*Memo for a string, bytes and bytearray:
str.splitlines() and bytes.splitlines() or bytearray.splitlines() can split a string and bytes or bytearray respectively at one or more line boundaries as shown below:
*Memo:
- The 1st argument is
keepends(Optional-Default:False-Type:bool):- If
keependsisTrue, one or more line boundaries are included otherwise they aren't included.
- If
- These below are line boundaries:
