Python：使用字典进行文件搜索

Question

I have written a small script to find a file in directories and sub-directories. I placed these in dictionaries and sub dictionaries within the root dictionary.

So I am trying to find a file within the dictionary of files and sub directories. I am trying to print out contents of this dictionary first then I will be able to modify the code to look for the file within the dictionary.

Here is the code:

def recurdd(db):
    for key in db:
        for item in db[key]:
            if hasattr(item,'append'):
                recurdd(item)
            else:
                print key,'=>',db[key]
                print

This code prints out the same dictionary all the time which I want to correct. So if I have a dictionary, ie:

d = {'a': [{'b': [1, 2, 3]}, {'c': [55, 12, 32]}, 1, 2]}

Please assist me with this issue.

Thanks

The correct code would be:

def recurse_directory(dictionary):
    for dirname, dir_content in dictionary.iteritems():
        for filename in dir_content:
            if type(filename) == dict: # It's a directory
                recurse_directory(filename)
            else:
                print "{} => {}".format(dirname, filename)
