status](https://github.com/asottile/pyupgrade/actions/workflows/main.yml/badge.svg)](https://github.com/asottile/pyupgrade/actions/workflows/main.yml) [![pre-commit.ci status](https://results.pre-commit.ci/badge/github/asottile/pyupgrade/main.svg)](https://results.pre-commit.ci/latest/github/asottile/pyupgrade/main) pyupgrade ========= A tool (and pre-commit hook) to automatically upgrade syntax for newer versions of the language. ## Installation ```bash pip install pyupgrade ``` ## As a pre-commit hook See [pre-commit](https://github.com/pre-commit/pre-commit) for instructions Sample `.pre-commit-config.yaml`: ```yaml - repo: https://github.com/asottile/pyupgrade rev: v3.21.0 hooks: - id: pyupgrade ``` ## Implemented features ### Set literals ```diff -set(()) +set() -set([]) +set() -set((1,)) +{1} -set((1, 2)) +{1, 2} -set([1, 2]) +{1, 2} -set(x for x in y) +{x for x in y} -set([x for x in y]) +{x for x in y} ``` ### Dictionary comprehensions ```diff -dict((a, b) for a, b in y) +{a: b for a, b in y} -dict([(a, b) for a, b in y]) +{a: b for a, b in y} ``` ### Replace unnecessary lambdas in `collections.defaultdict` calls ```diff -defaultdict(lambda: []) +defaultdict(list) -defaultdict(lambda: list()) +defaultdict(list) -defaultdict(lambda: {}) +defaultdict(dict) -defaultdict(lambda: dict()) +defaultdict(dict) -defaultdict(lambda: ()) +defaultdict(tuple) -defaultdict(lambda: tuple()) +defaultdict(tuple) -defaultdict(lambda: set()) +defaultdict(set) -defaultdict(lambda: 0) +defaultdict(int) -defaultdict(lambda: 0.0) +defaultdict(float) -defaultdict(lambda: 0j) +defaultdict(complex) -defaultdict(lambda: '') +defaultdict(str) ``` ### Format Specifiers ```diff -'{0} {1}'.format(1, 2) +'{} {}'.format(1, 2) -'{0}' '{1}'.format(1, 2) +'{}' '{}'.format(1, 2) ``` ### printf-style string formatting Availability: - Unless `--keep-percent-format` is passed. ```diff -'%s %s' % (a, b) +'{} {}'.format(a, b) -'%r %2f' % (a, b) +'{!r} {:2f}'.format(a, b) -'%(a)s %(b)s' % {'a': 1, 'b': 2} +'{a} {b}'.format(a=1, b=2) ``` ### Unicode literals ```diff -u'foo' +'foo' -u"foo" +'foo' -u'''foo''' +'''foo''' ``` ### Invalid escape sequences ```diff # strings with only invalid sequences become raw strings -'\d' +r'\d' # strings with mixed valid / invalid sequences get escaped -'\n\d' +'\n\\d' -u'\d' +r'\d' # this fixes a syntax error in python3.3+ -'\N' +r'\N' ``` ### `is` / `is not` comparison to constant literals In python3.8+, comparison to literals becomes a `SyntaxWarning` as the success of those comparisons is implementation specific (due to common object caching). ```diff -x is 5 +x == 5 -x is not 5 +x != 5 -x is 'foo' +x == 'foo' ``` ### `.encode()` to bytes literals ```diff -'foo'.encode() +b'foo' -'foo'.encode('ascii') +b'foo' -'foo'.encode('utf-8') +b'foo' -u'foo'.encode() +b'foo' -'\xa0'.encode('latin1') +b'\xa0' ``` ### extraneous parens in `print(...)` A fix for [python-modernize/python-modernize#178] ```diff # ok: printing an empty tuple print(()) # ok: printing a tuple print((1,)) # ok: parenthesized generator argument sum((i for i in range(3)), []) # fixed: -print(("foo")) +print("foo") ``` [python-modernize/python-modernize#178]: https://github.com/python-modernize/python-modernize/issues/178 ### constant fold `isinstance` / `issubclass` / `except` ```diff -isinstance(x, (int, int)) +isinstance(x, int) -issubclass(y, (str, str)) +issubclass(y, str) try: raises() -except (Error1, Error1, Error2): +except (Error1, Error2): pass ``` ### unittest deprecated aliases Rewrites [deprecated unittest method aliases](https://docs.python.org/3/library/unittest.html#deprecated-aliases) to their non-deprecated forms. ```diff from unittest import TestCase class MyTests(TestCase): def test_something(self): - self.failUnlessEqual(1, 1) + self.assertEqual(1, 1) - self.assertEquals(1, 1) + self.assertEqual(1, 1) ``` ### `super()` calls ```diff class C(Base): def f(self): - super(C, self).f() + super().f() ``` ### "new style" classes #### rewrites class declaration ```diff -class C(object): pass +class C: pass -class C(B, object): pass +class C(B): pass ``` #### removes `__metaclass__ = type` declaration ```diff class C: - __metaclass__ = type ``` ### forced `str("native")` literals ```diff -str() +'' -str("foo") +"foo" ``` ### `.encode("utf-8")` ```diff -"foo".encode("utf-8") +"foo".encode() ``` ### `# coding: ...