How come my class is behaving like a static class?
<p>i have a module (a single .py file, actually), with a class called HashedDir.</p>

<p>when i import the file and instanciate 2 instances of that class, when i check the object's fields they're always the same, even if the two objects should be different.</p>

<p>Eg:</p>

<pre><code> h1 = HashedDir('/path/to/dir')
 print h1.getList()['files'] # /path/to/dir
 h2 = HashedDir('some/other/path')
 print h1.getList()['files'] # some/other/path
 print h2.getList()['files'] # some/other/path
</code></pre>

<p>Any idea?</p>

<p>This is the class:</p>

<pre><code>from os  import walk
from os import path
from hashlib import md5
import re

class HashedDir:
    """
    A list of files with associated md5 hashes generated retrieving thou
    a recursive walk in the directory tree starting from a provided root
    directory. Also stores the dirs in each dir
    """

    #    ('/path/to/dir/file3', '52bc309e11259af15e4623c7a0abc28c')
    #   ],
    #   'dirs': ['/path/to/dir1', '/path/to/dir2']
    #  }
    fileList = {'files': [], 'dirs': []}
    ignoreList = []

    def __init__(self, rootDir, ignoreList=[]):
        """

        that regular expression, don't count it
        """
        self.ignoreList = ignoreList

        for dirpath, dirnames, filenames in walk(rootDir):
            for fileName in filenames:
                completeName = path.join(dirpath,fileName)
                hash = md5(open(completeName).read()).hexdigest()
                relativePath = self._relativePath(completeName, rootDir)
                if not self._toBeIgnored(relativePath):
                    self.fileList['files'].append((relativePath, hash))
            for dirName in dirnames:
                completeName = path.join(dirpath, dirName)
                relativePath = self._relativePath(completeName, rootDir)
                if not self._toBeIgnored(relativePath):
                    self.fileList['dirs'].append(relativePath)

    def _relativePath(self, path, base):
        return path.replace(base, '')

    def _toBeIgnored(self, path):
        for regex in self.ignoreList:
            if re.compile(regex).search(path) != None:
                return True
        return False

    def getList(self):
        return self.fileList

<p>Thanks in advance</p>
