Python/Tinker 'datetime.date' 对象没有属性 'get' （在记事本文档中输入日期）

Question

我是新来的

为了了解基本编码的工作原理，我创建了一个 GUI，最终用户可以在其中将文本输入到输入小部件中，按下按钮，文本将显示在 shell 上保存记事本。

我的 GUI 有三个按钮；

按钮 1 会将在 GUI 中输入的文本保存到记事本并通过 shell
按钮2是将今天的日期保存到记事本并通过shell
按钮 3 打开记事本 .exe 文件

我能够成功地将文本保存到记事本中并通过 GUI 应用程序打开记事本。但是，我无法在记事本中保存日期。

这是显示属性错误的代码示例。（单击按钮 2 时）

 #030820, printing time  to shell and notepad # in progress
def button1Click():
    print (time.get)
    with open("Names101.txt", "a") as output:  #prints to notepad 
        output.write(time.get() + "\n") #prints to notepad
    
button1 = tk.Button(window, text=("Record Time"),width = 30, command=button1Click, bg="light blue")

这是显示的错误

File "C:\Users\shane\AppData\Local\Programs\Python\Python38- 
32\lib\tkinter\__init__.py", line 1883, in __call__
return self.func(*args)
File "C:\Users\shane\source\repos\GUI input to Notepad\GUI input to 
Notepad\GUI_input_to_Notepad.py", line 16, in button1Click
print (time.get)
AttributeError: 'datetime.date' object has no attribute 'get'
The thread 'MainThread' (0x1) has exited with code 0 (0x0).
The program 'python.exe' has exited with code -1 (0xffffffff).

这是我的应用程序的完整代码

import tkinter as tk
import datetime
import os #opens a text file 
window = tk.Tk()
window.title ("Shane's Text to NotePad Testing GUI")
window.geometry("400x150")
window.configure(bg="#3BB9FF")

time = datetime.date.today()
print (time)


#030820, printing time  to shell and notepad # in progress
def button1Click():
    print (time.get)
    with open("Names101.txt", "a") as output:  #prints to notepad 
        output.write(time.get() + "\n") #prints to notepad
        

button1 = tk.Button(window, text=("Record Time"),width = 30, command=button1Click, bg="light blue")



#button3 opens txt file
def button3Click():
    os.system("Names101.txt")

button3 = tk.Button(window, text=("Open Notepad file"),width=30, command=button3Click, bg="light green")






#030820, printing entry1 to shell and notepad 

entry1 = tk.Entry(window, width = 50)

def entry1get():    
    print (entry1.get())    #prints to shell
    with open("Names101.txt", "a") as output:  #prints to notepad
        output.write(entry1.get() + "\n")   #prints to notepad
    
                

button2 = tk.Button(window, text="Input text to notepad", width=30, command=entry1get, bg="#E6E6FA")
    
    

#030820 Label one 


label1 = tk.Label(text="Enter text below", font="bold" , bg="#3BB9FF")   




label1.pack() 
entry1.pack() 
button2.pack() 
button1.pack() 
button3.pack()



window.mainloop()

Lewis Morris 回答的问题，以下是解析

def button1Click():
print (time.strftime("%Y-%m-%d"))
with open("Names101.txt", "a") as output:  #prints to notepad 
    output.write(time.strftime("%Y-%m-%d") + "\n")  #prints to notepad
    

button1 = tk.Button(window, text=("Record Time"),width = 30, 
command=button1Click, bg="light blue")

Answer 1

打印日期时可以使用.strftime()方法。

这允许您以任何您希望的方式打印和格式化您的日期时间。

即

初始化你的日期。

time = datetime.date.today()

然后使用传递的参数调用 strftime()，例如

time.strftime("%Y-%m-%d")

然后打印如下

print(time.strftime("%Y-%m-%d"))

可在此处找到完整的 strftime 代码列表

Answer 2

变量time初始化为：

time = datetime.date.today()

根据 datetime docs，没有对应于您对 time.get 或 time.get() 的使用的属性或 class 方法。

此更改应该可以解决您的问题：

def button1Click():
    print (time)
    with open("Names101.txt", "a") as output:  #prints to notepad 
        output.write(str(time) + "\n") #prints to notepad
