Exact match in strings in python

I am trying to find a sub-string in a string, but I am not achieving the results I want.

I have several strings that contains the direction to different directories: 

'/Users/mymac/Desktop/test_python/result_files_Sample_8_11/logs', 
'/Users/mymac/Desktop/test_python/result_files_Sample_8_1/logs', 
'/Users/mymac/Desktop/test_python/result_files_Sample_8_9/logs'

Here is the part of my code here I am trying to find the exact match to the sub-string:

 for name in sample_names:

        if (dire.find(name)!=-1): 

            for files in os.walk(dire):

                for file in files:
                    list_files=[]
                    list_files.append(file)
                    file_dict[name]=list_files

Everything works fine except that when it looks for Sample_8_1 in the string that contains the directory, the if condition also accepts the name Sample_8_11. How can I make it so that it makes an exact match to prevent from entering the same directory more than once?

Assuming that dire is populated with absolute path names

for name in sample_names:
    if name in dire:
        ...

e.g. 

samples = ['/home/msvalkon/work/tmp_1',
           '/home/msvalkon/work/tmp_11']

dirs = ['/home/msvalkon/work/tmp_11']

for name in samples:
    if name in dirs:
        print "Entry %s matches" % name

Entry /home/msvalkon/work/tmp_11 matches

You could try searching for sample_8_1/ (i.e., include the following slash). I guess given your code that would be dire.find(name+'/'). This just a quick and dirty approach.
