Requisito previo: GUI de Python – tkinter
En este artículo, vamos a crear una calculadora científica GUI usando Python. Como puede ver, calcular números grandes hoy en día es difícil o requiere mucho tiempo. Hemos creado una GUI de calculadora científica simple usando Python que le permite realizar cálculos simples y complejos. Para implementar GUI usaremos el módulo Tkinter de Python.
Implementación paso a paso
Paso 1: módulo de importación
Python3
from tkinter import * import math import tkinter.messagebox
Paso 2: aquí crearemos geometría o un diseño para la GUI de la calculadora usando Tkinter.
Python3
root = Tk()
# sets the name on the top of the gui
root.title("Scientific Calculator")
# sets the background color of the calculator
# as white
root.configure(background = 'white')
# fixed the width and height of the gui,
# hence can't be expanded/stretched
root.resizable(width=False, height=False)
# sets the geometry
root.geometry("480x568+450+90")
# holds the buttons in the calculator,
# act as a container for numbers and operators
calc = Frame(root)
# create a grid like pattern of the frame
# i.e buttons
calc.grid()
Paso 3: Ahora crearemos una clase en la que crearemos todas las funciones de la calculadora científica para que puedan llamarse y ejecutarse fácilmente.
Python3
class Calc(): def __init__(self): self.total = 0 self.current = '' self.input_value = True self.check_sum = False self.op = '' self.result = False def numberEnter(self, num): self.result = False firstnum = txtDisplay.get() secondnum = str(num) if self.input_value: self.current = secondnum self.input_value = False else: if secondnum == '.': if secondnum in firstnum: return self.current = firstnum+secondnum self.display(self.current) def sum_of_total(self): self.result = True self.current = float(self.current) if self.check_sum == True: self.valid_function() else: self.total = float(txtDisplay.get()) def display(self, value): txtDisplay.delete(0, END) txtDisplay.insert(0, value) def valid_function(self): if self.op == "add": self.total += self.current if self.op == "sub": self.total -= self.current if self.op == "multi": self.total *= self.current if self.op == "divide": self.total /= self.current if self.op == "mod": self.total %= self.current self.input_value = True self.check_sum = False self.display(self.total) def operation(self, op): self.current = float(self.current) if self.check_sum: self.valid_function() elif not self.result: self.total = self.current self.input_value = True self.check_sum = True self.op = op self.result = False def Clear_Entry(self): self.result = False self.current = "0" self.display(0) self.input_value = True def All_Clear_Entry(self): self.Clear_Entry() self.total = 0 def pi(self): self.result = False self.current = math.pi self.display(self.current) def tau(self): self.result = False self.current = math.tau self.display(self.current) def e(self): self.result = False self.current = math.e self.display(self.current) def mathPM(self): self.result = False self.current = -(float(txtDisplay.get())) self.display(self.current) def squared(self): self.result = False self.current = math.sqrt(float(txtDisplay.get())) self.display(self.current) def cos(self): self.result = False self.current = math.cos(math.radians(float(txtDisplay.get()))) self.display(self.current) def cosh(self): self.result = False self.current = math.cosh(math.radians(float(txtDisplay.get()))) self.display(self.current) def tan(self): self.result = False self.current = math.tan(math.radians(float(txtDisplay.get()))) self.display(self.current) def tanh(self): self.result = False self.current = math.tanh(math.radians(float(txtDisplay.get()))) self.display(self.current) def sin(self): self.result = False self.current = math.sin(math.radians(float(txtDisplay.get()))) self.display(self.current) def sinh(self): self.result = False self.current = math.sinh(math.radians(float(txtDisplay.get()))) self.display(self.current) def log(self): self.result = False self.current = math.log(float(txtDisplay.get())) self.display(self.current) def exp(self): self.result = False self.current = math.exp(float(txtDisplay.get())) self.display(self.current) def acosh(self): self.result = False self.current = math.acosh(float(txtDisplay.get())) self.display(self.current) def asinh(self): self.result = False self.current = math.asinh(float(txtDisplay.get())) self.display(self.current) def expm1(self): self.result = False self.current = math.expm1(float(txtDisplay.get())) self.display(self.current) def lgamma(self): self.result = False self.current = math.lgamma(float(txtDisplay.get())) self.display(self.current) def degrees(self): self.result = False self.current = math.degrees(float(txtDisplay.get())) self.display(self.current) def log2(self): self.result = False self.current = math.log2(float(txtDisplay.get())) self.display(self.current) def log10(self): self.result = False self.current = math.log10(float(txtDisplay.get())) self.display(self.current) def log1p(self): self.result = False self.current = math.log1p(float(txtDisplay.get())) self.display(self.current) added_value = Calc()
Paso 4: El siguiente código creará una pantalla en la GUI de la calculadora al pasar el estilo de fuente, el tamaño de fuente, el color de fondo, el color de primer plano como argumento dentro de la función de entrada.
Python3
txtDisplay = Entry(calc,
font=('Helvetica', 20,
'bold'),
bg='black',
fg='white',
bd=30,
width=28,
justify=RIGHT)
txtDisplay.grid(row=0,
column=0,
columnspan=4,
pady=1)
txtDisplay.insert(0, "0")
Paso 5: Aquí crearemos un teclado numérico para la calculadora.
Python3
# store all the numbers in a variable
numberpad = "789456123"
# here i will count the rows for placing buttons
# in grid
i = 0
# create an empty list to store
# each button with its particular specifications
btn = []
# j is in that range to place
# the button in that particular row
for j in range(2, 5):
# k is in this range to place the
# button in that particular column
for k in range(3):
btn.append(Button(calc,
width=6,
height=2,
bg='black',
fg='white',
font=('Helvetica', 20, 'bold'),
bd=4, text=numberpad[i]))
# set buttons in row & column and
# separate them with a padding of 1 unit
btn[i].grid(row=j, column=k, pady=1)
# put that number as a symbol on that button
btn[i]["command"] = lambda x=numberpad[i]: added_value.numberEnter(x)
i += 1
Paso 6: Ahora colocaremos todos los botones/operadores en su respectiva posición en la grilla. Depende de usted configurarlos según su elección cambiando su valor de fila y columna. En esto, cada función de botón solo toma el nombre del operador, el ancho, la altura, el fondo, el primer plano, la fuente y la posición respectiva de columna y fila del botón como argumento.
Python3
btnClear = Button(calc, text=chr(67),

"Do you want to exit ?")
if iExit>0:
root.destroy()
return

root.geometry("480x568+0+0")
menubar = Menu(calc)
# ManuBar 1 :

menubar.add_cascade(label = 'File', menu = filemenu)
filemenu.add_command(label = "Standard", command = Standard)
