Result = []

length = len(result_ip) # CALULATES LENGTH OF MENTIONED LIST

i = 0


while i < length: # LOOPS UNTIL ALL THE POSITIONS ARE DONW
    for lines in result_ip:
        for k in range(length): # HERE STARTS THE STATUS BAR

            try:
                (name, _, ip_address_list) = socket.gethostbyaddr(result_ip[i]) #RETRIEVES DNS USING IP ON THE LIST

            except socket.herror as msg: #ERROR HANDLER
                Result.append("nDNS NOT FOUND" + " - " + result_ip[i]+"n")
                i += 1
            else:
                ip_address1 = ip_address_list[0] #PROCESS THE DATA AND ADDS IT TO A NEW LIST
                Result.append(name + " - " + ip_address1+"n")
                i += 1 #ITERATES ADDING 1 TO i

            j = (k + 1) / length
            sys.stdout.write('r')

            ######### I THINK THE ISSUE IS HERE

            sys.stdout.write("[{:{}}] {:.1f}%".format("=" * k, length - 1, (100 / (length - 1) * k)))
            sys.stdout.flush()
            sleep(0.25)
