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

问题

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?

回答1:

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']

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')
