How do you read from stdin in python from a pipe which has no ending

Question

I\'ve problem to read from Standard input or pipe in python when the pipe is from a \"open\" (do not know right name) file.

I have as example pipetest.py:

while sys.stdin is a file-like object, meaning you can iterate over its lines, it will block until a EOF is inserted.

The behaviour can be described with the following pseudo-code:

while True:
    input = ""
    c = stdin.read(1)
    while c is not EOF:
        input += c
        c = stdin.read(1)
    for line in input.split('\n'):
        yield line

this means that, while you can iterate over sys.stdin's lines, you cannot use this approach for the task at hand and you must explicitly call read() or readline()
