May I ask you to explain how to convert levels again?

write a text file like

1113
1111
1111
2111

put it in a file called level_0 and run

python levelconvert.py 0

?
If I do that, I get

$ python levelconvert.py 0
Traceback (most recent call last):
  File "levelconvert.py", line 29, in <module>
    data = data[1].split("=")[1].split("_")
IndexError: list index out of range