` comment as of [PEP 3120], the default encoding for python source is UTF-8 ```diff -# coding: utf-8 x = 1 ``` [PEP 3120]: https://www.python.org/dev/peps/pep-3120/ ### `__future__` import removal Availability: - by default removes `nested_scopes`, `generators`, `with_statement`, `absolute_import`, `division`, `print_function`, `unicode_literals` - `--py37-plus` will also remove `generator_stop` ```diff -from __future__ import with_statement ``` ### Remove unnecessary py3-compat imports ```diff -from io import open -from six.moves import map -from builtins import object # python-future ``` ### import replacements Availability: - `--py36-plus` (and others) will replace imports see also [reorder-python-imports](https://github.com/asottile/reorder_python_imports#removing--rewriting-obsolete-six-imports) some examples: ```diff -from collections import deque, Mapping +from collections import deque +from collections.abc import Mapping ``` ```diff -from typing import Sequence +from collections.abc import Sequence ``` ```diff -from typing_extensions import Concatenate +from typing import Concatenate ``` ### rewrite `mock` imports Availability: - [Unless `--keep-mock` is passed on the commandline](https://github.com/asottile/pyupgrade/issues/314). ```diff -from mock import patch +from unittest.mock import patch ``` ### `yield` => `yield from` ```diff def f(): - for x in y: - yield x + yield from y - for a, b in c: - yield (a, b) + yield from c ``` ### Python2 and old Python3.x blocks ```diff import sys -if sys.version_info < (3,): # also understands `six.PY2` (and `not`), `six.PY3` (and `not`) - print('py2') -else: - print('py3') +print('py3') ``` Availability: - `--py36-plus` will remove Python <= 3.5 only blocks - `--py37-plus` will remove Python <= 3.6 only blocks - so on and so forth ```diff # using --py36-plus for this example import sys -if sys.version_info < (3, 6): - print('py3.5') -else: - print('py3.6+') +print('py3.6+') -if sys.version_info <= (3, 5): - print('py3.5') -else: - print('py3.6+') +print('py3.6+') -if sys.version_info >= (3, 6): - print('py3.6+') -else: - print('py3.5') +print('py3.6+') ``` Note that `if` blocks without an `else` will not be rewritten as it could introduce a syntax error. ### remove `six` compatibility code ```diff -six.text_type +str -six.binary_type +bytes -six.class_types +(type,) -six.string_types +(str,) -six.integer_types +(int,) -six.unichr +chr -six.iterbytes +iter

-six.ensure_str('...') +'...' -six.ensure_text('...') +'...' ``` ### `open` alias ```diff -with io.open('f.txt') as f: +with open('f.txt') as f: ... ``` ### redundant `open` modes ```diff -open("foo", "U") +open("foo") -open("foo", "Ur") +open("foo") -open("foo", "Ub") +open("foo", "rb") -open("foo", "rUb") +open("foo", "rb") -open("foo", "r") +open("foo") -open("foo", "rt") +open("foo") -open("f", "r", encoding="UTF-8") +open("f", encoding="UTF-8") -open("f", "wt") +open("f", "w") ``` ### `OSError` aliases ```diff # also understands: # - IOError # - WindowsError # - mmap.error and uses of `from mmap import error` # - select.error and uses of `from select import error` # - socket.error and uses of `from socket import error` def throw(): - raise EnvironmentError('boom') + raise OSError('boom') def catch(): try: throw() - except EnvironmentError: + except OSError: handle_error() ``` ### `TimeoutError` aliases Availability: - `--py310-plus` for `socket.timeout` - `--py311-plus` for `asyncio.TimeoutError` ```diff def throw(a): if a: - raise asyncio.TimeoutError('boom') + raise TimeoutError('boom') else: - raise socket.timeout('boom') + raise TimeoutError('boom') def catch(a): try: throw(a) - except (asyncio.TimeoutError, socket.timeout): + except TimeoutError: handle_error() ``` ### `typing.Text` str alias ```diff -def f(x: Text) -> None: +def f(x: str) -> None: ... ``` ### Unpacking list comprehensions ```diff -foo, bar, baz = [fn(x) for x in items] +foo, bar, baz = (fn(x) for x in items) ``` ### Rewrite `xml.etree.cElementTree` to `xml.etree.ElementTree` ```diff -import xml.etree.cElementTree as ET +import xml.etree.ElementTree as ET -from xml.etree.cElementTree import XML +from xml.etree.ElementTree import XML ``` ### Rewrite `type` of primitive ```diff -type('') +str -type(b'') +bytes -type(0) +int -type(0.) +float ``` ### `typing.NamedTuple` / `typing.TypedDict` py36+ syntax Availability: - `--py36-plus` is passed on the commandline. ```diff -NT = typing.NamedTuple('NT', [('a', int), ('b', Tuple[str, ...])]) +class NT(typing.NamedTuple): + a: int + b: Tuple[str, ...] -D1 = typing.TypedDict('D1', a=int, b=str) +class D1(typing.TypedDict): + a: int + b: str -D2 = typing.TypedDict('D2', {'a': int, 'b': str}) +class D2(typing.TypedDict): + a: int + b: str ``` ### f-strings Availability: - `--py36-plus` is passed on the commandline. ```diff -'{foo} {bar}'.format(foo=foo, bar=bar) +f'{foo} {bar}' -'{} {}'.format(foo, bar) +f'{foo} {bar}' -'{} {}'.format(foo.bar, baz.womp) +f'{foo.bar} {baz.womp}' -'{} {}'.format(f(), g()) +f'{f()} {g()}' -'{x}'.format(**locals()) +f'{x}' ``` _note_: `pyupgrade` is intentionally timid and will not create an f-string if it would make the expression longer or if the substitution parameters are sufficiently complicated (as this can decrease readability). ### `subprocess.run`: replace `universal_newlines` with `text` Availability: - `--py37-plus` is passed on the commandline. ```diff -output = subprocess.run(['foo'], universal_newlines=True) +output = subprocess.run(['foo'], text=True) ``` ### `subprocess.run`: replace `stdout=subprocess.PIPE, stderr=subprocess.PIPE` with
