Jose,

You've had already very good advise; all I wanted to do is recommend the use of 
PyParsing (https://github.com/pyparsing/pyparsing).

It helped me a lot in creating and parsing a simple grammar I had to implement 
in a personal project. If you've ever used lex or yacc you'll appreciate 
PyParsing's simplicity. Of course, as with anything else; there is a (rather 
small) learning curve

The most common error I've seen while installing Pillow is due to the fact that 
you need to be able to compile part of its code and you might not have that 
privilege in your working environment.

However, that is just a wild guess and you do need to give us more information.

You might want to check this project: https://pybee.org/

I've never used it but it shows promising.

BTW, I'm a diabetic myself and I would be very thankful if you could share your 
application.

I'm currently using 2 Android apps:

StickBuddy offers a system to keep track of both where you pinch your fingers 
and where you inject insulin thus avoiding injecting or pinching repeatedly in 
the same locations. 

Insulator is a quick and dirty insuline intake calculator.

They are both great but I'd like to have them in a single app that would 
immediately calculate the insuline needed according to the reading I just enter.

StickBuddy has a lot of other interesting goodies; It also helps me keep track 
of my carbohydrate intake.

Both apps are free.

I have bought a few courses from udemy (https://www.udemy.com/) on different 
matters. They are not necessarily the best but for $10 a course you are really 
getting your money's worth and in my experience, some of these courses are a 
great start.

In reviewing this courses, those by Jose Portilla are the best. The guy is a 
python professional. Of course, there are others.

Once you get acquainted with the language and the community (which is not 
perfect but still the best I've ever found); you will be able to discern your 
next steps

Good luck!

P.D.: I have not relationship or connection to udemy, other than being a 
satisfied customer

And after you're done with the OFFICIAL tutorials; there thousands of excellent

If you're more of the 'visual' person, you can also find tutorials in youtube. 
http://udemy.com also offers many free courses.

Just my 2 cents:

import random

def rollDie(number):
rolls = {1:0, 2:0, 3:0, 4:0, 5:0, 6:0}
for i in range(0, number):
roll=int(random.randint(1,6))
rolls[roll] += 1
return rolls

if __name__ == "__main__":
rolls = rollDie(50)
most_rolled = rolls[max(rolls, key=lambda i: rolls[i])]
top_rollers = [k for k,v in rolls.items() if v == most_rolled]
print('The dice rolled: %s' % (rolls,))
if len(top_rollers) > 1:
message = 'The sides with most hits are %s, with %i hits each.'
else:
message = 'The side with most hits is %s, with %i hits'
print(message % (top_rollers, most_rolled))

# Sample output:
# The dice rolled: {1: 10, 2: 10, 3: 7, 4: 7, 5: 10, 6: 6}
# The sides with most hits are [1, 2, 5], with 10 hits each.

Python is very good at giving you a string representation of any object. 
However, such capabilities do fall short every now and then. That is why when 
defining your own classes, you must also override the __init__() and _-repr__() 
methods so you can get a better suited string representation of such objects.

"│": vertical_line, v_line

back in the days of CPM this group was referred to as "box characters", and 
each of them were called as follows:

"│": vertical_line, v_line

"├─": left_intersection, l_intersection, left_tee, l_tee

"└─": bottom_left_corner, bl_corner

No pun intended, but I hope you are not typing your code like you typed your

OTOH, python code is not supposed to be compiled.

Another tip: If you really are copying and pasting, I'd recommend you first 
paste the code to the text editor of your like and MAKE SURE YOU ARE NOT MIXING 
SPACES AND TAB CHARACTERS FOR INDENTATION PURPOSES.

Use either, or but do not mix them, specially not on the same line. IMHO, it is

Switch and case statements are such a waste of time that, in order to 
understand them you have to mentally use if/elseif/else/endif statements. 
Furthermore, the concepts of switch and case could not even exist without the 
notion of if/elseif/else/endif statements. Why then, add an extra level of 
complication??.

