大家好！在本文中，我们将研究如何创建一个 Python GUI 项目，将整数值转换为单词。
|
|||
|
|
|
|||
|
|
让我们马上开始这个项目吧！
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## 步骤 1:导入模块
|
|||
|
|
|
|||
|
|
我们首先将所有必要的模块/库导入我们的程序。
|
|||
|
|
|
|||
|
|
我们将导入`tkinter`模块来创建 GUI 窗口。与此同时，我们将导入`num2words`模块，以实现数字到文字的功能。
|
|||
|
|
|
|||
|
|
```py
|
|||
|
|
import num2words as n2w
|
|||
|
|
from tkinter import *
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
* * *
|
|||
|
|
|
|||
|
|
## 步骤 2:创建 GUI 窗口
|
|||
|
|
|
|||
|
|
现在，我们将使用基本函数创建基本的 [Tkinter](https://www.askpython.com/python-modules/tkinter/tkinter-canvas) 窗口，然后在屏幕上添加一些基本的小部件。其中一些包括标签、输入框和按钮。
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
```py
|
|||
|
|
root = Tk()
|
|||
|
|
root.title("Numbers tdo Words")
|
|||
|
|
root.geometry("650x400")
|
|||
|
|
num = StringVar()
|
|||
|
|
title = Label(root, text="Number to Words converter",fg="Blue", font=("Arial", 20, 'bold')).place(x=220, y=10)
|
|||
|
|
formats_lable = Label(root, text="Formats supported : ",fg="green", font=("Arial", 10, 'bold')).place(x=100, y=70)
|
|||
|
|
pos_format_lable = Label(root, text="1\. Positives : ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=90)
|
|||
|
|
neg_format_lable = Label(root, text="2\. Negatives ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=110)
|
|||
|
|
float_format_lable = Label(root, text="3\. Zeros ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=130)
|
|||
|
|
zero_format_lable = Label(root, text="4\. Floating points/decimals/fractions ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=150)
|
|||
|
|
num_entry_lable = Label(root, text="Enter a number :",fg="Blue", font=("Arial", 15, 'bold')).place(x=50, y=200)
|
|||
|
|
num_entry = Entry(root,textvariable=num,width=30).place(x=220, y=200)
|
|||
|
|
btn = Button(master=root, text="calculate",fg="green",
|
|||
|
|
font=("Arial", 10, 'bold'),command=num_to_words).place(x=280,y=230)
|
|||
|
|
display = Label(root, text="",fg="black", font=("Arial", 10, 'bold'))
|
|||
|
|
display.place(x=10, y=300)
|
|||
|
|
root.mainloop()
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
你可能注意到在`Line 21`中我们有按钮的`command`属性。属性被设置为`num_to_words`，但是我们还没有声明函数 yer。
|
|||
|
|
|
|||
|
|
* * *
|
|||
|
|
|
|||
|
|
## 第三步:字数函数
|
|||
|
|
|
|||
|
|
在该函数中，我们将首先读取用户给出的输入，然后使用`num2words`函数将读取的值转换为单词，最后将显示值更改为数字的计算单词形式。
|
|||
|
|
|
|||
|
|
```py
|
|||
|
|
def num_to_words():
|
|||
|
|
given_num = float(num.get())
|
|||
|
|
num_in_word = n2w.num2words(given_num)
|
|||
|
|
display.config(text=str(num_in_word).capitalize())
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
* * *
|
|||
|
|
|
|||
|
|
## 使用 Python Tkinter 将数字转换为单词
|
|||
|
|
|
|||
|
|
```py
|
|||
|
|
import num2words as n2w
|
|||
|
|
from tkinter import *
|
|||
|
|
|
|||
|
|
def num_to_words():
|
|||
|
|
given_num = float(num.get())
|
|||
|
|
num_in_word = n2w.num2words(given_num)
|
|||
|
|
display.config(text=str(num_in_word).capitalize())
|
|||
|
|
|
|||
|
|
root = Tk()
|
|||
|
|
root.title("Numbers tdo Words")
|
|||
|
|
root.geometry("650x400")
|
|||
|
|
num = StringVar()
|
|||
|
|
title = Label(root, text="Number to Words converter",fg="Blue", font=("Arial", 20, 'bold')).place(x=220, y=10)
|
|||
|
|
formats_lable = Label(root, text="Formats supported : ",fg="green", font=("Arial", 10, 'bold')).place(x=100, y=70)
|
|||
|
|
pos_format_lable = Label(root, text="1\. Positives : ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=90)
|
|||
|
|
neg_format_lable = Label(root, text="2\. Negatives ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=110)
|
|||
|
|
float_format_lable = Label(root, text="3\. Zeros ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=130)
|
|||
|
|
zero_format_lable = Label(root, text="4\. Floating points/decimals/fractions ",fg="green", font=("Arial", 10, 'bold')).place(x=200, y=150)
|
|||
|
|
num_entry_lable = Label(root, text="Enter a number :",fg="Blue", font=("Arial", 15, 'bold')).place(x=50, y=200)
|
|||
|
|
num_entry = Entry(root,textvariable=num,width=30).place(x=220, y=200)
|
|||
|
|
btn = Button(master=root, text="calculate",fg="green",
|
|||
|
|
font=("Arial", 10, 'bold'),command=num_to_words).place(x=280,y=230)
|
|||
|
|
display = Label(root, text="",fg="black", font=("Arial", 10, 'bold'))
|
|||
|
|
display.place(x=10, y=300)
|
|||
|
|
root.mainloop()
|
|||
|
|
|
|||
|
|
