Change newline character .readline() seeks

input, python, readline

Solution

No.

Consider creating a generator using `file.read()` and yielding chunks delimited by given character.

Edit:

The sample you provided should work just fine. I would prefer to use a generator though:

def chunks(file, delim='\n'):
    buf = bytearray(), 
    while True:
        c = self.read(1)
        if c == '': return
        buf += c
        if c == delim: 
            yield str(buf)
            buf = bytearray()

Problem

Is it possible to change the newline character the `.readline()` method looks for while reading lines? I might have the need to read a stream from a file object that will be delimited in something other than newlines and it could be handy to get a chunk at a time. `file` objects don't have a `readuntil` which I wouldn't have to create if I can use `readline` EDIT: I haven't yet tried it on a pipe other than `stdin`; but this seems to work. ``` class cfile(file): def __init__(self, *args): file.__init__(self, *args) def readuntil(self, char): buf = bytearray() while True: rchar = self.read(1) buf += rchar if rchar == char: return str(buf) ``` usage: ``` >>> import test >>> tfile = test.cfile('/proc/self/fd/0', 'r') >>> tfile.readuntil('0') this line has no char zero this one doesn't either, this one does though, 0 "this line has no char zero\nthis one doesn't either,\nthis one does though, 0" >>> ```
