[Tutor] question already discussed with oscar benjamin

[Linsey Raaijmakers]

Hi,

Im trying to work with the help Oscar provided me, but I still get stuck :(
So what I'm trying to do now is write the program with the following input
and output:

Input:
action,start,apex,stop
3, 12, 13, 15
4, 15, 15, 15
3, 20, 21, 25
5, 21, 23, 30
...

And when you run your program it prints out:
actions, start, stop
[3], 12, 13
[], 14,15
[4], 15, 15
[], 16, 19
[3], 20, 21
[3, 5], 21, 21
[5], 22, 23
...

I don't want to use the stop. Only the start till apex is important.

This is the code I have now:

now = onset_list[0]
end = apex_list[0]
active = action_list[0]

for i in range(1,len(onset_list)):
  next_start = onset_list[i]
  next_end = apex_list[i]
  next_active = action_list[i]
  prev_end = apex_list[i-1]

  while next_start > end:
    print active+"\t"+now+'\t'+end
    end = next_end
    now = next_start
    active = next_active
  print active+','+next_active+'\t'+now+'\t'+next_end

But my output will print now:

3    12    13
4,4  15    15
4     15    15
3,3   20    21
3,5   20    25

How do I fix that it doesn't print out the double ones?
I'm sorry that I can't figure it out without your help. Im really trying..
:(
