ShellCon 2020
ShellCon 2020 takes place 9th – 10th October 2020
ShellCon is an information security conference that is held annually in the beautiful beach cities of Los Angeles. Our conference is a growing event that creates an atmosphere of open communication, collaboration, and connection. We value community, technical knowledge, and getting your hands dirty. Presentations and events at the con will have a focus on practicality and real-world applications. We want you to walk away from ShellCon with an itch to try what you just learned and the knowledge to do so
Royal Astronomical Society talks Aug 2020
I attended a really interesting talk on Searching for Earth 2.0 with the RAS last week.
A recording is up on their Youtube Channel.
They have a few other talks coming up that may be of interest:-
Tomorrow 26/8: Lockdown Learning: online preschool level space session
Thurdsay 27/8: RAS Quilt Project – Online Stitching Session

Virtual Code Club August 2020
The Paignton Library virtual code club is still running, please feel free to share what you are working on in Scratch with our Scratch studio
This is a newly created studio for these completed projects.
To keep people safe this studio is also invite only you will therefore need to contact the library, provide your scratch user name and I can invite you in.
Please contact [Paignton Library and information centre](https://www.torbaylibraries.org.uk/web/arena/paigntonlibrary
Related profiles :-
Both Repl.it and FreeCodeCamp have excellent features, to share code, ask for help and help others.
I have been looking in to the Repl.it teams feature at the moment, early days as I think I will wait till the forum feature is up as this seems integral to the teams feature.
Stay safe on the forums.
For advice on e-safety please see ThinkUKnow

Add more functions
I have added a few more maths functions to the application and also provided a clear function. There are still a few items to add to help improve debugging but the application is starting to take shape.
Notes
window = Tk()
window.title('Maths Application')
window.geometry("570x150") # w x h
window.resizable(0,0)
The above code is being modified as I go. So I am changing the window size depending on what is being displayed.
I have also made the Window title reflect the purpose of the application.
That the source code now has 'result' as a label rather than output. This will show up future screenshots.
The code for the above is as follows.
#!/usr/bin/env python
import Tkinter # note use of caps
from Tkinter import *
window = Tk()
window.title('Maths Application')
window.geometry("570x150") # w x h
window.resizable(0,0)
#define button actions
def btn1():
#convert box text in to integers
ent1 = int(entrytext.get())
ent2 = int(entrytext2.get())
#add the 2 integers and store in variable add
add = (ent1 + ent2)
print (add)
#insert value of variable add in to box outtext
outtext1.insert(0,str(add)) # insert response
def btn2():
#print("subtraction")
ent1 = int(entrytext.get())
ent2 = int(entrytext2.get())
#subtract the 2 integers and store in variable sub
sub = (ent1 - ent2)
#insert value of variable sub in to box outtext
outtext1.insert(0,str(sub)) # insert response
def btn3():
#print("multiply")
ent1 = int(entrytext.get())
ent2 = int(entrytext2.get())
#multiply the 2 integers and store in variable mul
mul = (ent1 * ent2)
#insert value of variable mul in to box outtext
outtext1.insert(0,str(mul)) # insert response
def btn4():
#print("divide")
ent1 = int(entrytext.get())
ent2 = int(entrytext2.get())
#multiply the 2 integers and store in variable div
div = (ent1 / ent2)
#insert value of variable mul in to box outtext
outtext1.insert(0,str(div)) # insert response
#clear boxes
def clear():
#print("clear boxes") # leave in for legacy testing
entrytext.delete(0, END) # clear input box
entrytext2.delete(0, END) # clear input box2
outtext1.delete(0, END) # clear output box
btn_tog2 = Button( window, text ='+', command=btn1) # add
btn_tog3 = Button( window, text ='-', command=btn2) # subtract
btn_tog4 = Button( window, text ='x', command=btn3) #multiply
btn_tog5 = Button( window, text ='/', command=btn4) #divide
btn_tog6 = Button( window, text ='Clear', command=clear) #clear
btn_exit = Button( window, text ='Exit',command=exit) #exit
# define some labels
box1 = Label(window, text="1st Value")
box2 = Label(window, text="2nd Value")
box3 = Label(window, text="Result")
#define entry box
entry1 = StringVar() # this is our entry box
entry2 = StringVar()
entrytext = Entry(window, textvariable=entry1) # this is our entry box
entrytext2 = Entry(window, textvariable=entry2) # this is our second entry box
#define out box
entry2 = StringVar() # this is our output box
outtext1 = Entry(window, textvariable=entry2) # this is our output box
#display boxes
entrytext.grid(row = 3, column = 2,) #display entry box
entrytext2.grid(row = 3, column = 3,) #display entry box
outtext1.grid(row = 3, column = 4,) #display output box
#place labels
box1.grid(row = 1 , column = 2, padx = 5, pady = 5)
box2.grid(row = 1 , column = 3, padx = 5, pady = 5)
box3.grid(row = 1 , column = 4, padx = 5, pady = 5)
#buttons
btn_tog2.grid(row = 4, column = 2, padx = 1, pady = 1) # addition button
btn_tog3.grid(row = 4, column = 3, padx = 1, pady = 1) # subtraction button
btn_tog4.grid(row = 5, column = 2, padx = 1, pady = 1) # multiply button
btn_tog5.grid(row = 5, column = 3, padx = 1, pady = 1) # divide button
btn_tog6.grid(row = 4, column = 6, padx = 1, pady = 1) # clear button
btn_exit.grid(row = 3, column = 6, padx = 1, pady = 1) # exit button
window.mainloop()
The code that I used for a previous application to detect if numerical values have been used is below but provided 'as is' for now.
def response():
msg = "error : must be a text value"
i = circletext.get()
y = i.isdigit()
l = len(circletext.get())
#print l
if y == True or l == 0:
circletext.insert(0,(msg))
else:
x = random.choice(RESPONSES)
circletext2.delete(0, END) # clear prev output
circletext2.insert(0,str(x)) # insert response
I will integrate a version of this in to the main code.

