Wing IDE keygen

I have quite reverse engineering background but I have never tried to disassemble python bytecode. But i found it not so hard. Anyway i disassembled some files of Wing IDE to prepare this keygen. Here it is..

#!/usr/bin/python
def keygen(os,requestHash,version):
    _os,v29,v28,v27,v26 = os,0,0,0,0

    if(os != 'windows'):
        if(os != 'macosx'):
            if(os != 'linux'):
                if(version == '2'):
                    v6,v5,v24,v25 = 123,202,97,211
                elif(version == '3'):
                    v6,v5,v24,v25 = 127,45,209,198
        else:#linux
                if(version == '2'):
                    v6,v5,v24,v25 = 48,104,234,247