Go play with Java or Maybe C++. Have fun with their fancy if/elseif/else/endif 
statements oops, sorry, they call them switch and/or case statements.

Re: Pandas SQL Update

[Mario R. Osorio]

You are not specifying how are you doing the comparison, but here is my 2 cents:

Import the foxpro tables into the MySQL database and then you'll be able to do 
your update in a single SQL statement, which, even for that many records would 
take some only a few seconds, then delete th imported data.

Importing the foxpro tables into MySQL will take a little longer but I'm sure 
that, once automated, the whole process shouldn't take more than a couple of 
minutes.

have NEVER given you the stated output.

Most of us here are noobs and those that are not, were noobs once; so we all 
can deal with noobs, but none should have to deal with a***holes.

Need help with pushing technology ... and a bit more ...

[Mario R. Osorio]

Background:
===
We are studying the possibility of creating a system that will have the 
following entities:
Customer(s) (appCustomer)
Service Provider(s) (appProviders) and
Manager(s)
Server(s)

appCustomers will have all appServices available to them and appServices will 
have at least one appManager and zero to many appServers.

Each one of these entities will run an application on android, ios and windoze 
phone at least, as well as (hopefully) linux, osx and windoze (these last three 
are needed for appManagers)

An appCustomer will use either an application or a given web site to request 
services via HTTP from the available appProviders.

Our system should immediately upon receiving this order, notify all involved 
appManagers and appServers, report back to appCustomer  who got notified of 
his/her request.

appManagers and appServers will interact with the system via applications in 
order to notify appCustomer/appManager(s) of any progress in serving the 
appService, until its completion.

All notification must be logged so that anyone involved in a given appService 
can check all activity and, for example, to allow appManagers to supervise the 
completion of a given appService request.

Reading the previous explanation I notice this is pretty much your common 
“Purchase Order System” except we need real time, bullet proof communications 
between all players, along with the possibility of SMS and mail capabilities as 
well as logs for all communication media.

Our system is to go live immediately with one (paying) customer representing 
around 100 appCustomers. We are expecting the live system to produce anywhere 
between 500 to 2000 notifications per day which is not a lot but (expected) 
growth will be exponential and might reach about a million notifications in 
about a year or two.

Observations:
=
I'd like to keep this project python/C/C++ only, or at least as much as 
possible.
I'm not a seasoned python/C/C++ programmer though; but I'm in l.o.v.e. with 
python and C and C++.
I understand even less about communications and I know I have to use some way 
to push all notifications, but I have not been able to find a solution that 
will work on all needed platforms (android, ios, windows phone, linux, osx and 
windows). I wouldn't mind using two or three different push technologies if 
that was the case but: 

Questions:
==
Isn't there a better way to push notifications?
Do I forcibly have to use a service such as “Urban Airship”, “Pushwoosh”, 
“Amazon SNS”, “Windows Azure Notification Hubs”, “Pushover”, “Prowl” or “Notify 
My Android”??
Would it be possible to build our own push service by using a combination of 
telnet, xmlrpc, websockets or xmpp along with twisted, tornado or gevent; 
living along with django and possible mezzanine in my “perfect python world”?
Am I asking too much or am I so lost I don't even make sense?

I've been reading about all these topics/products in the las couple of days and 
every line I read seems to get me the more confused...

When I was initially involved in this idea I thought it was all about finding a 
nice library for a good real time communications protocol 
(https://groups.google.com/forum/#!topic/django-users/vZQ3C4DS73g) but, as I 
said before; I know nothing about communications and in spite of all the good 
intentions of those answering that post; I am yet to make sense of everything.

I do not ask for a solution to my situation but at least some light as to what 
might be a good path to follow … I will make sure you confess a solution once I 
figure out what are you talking about :)

I will really appreciate and and all comments, ideas and recommendations … even 
epithets!

Thanks a lot in advanced!
