+2407 Hello
This is about coding, not math.
I want to create a simple app, a calculator.
I "know" Python and a bit of html and javascript, however all of that is on repl.it.
Any suggestions/tips on how to create an actual app?
I'm not sure what platform to use, or how to do anything really.
I can create a "calculator" in python, but not sure how to make it look good/professional.
Thank you. :)))

+506 You could try PyGame or wxPython, and there are plenty of tutorials on YT; I experimented with both a few years ago and wxPython seems to be better for making a calculator, since it already has buttons, textboxes, and such things already defined.
Also, I never heard of repl.it; it looks pretty cool and I am going to check it out.
+2407 Thank you. :))
I've used pygame before to create things like tetris or snake, but I didn't think it would be right since buttons were hard to make.
Repl.it is great for collaboration projects since you can share it with other people, however it is a lot slower than other IDEs.

+876 Here is one I made a while ago...
from tkinter import *
def iCalc(source, side):
storeObj = Frame(source, borderwidth=4, bd=4, bg="powder blue")
storeObj.pack(side=side, expand =YES, fill =BOTH)
return storeObj
def button(source, side, text, command=None):
storeObj = Button(source, text=text, command=command)
storeObj.pack(side=side, expand = YES, fill=BOTH)
return storeObj
class app(Frame):
def __init__(self):
Frame.__init__(self)
self.option_add('*Font', 'arial 20 bold')
self.pack(expand = YES, fill =BOTH)
self.master.title('Calculator')
display = StringVar()
Entry(self, relief=RIDGE, textvariable=display,
justify='right'
, bd=30, bg="powder blue").pack(side=TOP,
expand=YES, fill=BOTH)
for clearButton in (["C"]):
erase = iCalc(self, TOP)
for ichar in clearButton:
button(erase, LEFT, ichar, lambda
storeObj=display, q=ichar: storeObj.set(''))
for numButton in ("789/", "456*", "123-", "0.+"):
FunctionNum = iCalc(self, TOP)
for iEquals in numButton:
button(FunctionNum, LEFT, iEquals, lambda
storeObj=display, q=iEquals: storeObj
.set(storeObj.get() + q))
EqualButton = iCalc(self, TOP)
for iEquals in "=":
if iEquals == '=':
btniEquals = button(EqualButton, LEFT, iEquals)
btniEquals.bind(' ', lambda e,s=self,
storeObj=display: s.calc(storeObj), '+')
else:
btniEquals = button(EqualButton, LEFT, iEquals,
lambda storeObj=display, s=' %s ' % iEquals: storeObj.set
(storeObj.get() + s))
def calc(self, display):
try:
display.set(eval(display.get()))
except:
display.set("ERROR")
if __name__=='__main__':
app().mainloop()
