As has been discussed before on this list, there is in 3.x.
https://docs.python.org/3/library/sys.html#sys.stdin
>>> b=sys.stdin.buffer.readline()
a line
>>> b
b'a line\r\n'
In other words, 3.x text mode (which essentially nothing to do with 2.x
'text' mode), is a wrapped binary mode that gives users the *choice* to
read bytes or text.
One can also convert a stream permanently with .detach()
>>> import sys
>>> sys.stdin = sys.stdin.detach()
>>> b = sys.stdin.readline()
a line
>>> b
b'a line\r\n'
This does diable the input() function ;-).
>>> b = input()
