    <p>Sorry for the double post, I will update this question if I can't get things to work :)</p> <p>I am trying to compare two files. I will list the two file content:</p> <pre><code> File 1 File 2 "d.complex.1" "d.complex.1" 1 4 5 5 48 47 65 21 d.complex.10 d.complex.10 46 6 21 46 109 121 192 192 </code></pre> <p>TI am trying to compare the contents of the two file but not in a trivial way. I will explain what I want with an example. If you observe the file content I have typed above, the d.complex.1 of file_1 has "5" similar to d.complex.1 in file_2; the same d.complex.1 in file_1 has nothing similar to d.complex.10 in file_2. What I am trying to do is just to print out those d.complex. which has nothing in similar with the other d.complex. Consider the d.complex. as a heading if you want. But all I am trying is compare the numbers below each d.complex. and if nothing matches, I want that particular d.complex. from both files to be printed. If even one number is present in both d.complex. of both files, I want it to be rejected.</p> <p>My Code: The method I chose to achieve this was to use sets and then do a difference. Code I wrote was:</p> <pre><code>first_complex=open( "file1.txt", "r" ) first_complex_lines=first_complex.readlines() first_complex_lines=map( string.strip, first_complex_lines ) first_complex.close() second_complex=open( "file2.txt", "r" ) second_complex_lines=second_complex.readlines() second_complex_lines=map( string.strip, second_complex_lines ) second_complex.close() list_1=[] list_2=[] res_1=[] for line in first_complex_lines: if line.startswith( "d.complex" ): res_1.append( [] ) res_1[-1].append( line ) res_2=[] for line in second_complex_lines: if line.startswith( "d.complex" ): res_2.append( [] ) res_2[-1].append( line ) h=len( res_1 ) k=len( res_2 ) for i in res_1: for j in res_2: print i[0] print j[0] target_set=set ( i ) target_set_1=set( j ) for s in target_set: if s not in target_set_1: if s[0] != "d": print s </code></pre> <p>The above code is giving an output like this (just an example): d.complex.1.dssp d.complex.1.dssp 1 48 65</p> <pre><code>d.complex.1.dssp d.complex.10.dssp 46 21 </code></pre> <p>109</p> <p>What I would like to have is:</p> <pre><code>d.complex.1 d.complex.1 (name from file2) d.complex.1 d.complex.10 (name from file2) </code></pre> <p>I am sorry for confusing you guys, but this is all that is required.</p> <p>I am so new to python so my concept above might be flawed. Also I have never used sets before :(. Can someone give me a hand here?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
