UNIX command to select the best edge values from a network file

I have a tab-delimited data representing network data (undirected). Among the duplicated edges, I wanted to select those edges for which I have the higher absolute value of the log values.
I have written a code in python, but its taking a lot of time. I would be grateful if someone helps me with an awk command. Kindly note, the network is undirected, i.e. A--B and B--A are duplicate edges. My original file has a large number of columns, I have given a simplified test data

Test data



Code:
     Gene1    Gene2    Log
    AT1G01020    AT1G01010    1.682708
    AT1G01020    AT1G01010    -1.90043
    AT1G01020    AT1G01010    -1.832192
    AT1G01070    AT1G01060    -0.591932
    AT1G01070    AT1G01060    -1.204241
    AT1G01073    AT1G01070    0.790549
    AT1G01060    AT1G01070    1.214972

Expected Output

Code:
    AT1G01020    AT1G01010    -1.90043
    AT1G01070    AT1G01060    1.214972
    AT1G01073    AT1G01070    0.790549

Code:
gene_table=file1.readlines() # In the real file, j[12]=Gene1, j[13]=Gene2 and j[27]=log value
lfc=[]
for j in gene_table:
    j=j.split("\t")
    j[12]=j[12].strip()
    j[13]=j[13].strip()
    lfc=[]
    int_list=[]
    lfc.append(float(j[27]))
    int_list.append(j[0])
    dict_int={}
    for k in gene_table:
        k=k.split("\t")
        k[12]=k[12].strip()
        k[13]=k[13].strip()
        if (j[0]!=k[0]) and ((j[12]==k[12] and j[13]==k[13]) or (j[12]==k[13] and j[12]==k[13])):
            lfc.append(float(k[27]))
    dict_int=dict(zip(int_list, lfc))
    x=max(lfc, key=abs)
    #print x
    listOfKeys = [key  for (key, value) in dict_int.items() if value == x]
    print listOfKeys

UPDATE-PYTHON-MODULES(8)				      System Manager's Manual					  UPDATE-PYTHON-MODULES(8)

NAME
update-python-modules - byte-compile python modules SYNOPSIS
update-python-modules [options] [package.public [...]] DESCRIPTION
The update-python-modules command is part of the python-support bundle. update-python-modules is responsible for the byte-compilation of python modules. When used in byte-compilation mode, it will byte-compile modules references in the files given on the command line. When used in installation mode, it will byte-compile them once for each installed python version, and will make them available for all of them. At each invocation, with or without arguments, update-python-modules will check for installed python versions, and will build or remove modules according to new or removed versions since the last time it was run. ARGUMENTS
Arguments must be files or directories located in the /usr/share/python-support directory. Depending on their extension, they are treated differently. package.public A file listing public modules to install for each version. These modules must lie in /usr/share/pyshared or /usr/lib/pyshared. package.private A file listing private modules to byte-compile for one Python version. package/ A legacy directory hierarchy of public modules. The C extensions and portions that change with the Python version are to be found in /usr/lib/python-support/pythonX.Y/package/. package.dirs A legacy file listing directories where to find private modules. OPTIONS
-h, --help Show summary of options. -v, --verbose Detail all actions while they are performed. -b, --bytecompile Only accept to work on private modules. When given this option, update-python-modules will fail if passed references to public mod- ules. -i, --install Only accept to work on public modules. When given this option, update-python-modules will fail if passed references to public mod- ules. -c, --clean Clean modules instead of installing them. -a, --rebuild-all Rebuild all private modules. This is necessary when the default python version was changed, for example. -f, --force-rebuild-all Clean all modules (public and private), and rebuild them. FILES
/usr/lib/pymodules/pythonX.Y/ These directories contain the byte-compiled modules for version pythonX.Y. SEE ALSO
