I keep getting an error line 14 needing to be unicode.

when ever I wrap the line iwith the atttrbute .decode('utf-8') i get the error that the function doesn't have that attribute.

I was working with asda earlier today and I got most of the errors fixed, this is the alst one i am having an issue getting past.

Guest65574: I think your problem on line 14 is that you have unicode, and need to have bytes

So on line 14 when i try to write.

Guest65574: generally data that's being transmitted over the network needs to be in bytes, so when you receive data you have to decode from bytes→unicode, and when you send data you first encode it from unicode→bytes

Guest65574: so try self.transport.write(self.getQuote().encode("utf-8")) # note "encode", not "decode"

File "C:/Users/Twisted/quoteserver.py", line 14, in dataReceived self.transport.write(self.getQuote().encode("utf-8")) builtins.AttributeError: 'bytes' object has no attribute 'encode'

@Guest65574

this is the error i get when i try that.

Guest65574: well, I'm confused. that's saying that self.getQuote() is returning a 'bytes' object. Which it definitely isn't in the code you pastebinned. On the other hand, if it *is* somehow returning a 'bytes' object, then self.transport.write(self.getQuote()) should have worked, and your complaint was that it didn't. So not sure what's going on :-)

hmmm okay.

idk if that is saying that it is returning a bytes object as mch as it might be saying it just doesn't have the ability to use teh function encode?

Guest65574: njs: I think it's because of the self.updateQuote(data) in dataRecieved()

EACFreddy: ah! so without the call to .encode(), it crashes the first time that it reaches line 14. With the call to .encode(), the first time it reaches line 14 it works, then it calls updateQuote(data), which replaces the saved quote with a bytes object, and then the *next* time it reaches line 14 it crashes because *now* getQuote() is returning bytes instead of a str

using a simple function like this can do the trick: ensure_bytes = lambda s: s if isinstance(s, bytes) else bytes(s, "utf-8")

Guest65574: the error "builtins.AttributeError: 'bytes' object has no attribute 'encode'" is Python telling you exactly that: (a) you tried to do 'someobj.encode', (b) this failed because 'someobj' didn't have an 'encode' attribute, (c) also by the way, 'someobj' was a 'bytes' object (which makes sense, since bytes objects never have an encode method)

EACFreddy: that's a terrible habit though :-(

interesting.

okay let me see i understand this right.

so in quote server my data is in byte?

where do i put the cod e you wrote?

EaC freddy?

if you want clean code, nowhere and instead make it a habit to only use bytes everywhere

How do i ensure I am using bytes?

b"something" instead of "something"

where would i put the b? The weird thing is that the program is printing what I want it to print. so idk the point of the error.

if you want clean code, make it a habit to decode text on input and encode it on output :-P

I FIXED IT Yay.

so I needed a "b" on line 30 in the quote factory class.

not in line 14.

can someone expalin to me why it was throwing out the error in such an odd place?

Looks like buildbot.twistedmatrix.com is down

I'm writing a small oneshot client which shall print its output to stdout. However the client use twisted.logger for its output. This is fine for the server, since it captures stdout, but for the client this isn't how I want this. How can I relate to the logger in a client application?

Can I configure twister.logger.Logger() not to capture stdout, so print could work as-is?
