python - removing iterated string from string array -

i writing small script lists connected hard disks on machine. need disk identifier(disk0), not partition id(disk0s1, disk0s2, etc.) how can iterate through array contains diskid , partitionid , remove partitionid entries? here's i'm trying far:

    import os      alldrives = os.listdir("/dev/")     parseddrives = []      def parsealldrives():         parseddrives = []         matching = []         drivename in alldrives:             if 'disk' in drivename:                 parseddrives.append(drivename)             else:                 continue         itemname in parseddrives:             if len(parseddrives) != 0:                 if 'rdisk' in itemname:                     parseddrives.remove(itemname)                 else:                     continue             else:                 continue  #### problem starts: #####          # iterate through possible partition identifiers         in range(5):             #create string partitionid             systempostfix = 's' + str(i)             matching.append(filter(lambda x: systempostfix in x, parseddrives))          match in matching:             if match in parseddrives:                 parseddrives.remove(match)                 print("found mactch , removed it")          print("matched: %s" % matching)         print(parseddrives)      parsealldrives() 

that last bit recent thing i've tried. open going different route.

try beginning with

alldrives = os.listdir("/dev/") disks = [drive drive in alldrives if ('disk' in drive)] 

then, given disks id's 5-chars length

short_disks = [disk[:6] disk in disks] unique_short_disks = list(set(short_disks))
