How can make text output easy and shortly?

I want modify some text file. But My script too long.

How can make short? who can advise about my script.

I want made loop acap = line[4] ucap = line[5] ucp = line[6] saved = line[8] value like tcap.

below is my script.

with open("find_c_volume_show.txt", "r") as f:
        for line in f:
                if "%" in line:
                        line = line.split(',')
                        vser = line[0]
                        vol = line[1]
                        aggr = line[2]
                        node = line[7]

                        if 'TB' in line[3]:
                                tcap = str(line[3].split("TB")[0])
                                tcap = float(tcap) if '.' in tcap else int(tcap)
                        elif 'GB' in line[3]:
                                tcap = str(line[3].split("GB")[0])
                                tcap = (float(tcap) if '.' in tcap else int(tcap) /1024)
                        elif 'MB' in line[3]:
                                tcap = str(line[3].split("MB")[0])
                                tcap = (float(tcap) if '.' in tcap else int(tcap) /1024 /1024)
                        elif 'KB' in line[3]:
                                tcap = str(line[3].split("KB")[0])
                                tcap = (float(tcap) if '.' in tcap else int(tcap) /1024 /1024 /1024)
                        elif 'B' in line[3]:
                                tcap = str(line[3].split("B")[0])
                                tcap = (float(tcap) if '.' in tcap else int(tcap) /1024 /1024 /1024 /1024)
                        else:
                                print ("Please check script.")

                        if 'TB' in line[4]:
                                acap = str(line[4].split("TB")[0])
                                acap = float(acap) if '.' in acap else int(tcap)
                        elif 'GB' in line[4]:
                                acap = str(line[4].split("GB")[0])
                                acap = (float(acap) if '.' in acap else int(tcap) /1024)
                        elif 'MB' in line[4]:
                                acap = str(line[4].split("MB")[0])
                                acap = (float(acap) if '.' in acap else int(tcap) /1024 /1024)
                        elif 'KB' in line[4]:
                                acap = str(line[4].split("KB")[0])
                                acap = (float(acap) if '.' in acap else int(tcap) /1024 /1024 /1024)
                        elif 'B' in line[4]:
                                acap = str(line[4].split("B")[0])
                                acap = (float(acap) if '.' in acap else int(tcap) /1024 /1024 /1024 /1024)
                        else:
                                print ("Please check script.")

                        if 'TB' in line[5]:
                                ucap = str(line[5].split("TB")[0])
                        .....

                        if 'TB' in line[6]:
                                ucp = str(line[6].split("TB")[0])

                        .....

                        if 'TB' in line[8]:
                                saved = str(line[8].split("TB")[0])

                        .....
                        line = vser, vol, aggr, tcap, acap, ucap, ucp, saved
                print (line)

I want match to TB capacity format in text. below is my text file.
