Python – 海绵宝宝使用 Tkinter 模拟文本生成器 GUI

先决条件： tkinter 简介 |海绵宝宝模拟文本生成器

Python为开发 GUI（图形用户界面）提供了多种选择。在所有的 GUI 方法中，Tkinter 是最常用的方法。带有 Tkinter 的Python输出创建 GUI 应用程序的最快和最简单的方法。在本文中，我们将学习如何使用 Tkinter 创建海绵宝宝模拟文本生成器 GUI 应用程序，并提供分步指南。

创建一个 Tkinter ：

导入模块 – tkinter
创建主窗口（容器）
将任意数量的小部件添加到主窗口。
在小部件上应用事件触发器。

GUI 如下所示：

让我们创建一个基于 GUI 的 SpongeBob Mocking Text Generator 应用程序，该应用程序可以根据用户给出的输入生成 SpongeBob 文本。

下面是实现：

Python3

# import all functions from the tkinter 
from tkinter import *
 
# import the random library
import random
 
# Function to clear both the text areas
def clearAll() :
    # whole content of text area  is deleted
    text1_field.delete(1.0, END)
    text2_field.delete(1.0, END)
 
# Function to Generate SpongeBob Mocking Text
def generate() :
 
    # get a whole input content from text box
    # ignoring \n from the text box content
    input_text = text1_field.get("1.0", "end")[:-1]
     
    # variable declaration for the output text
    output_text = ""
       
    # check the cases for every individual character
    for char in input_text:
           
        # check if the character is an alphabet
        if char.isalpha():
               
            # convert to upper case
            if random.random() > 0.5:
                output_text += char.upper()
                   
            # convert to lower case
            else:
                output_text += char.lower()
           
        # if character is not and alphabet
        # add it as it is
        else:
            output_text += char
   
    text2_field.insert('end -1 chars', output_text)
 
 
# Driver code
if __name__ == "__main__" :
 
    # Create a GUI window
    root = Tk()
 
    # Set the background colour of GUI window 
    root.configure(background = 'light green') 
     
    # Set the configuration of GUI window (WidthxHeight)
    root.geometry("400x350") 
 
    # set the name of tkinter GUI window 
    root.title("Generator")
     
    # Create Welcome to SpongeBob Mocking Text Generator label 
    headlabel = Label(root, text = 'Welcome to SpongeBob Mocking Text Generator', 
                      fg = 'black', bg = "red") 
   
    # Create a "Input Text " label 
    label1 = Label(root, text = " Input Text ",
                 fg = 'black', bg = 'dark green')
       
    # Create a "Output Text " label 
    label2 = Label(root, text = "Output Text", 
                   fg = 'black', bg = 'dark green') 
     
   
    # grid method is used for placing 
    # the widgets at respective positions 
    # in table like structure .
    headlabel.grid(row = 0, column = 1)
     
    # padx keyword argument used to set padding along x-axis .
    label1.grid(row = 1, column = 0, padx = 10) 
    label2.grid(row = 3, column = 0, padx = 10)
 
       
    # Create a text area box 
    # for filling or typing the information. 
    text1_field = Text(root, height = 5, width = 25, font = "lucida 13")
    text2_field = Text(root, height = 5, width = 25, font = "lucida 13")
        
    # padx keyword argument used to set padding along x-axis .
    # pady keyword argument used to set padding along y-axis . 
    text1_field.grid(row = 1, column = 1, padx = 10, pady = 10) 
    text2_field.grid(row = 3, column = 1, padx = 10, pady = 10)
 
       
    # Create a Generate Button and attached 
    # with generate function 
    button1 = Button(root, text = "Generate", bg = "red", fg = "black",
                                command = generate)
       
    button1.grid(row = 2, column = 1)
   
    # Create a Clear Button and attached 
    # with clearAll function 
    button2 = Button(root, text = "Clear", bg = "red", 
                     fg = "black", command = clearAll)
     
    button2.grid(row = 4, column = 1)
     
    # Start the GUI 
    root.mainloop()

输出：
