md5 module error
提问by eozzy
I'm using an older version of PLY that uses the md5 module (among others):
我使用的是旧版本的 PLY，它使用 md5 模块（以及其他）：
import re, types, sys, cStringIO, md5, os.path
... although the script runs but not without this error:
...虽然脚本运行但并非没有此错误：
DeprecationWarning: the md5 module is deprecated; use hashlib instead
How do I fix it so the error goes away?
如何修复它以便错误消失？
Thanks
谢谢

I think the warning message is quite straightforward. You need to:
我认为警告信息非常简单。你需要：
from hashlib import md5
or you can use python < 2.5, http://docs.python.org/library/md5.html
或者你可以使用 python < 2.5，http://docs.python.org/library/md5.html

As mentioned, the warning can be silenced. And hashlib.md5(my_string) should do the same as md5.md5(my_string).
如前所述，警告可以被静音。hashlib.md5(my_string) 应该和 md5.md5(my_string) 一样。
>>> import md5
__main__:1: DeprecationWarning: the md5 module is deprecated; use hashlib instead
>>> import hashlib
>>> s = 'abc'
>>> m = md5.new(s)
>>> print s, m.hexdigest()
abc 900150983cd24fb0d6963f7d28e17f72
>>> m = hashlib.md5(s)
>>> print s, m.hexdigest()
abc 900150983cd24fb0d6963f7d28e17f72
>>> md5(s)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'module' object is not callable
>>> md5.md5(s)
<md5 HASH object @ 0x100493260>
>>> m = md5.md5(s)
>>> print s, m.hexdigest()
abc 900150983cd24fb0d6963f7d28e17f72
As @Dyno Fu says: you may need to track down what your code actually calls from md5.
正如@Dyno Fu 所说：您可能需要追踪您的代码实际从 md5 调用的内容。

i think the warning is ok,still you can use the md5 module,or else hashlib module contains md5 class
我认为警告没问题，您仍然可以使用 md5 模块，否则 hashlib 模块包含 md5 类
import hashlib
a=hashlib.md5("foo")
print a.hexdigest()
this would print the md5 checksum of the string "foo"
这将打印字符串“foo”的 md5 校验和

What about something like this?
像这样的事情怎么办？
try:
import warnings
warnings.catch_warnings()
warnings.simplefilter("ignore")
import md5
except ImportError as imp_err:
raise type(imp_err), type(imp_err)("{0}{1}".format(
imp_err.message,"Custom import message"))
