[Tutor] Fw: URGENT: PYTHON QUESTION

2016-03-31 Thread accessmuah via Tutor 
Hi,
Pls, assist with this QuestionKindly stroll to the end
DS LABCreate a function manipulate_data that does the followingAccepts as the 
first parameter a string specifying the data structure to be used "list", "set" 
or "dictionary" Accepts as the second parameter the data to be manipulated 
based on the data structure specified e.g [1, 4, 9, 16, 25] for a list data 
structure Based off the first parameter   
   - return the reverse of a list or
   - add items `"ANDELA"`, `"TIA"` and `"AFRICA"` to the set and return the 
resulting set
   - return the keys of a dictionary


My Answer below - Kindly helped reviewed it
def manipulate_data(kind, data):     if kind == 'list':         return 
list(data)[::-1]     elif kind == 'set':         data=set({"a", "b", "c", "d", 
"e", "ANDELA", "TIA", "AFRICA"})        return set(data)     elif kind == 
'dictionary':         return dict.keys(data) manipulate_data("list", 
range(1,6)) manipulate_data("set", {"a", "b", "c", "d", "e", "ANDELA", "TIA", 
"AFRICA"})manipulate_data("dictionary", {"apples": 23, "oranges": 15, 
"mangoes": 3, "grapes": 45})

CODE RESULT


 But i cant proceed to next stage...see error below   Pls assist

Unfortunately your code has been mangled by the email. Can you try 
sending it again WITHOUT using Yahoo's "Rich Text" (HTML mail)?

I will try to reverse-engineer what you meant:

def manipulate_data(kind, data):
    if kind == 'list':
        return list(data)[::-1]
    elif kind == 'set':
        data=set({"a", "b", "c", "d", "e", "ANDELA", "TIA", "AFRICA"})
        return set(data)
elif kind == 'dictionary':
        return dict.keys(data) 

manipulate_data("list", range(1,6)) 
manipulate_data("set", {"a", "b", "c", "d", "e", "ANDELA", "TIA", "AFRICA"})
manipulate_data("dictionary", {"apples": 23, "oranges": 15, "mangoes": 3, 
"grapes": 45})


Is that what you intended?

I looked below, but you have not included the error. Perhaps you 
included it as an attachment? In that case, it would probably be 
deleted, and if it is a screen-shot, it will be useless to anyone who is 
blind or visually impaired and reading this using a screen reader.

Please COPY and PASTE the text of the error into your email.

That's interesting. I've used OpenGL on Windows and Linux but not on
OSX so I'm not sure exactly what you mean. Modern Linux desktops
(Unity, Gnome3, KDE4, etc.) use OpenGL-based compositing just like OSX
does and I'm fairly sure Android does as well. Does it just work out
better on OSX?

I know that work is under way to replace X itself with Wayland and
reimplement the core toolkits (Gtk, Qt, etc) on top of Wayland with
OpenGL as the core and without the vagaries of the X protocol and
without needing the DRI2 extension. Perhaps that would lead to the
sort of situation that there is on OSX...

I can't speak for Linux because, although it's my main platform
I've not done much graphics on it. But on Windows the core OS APIs
all use a device context or GDI object to do their painting. To
use OpenGL you need to bridge between the GDI of native windows
and the OpenGL libraries. If you want to draw a moving string for
instance you need to either use the Windows graphics system
or the OpenGL system. In MacOS X the ODS system is OpenGL so
you can use the native API interleaved with your OpenGL code.

That's news to me, I thought they(Linux) all worked through the
X layers (Xlib, Xt etc).

Yes, and at that point I'd expect Linux to be as seamless as MacOS.
But for now it seems to me that you still have to initialise libraries
and explicitly link your OpenGL objects to your OS (X)windows etc.
In short you have to tell the OS GUI that you are choosing to render
on OpenGL and/or use the OpenGL library routines to do any drawing.
It's a one or the other approach.

In MacOS it's (almost) a mix n match approach, you can use whichever
API call is easier for you, OS or OpenGL native and interleave them.
There are some issues that arise but I don't do enough graphics
work to fully understand them! For my simple needs it all pretty
much just worked.

PS.
When I write MacOS above I suspect I should really be saying
Cocoa, but I'm, not even expert enough in MacOSX to be sure of
that! :-)

elif kind == 'set':
#data=set({"a", "b", "c", "d", "e", "ANDELA", "TIA", "AFRICA"})

return dict.keys(data)
