Getting The Error: Expected String Or Bytes-like Object When Using Re Split Method

This is continuation from the following OP1. While the suggestion by @Rakesh is awesomely compact, but the same solution cannot function properly when used with an open file which

Solution 1:

Dirty workaround

Extract the binary and get the string

raw_hypno_single = [x for x in str(f.read()).split('Sleep stage',1)][1:]

Then, split the sleep stage and movement as suggested in OP1

  raw_hypno =re.split(r"Sleep stage|Movement time", raw_hypno_single[0])

The full code is

file= 'edfx\\SC4002EC-Hypnogram.edf'# Please change according to the location of you filewithopen(file, mode='rb') as f:  
  raw_hypno_single = [x for x instr(f.read()).split('Sleep stage',1)][1:]
  raw_hypno =re.split(r"Sleep stage|Movement time", raw_hypno_single[0])
