In the Python.org 3.1 documentation (section 20.4.6), there is a
simple “Hello World” WSGI application which includes the following
method...
def hello_world_app(environ, start_response):
status ='200 OK' # HTTP Status
headers =(b'Content-type', b'text/plain; charset=utf-8')] # HTTP Headers
start_response(status, headers)
# The returned object is going to be printed
return [b"Hello World"]
Question - Can anyone tell me why the 'b' prefix is present before
each string? The method seems to work equally well with and without
the prefix. From what I can gather from the documentation the b
prefix represents a bytes literal, but can anyone explain (in simple
english) what this means?
Many thanks,
Alan
