How can I read a text file and save the numbers inside a group to a 5 different lists in python -

i have text file have structure:

 transactions/sec group = aa\code1\kb   100   200   300    400    500    transactions/sec group = ab\code2\kb    800    300    400    500    600    transactions/sec group = ac\code3\kb    400    300    500    600    700    transactions/sec group = ad\code4\kb    200    200    300    400    400 

i read each group , save 5 numbers in 5 different lists. example, read group 1, , create list 1, list 2, list 3, list 4, list 5. read group 2, , numbers list 2, "append" them in list 1, list 2, list 3, list 4, list 5...

this did:

with open('output.txt') foutput:      count = 0     list1 = []     list2 = []     list3 = []     list4 = []     list5 = []     line in foutput:         #print line         count = count + 1          if 'group' in line:                          key = line[line.index('=')+1:].strip()             #f.write(key)         else:                value = float(line.strip())              list1 = value                                                            ind += 1             list2 = float(line.strip() + '\n') 

the code not working, have 5 numbers in 1 list, , need each number in different lists....

it doesnt give me error having numbers in 1 list....(or in 1 variable, value variable)

thank help.

if can assume file constant format every time, can this. i'm going use dict instead of 5 lists, , use item after = key.

f = open("output.txt", "r") lines = [line.rstrip() line in f if line != "\n"] #get lines, strip newline chars, , remove lines newlines. lines.close()  num_lists = 5  groups = [[] in range(num_lists)]  listindex = 0  line in lines:     if "transactions/sec group" not in line:         groups[listindex].append(float(line))         listindex += 1         if listindex == num_lists:             listindex = 0
