Re: [Tutor] Removing Unnecessary Indentation and other problems
Including tutor list.
Please use ReplyAll when responding to the list.
Sorry about that. I am new to this so I didnt know I have to be very specific
towards every detailIt depends on what you are asking, but in this case
different downloads include different packages
so we need to know which OS, which version and which web site you got it from.
In this case I'll
assume you got it from the python.org site?
. I downloaded 'Python 3.3.2 Windows x86 MSI Installer (Windows binary -- does
not include source)' Thats fine it does have Tkinter included. Personally, for
Windows users I recommend
getting the Activestate.com version of Python instead. It includes some nice
extra features
and it integrates Python more closely with the Windows environment. But thats
not the
cause of your problem here.
from Tkinter import *
This is the problem. In Python v3 they changed the name of the Tkinter module
from
Tkinter to tkinter(no caps). I think it was just to make the name more
consistent with
other modules... The result is you need to change your import to be
from tkinter import *
For the second part of the question.. I don't know which font I am using but I
think its default font? OK, So in that case how are you running the program?
Are you using IDLE or a CMD shell window?
Or something else? One of the problems of using tabs, and of printing directly
in general, is that the
program may be displaying in many different environments and therefore with
different fonts.
You therefore have limited control over the output. That's why generating an
HTML page which
can have font information embedded into it and use tables etc to control layout
is a more reliable
option if you need precise control of layout.
If precise control is not so necessary and you think the font will be
monospaced then you can
do some things in a print statement that will help, just be aware that it may
not be 100% effective.
while sMainContinue == yor sMainContinue ==yes or sMainContinue ==YESor
sMainContinue ==Y:
userMainInput = (input(Please select one option from menu: ))
You are making this hard for yourself./ Its usually better to convert the
input to lowercase
(or uppercase if you prefer!) and then compare. So your line above could be:
while sMainContinue.lower() in ('y','yes'):
Also in the input() line you don't need the outer set of parens. But see
below...
#Robust Options: if input is a letter
if userMainInput.isdigit():
userInput = int(userMainInput)Again its more common in Python to just
do the conversion at the input stage and catch an
exception if the data is bad., so that would look like
try:
userInput = int( input(Please select one option from menu: ) )
except ValueError:
# deal with non numeric input here
#Options1
if userInput == 1:
print(\nRoad Information**)
print(Road Name,Speed,sep = \t\t)
for key,value in Dic.items():
print(key,value,sep = \t\t)And here is the display part and
it relies on tabs. Tabs work on fixed column positions so to be
consistent you would need to check the length of the strings and insert the
correct number of tabs
depending on whether the string was shorter or longer. In your case it could be
anywhere from
1 tab to 3 tabs... That's messy and using tabs for formatting like that is not
recommended.
Instead Python offers a formatting mechanism that you can apply to a string
before it is
printed which gives you much more control over spacing and justification etc.
You could read about it in the official docs but there is a more accessible
tutorial here:
http://infohost.nmt.edu/tcc/help/pubs/python/web/new-str-format.html
The key is to use fixed length string fields to output your data.
You may optionally choose to left justify the name and right justify the
speeds,
or you could just left justify everything. The choice is yours.
But remember format() still relies on the user having monospaced fonts for it
to work properly.
HTH,

Hi Sourav, Please use Reply all when you reply an email so that everyone else also gets your messages and your chances of getting better help increases.

The ultimate goal is work with OpenStack API. Can you please let me know, how to start on this. Thanks for the reply and thanks in advance. Sorry, I certainly didn't mean that your question was not good. Now that you have mentioned what specifically you are looking to learn, it becomes slightly easier to make some suggestions. I don't have any personal experience with OpenStack API. However, looking at [1], it seems like you will be mostly dealing with making HTTP requests and reading responses. There are couple of standard library modules such as urlllib2 and httplib that may be useful to you. However, in this case, you would certainly benefit from directly learning to use Requests [2]. Note that however, you will need to be familiar with Python data structures such as dictionaries and know how to work with JSON data ( please see the 'json' standard module). [1] http://docs.openstack.org/api/quick-start/content/ [2]http://www.python-requests.org/en/latest/ I am hoping those prove helpful.

So you have pass an arguments while you're calling it.
