我有一个用python2编写的旧文件,其中包含了类似于148191387849281587952L的内容。当我试图(使用)在python3中阅读它时,我自然会得到SyntaxError: invalid syntax。PS。我目前看到的唯一解决方案需要修改文件: 转换为JSON:将文件读入python2,使用json编写它,然后使用json将其读入python3。使用L删除违规 浏览0提问于2018-07...
For conversions from Python 3 code to Py2/3, use thepasteurizescript instead. This converts Py3-only constructs (e.g. new metaclass syntax) to Py2/3 compatible constructs and adds__future__andfutureimports to the top of each module. ...

import py3to2 2. this will give u a compiler 'py3to2.compile_py3k' (similar to __builtin__.compile) 3. type help(compile) for help info example demonstrating pep3132 extended unpacking syntax: a,b,*c = 1,2,3,4 Python 2.5.2 (r252:60911, Jun 27 2008, 21:19:51) [GCC 3.4.6...
No more'<int:user_id>'ad-hoc syntax, and the ability to use any type/constructor (likeDecimal) inside your routes without having to define your own converter. Something like thishas already been implemented, and what you see is valid Python syntax, exploiting the new annotations to make it...
In addition to the 2to3 tool that allows 3.x code to be generated from 2.x source code, there's also the3to2tool, which aims to convert 3.x code back to 2.x code. In theory, this should work even better than going the other direction, since 3.x doesn't have as many nasty co...
- bpo-25019: Fixed a crash caused by setting non-string key of expat parser. Based on patch by John Leitch. - bpo-16180: Exit pdb if file has syntax error, instead of trapping user in an infinite loop. Patch by Xavier de Gaye. - bpo-24891: Fix a race condition at Python startup...
This converts Py3-only constructs (e.g. new metaclass syntax) to Py2/3 compatible constructs and adds __future__ and future imports to the top of each module.In both cases, the result should be relatively clean Py3-style code that runs mostly unchanged on both Python 2 and Python 3....
