some qustion about extract mitdb

[undefined0821]

hello,I'm trying to use python-wfdb instead of the wfdb package to run my code, but the “split” in this code doesn't work for wfdb.

"wfdb.rdann" returns an object instead of a string. So I'm wondering what the contents of labels _l(0) l(1) (2)(6) were when you wrote the original code?
