

Then install the hook:

$ pre-commit install

Your SQL files will now be automatically formatted on each commit.

Note: The hook uses --in-place --reindent by default. If you override the args, you must include --in-place for the hook to work.
