Is it possible to place two separators in string split() method?

Sorry for the lack of better title.

Hopefully the explanation below help. Given the following string:

 f=' Sleep stage W\\x14\\x00+26070\\x1590\\x14 Sleep stage W\\x14\\x00+26070\\x1590\\x14 Movement time\\x14\\x00+28110\\x15120\\x14 Sleep stage  3\\x14\\x00+28230\\x1530\\x14'

and are to be split as below

' W\\x14\\x00+26070\\x1590\\x14 '
' W\\x14\\x00+26070\\x1590\\x14 '
' \\x14\\x00+28110\\x15120\\x14 '
'  3\\x14\\x00+28230\\x1530\\x14'

To realise this, the following code was drafted

f=' Sleep stage W\\x14\\x00+26070\\x1590\\x14 Sleep stage W\\x14\\x00+26070\\x1590\\x14 Movement time\\x14\\x00+28110\\x15120\\x14 Sleep stage  3\\x14\\x00+28230\\x1530\\x14'
raw_hypno = [x for x in f.split('Sleep stage')][1:]

which produce the following Output

' W\\x14\\x00+26070\\x1590\\x14 '
' W\\x14\\x00+26070\\x1590\\x14 Movement time\\x14\\x00+28110\\x15120\\x14 '
'  3\\x14\\x00+28230\\x1530\\x14'

As can be seen, the detail Movement time was not properly split.

May I know whether it is possible to assign two split condition using the split approach?

You can first replace all the 'Movement time' into 'Sleep stage',

then simply split by 'Sleep stage':

f=' Sleep stage W\\x14\\x00+26070\\x1590\\x14 Sleep stage W\\x14\\x00+26070\\x1590\\x14 Movement time\\x14\\x00+28110\\x15120\\x14 Sleep stage  3\\x14\\x00+28230\\x1530\\x14'.replace('Movement time','Sleep stage').split('Sleep stage')

Using Regex --> re.split.

Ex:

f=' Sleep stage W\\x14\\x00+26070\\x1590\\x14 Sleep stage W\\x14\\x00+26070\\x1590\\x14 Movement time\\x14\\x00+28110\\x15120\\x14 Sleep stage  3\\x14\\x00+28230\\x1530\\x14'
print(re.split(r"Sleep stage|Movement time", f))

Output:

[' ', ' W\\x14\\x00+26070\\x1590\\x14 ', ' W\\x14\\x00+26070\\x1590\\x14 ', '\\x14\\x00+28110\\x15120\\x14 ', '  3\\x14\\x00+28230\\x1530\\x14']