Addition Application
So following on from the previous posts, I am how sharing a small application, that makes use of what we have been learning.
This presents 2 input boxes and an output box, any values entered in to the first two, the sum is placed in to the last box.
This is not perfect, but getting there slowly.
We need to:-
The code for the above is as follows.
#!/usr/bin/env python
import Tkinter # note use of caps
from Tkinter import *
window = Tk()
window.title('App 1')
window.geometry("650x125") # w x h
window.resizable(0,0)
#define button actions
def btn1():
#convert box text in to integers
ent1 = int(entrytext.get())
ent2 = int(entrytext2.get())
#add the 2 integers and store in variable add
add = (ent1 + ent2)
print add
#instert value add in to box outtext
outtext1.insert(0,str(add)) # insert response
btn_tog2 = Button( window, text ='button1', command=btn1)
btn_exit = Button( window, text ='exit',command=exit)
# define some labels
box1 = Label(window, text="Entry 1: ")
box2 = Label(window, text="Entry 2: ")
box3 = Label(window, text="Ouput1: ")
#define entry box
entry1 = StringVar() # this is our entry box
entry2 = StringVar()
entrytext = Entry(window, textvariable=entry1) # this is our entry box
entrytext2 = Entry(window, textvariable=entry2) # this is our second entry box
#define out box
entry2 = StringVar() # this is our output box
outtext1 = Entry(window, textvariable=entry2) # this is our output box
#display boxes
entrytext.grid(row = 3, column = 2,) #display entry box
entrytext2.grid(row = 3, column = 3,) #display entry box
outtext1.grid(row = 3, column = 4,) #display output box
#place labels
box1.grid(row = 1 , column = 2, padx = 5, pady = 5)
box2.grid(row = 1 , column = 3, padx = 5, pady = 5)
box3.grid(row = 1 , column = 4, padx = 5, pady = 5)
#buttons
btn_tog2.grid(row = 3, column = 5, padx = 5, pady = 5)
btn_exit.grid(row = 3, column = 6, padx = 5, pady = 5)
window.mainloop()
