Python 2.5.2-什么是代替'with'语句 [英] Python 2.5.2- what was instead of 'with' statement

问题描述

我为python 2.7编写了代码，但是服务器有2.5.我该如何重写下一个代码，使其在python 2.5.2中运行:

I wrote my code for python 2.7 but the server has 2.5. How do i rewrite the next code so it will run in python 2.5.2:

gzipHandler = gzip.open(gzipFile)

try:
    with open(txtFile, 'w') as out:
        for line in gzipHandler:
            out.write(line)
except: 
    pass

现在，当我尝试运行脚本时，出现此错误:

Right now, when i try to run my script I get this error:

警告:"with"将成为Python 2.6 Traceback中的保留关键字 (最近一次通话最近):文件"Main.py"，第7行，在 从Extractor导入Extractor文件"/data/client/scripts/Extractor.py"，第29行 与open(self._logFile，'w')一样: ^ SyntaxError:语法无效

Warning: 'with' will become a reserved keyword in Python 2.6 Traceback (most recent call last): File "Main.py", line 7, in from Extractor import Extractor File "/data/client/scripts/Extractor.py", line 29 with open(self._logFile, 'w') as out: ^ SyntaxError: invalid syntax

谢谢， 罗恩.

推荐答案

在Python 2.5中，您实际上可以使用with语句-只需从__future__导入即可:

In Python 2.5, you actually can use the with statement -- just import it from __future__:

from __future__ import with_statement
