이 튜토리얼에서는 Tkinter 를 사용하여 간단한 GUI 계산기를 만들 것입니다. 기준 치수. 트킨터 GUI 응용 프로그램을 개발하기 위한 Python 모듈에 내장되어 있습니다. 사용하기 쉽고 Python과 함께 제공됩니다. GUI 애플리케이션으로 데이터를 시각화할 수 있습니다.
간단한 GUI 계산기를 만드는 방법을 살펴보겠습니다.
-
Tkinter 에서 모든 것을 가져옵니다. *.
사용 -
계산기 인터페이스를 만드십시오.
-
입력 필드에 숫자를 입력하는 입력 함수를 만듭니다.
-
입력 필드에서 모든 것을 지우는 명백한 함수를 만듭니다.
-
그리고 마지막으로 표현식의 결과를 계산하여 제공하는 함수를 평가합니다.
예시
# importing everyting from tkinter
from tkinter import *
# expression to access among all the functions
expression = ""
# functions
def input_number(number, equation):
# accessing the global expression variable
global expression
# concatenation of string
expression = expression + str(number)
equation.set(expression)
def clear_input_field(equation):
global expression
expression = ""
# setting empty string in the input field
equation.set("Enter the expression")
def evaluate(equation):
global expression
# trying to evaluate the expression
try:
result = str(eval(expression))
# showing the result in the input field
equation.set(result)
# setting expression to empty string
expression = ""
except:
# some error occured
# showing it to the user equation.set("Enter a valid expression")
expression = ""
# creating the GUI
def main():
# main window window = Tk()
# setting the title of GUI window
window.title("Calculator")
# set the configuration of GUI window
window.geometry("325x175")
# varible class instantiation
equation = StringVar()
# input field for the expression
input_field = Entry(window, textvariable=equation)
input_field.place(height=100)
# we are using grid position
# for the arrangement of the widgets
input_field.grid(columnspan=4, ipadx=100, ipady=5)
# settin the placeholder message for users
equation.set("Enter the expression")
# creating buttons and placing them at respective positions
