Please help me in debugging this python code

Question

This is a program that finds anagrams for words greater than 15 letters.There's no syntax error but the output is not as expected.I will be extremely grateful if u could point out the logical error in the program. I downloaded the word list from http://thinkpython.com/code/words.txt PS-I am new to Python.If there's a better approach please tell me....

def anagrams():
    fin1=open('words.txt')
    val=-1
    fin2=open('dic.txt')
    for i in range(100000):
        fin2.seek(0)              
        word1=fin1.readline()
        if len(word1)>18:               
            for j in range(100000):
                word2=fin2.readline()
                flag=1
                if len(word2)==len(word1)and word1!=word2:

                    for k in range(len(word1)-1):
                        if word1.find(word2[k])==-1:
                            flag=1
                            break
                        else:
                            flag=0
                if flag==0:
                    print word2,'is anagram of ',word1,'\n'

Answer 1

Not related to the code you've posted, but you can do this using simple Counter objects, which will maintain the Count of all the characters for you.

>>> from collections import Counter
>>> def is_anagram(string1, string2):
...     return Counter(string1) == Counter(string2)
... 
>>> is_anagram("anagram anagram", "gramana anagram")
True

Answer 2

One problem I see is that if both words have the same letters but in different amounts, you will claim they are anagrams when they are not.

Some improvements:

• To see if two words are anagrams, sort the letters in each & compare (they should be the same) (or use Counter as suggested elsewhere)
• Your code will test each pair of words twice: (word1,word2) and later (word2,word1).
