英文:
the entry .get() function is not recognized
问题
代码中的问题在于 ent_Filepath = tk.Entry(window, width=15).pack() 这一行代码中，.pack() 方法返回的是 None，因此在后续的 enter 函数中无法使用 .get() 方法。
要解决这个问题，您可以将 .pack() 拆分成两行，并将 .pack() 方法应用于单独的行，如下所示：
ent_Filepath = tk.Entry(window, width=15)
ent_Filepath.pack()
这样，您就可以在 enter 函数中使用 ent_Filepath.get() 而不会出现 "Cannot access member 'get' for type 'None'" 的错误。
此外，您的代码中还有其他地方使用了 HTML 实体编码（如 " 和 '）。如果您要在代码中使用引号或撇号，请使用原始字符而不是 HTML 实体编码，例如 "__main__" 而不是 "__main__"，'searchFile' 而不是 'searchFile'。这将有助于确保代码的正确性。
以上是代码的翻译和修复建议，如果您有任何其他问题或需要进一步的帮助，请随时提出。
英文:
if __name__ == "__main__":
import tkinter as tk
from tkinter import ttk
window = tk.Tk()
def clear():
for btn in toClear.copy():
btn.destroy()
toClear.remove(btn)
def readFilefunction():
clear()
def enter():
path = ent_Filepath.get()
readFile(path)
#window.geometry("250x75+250+75")
ent_Filepath = tk.Entry(window, width=15).pack()
btn_Enter = tk.Button(window,command=enter,text="Enter").pack()#place(x=30,y=20)
def searchFilefunction():
txt_Model = ttk.Entry(window)
txt_Size = ttk.Entry(window)
print('searchFile')
def addRecordfunction():
print('addRecord')
def modQuantityfunction():
print('modQuantity')
functions = {
"readFile": readFilefunction,
"searchFile": searchFilefunction,
"addRecord": addRecordfunction,
"modQuantity": modQuantityfunction
}
toClear = []
title = tk.Label(text= "Please choose a function")
title.pack()
toClear.append(title)
for text, fu1 in functions.items():
frame = tk.Frame(master=window)
frame.pack(side=tk.LEFT)
button = tk.Button(
master=frame,
text=text,
width=10,
height=2,
command=fu1
)
button.pack()
toClear.append(button)
window.mainloop()
the .get function gets the error
Cannot access member "get" for type "None" Pylance(reportGeneralTypeIssues)[Ln 42, Col 33]
Member "get" is unknown
and i'm not sure why
it was working but i changed something but cant remember what sorry. im not sure how to fix it from here. please dont hesitate to ask for any further details

问题是因为ent_Filepath的值为None。如果你看一下附带代码的第15行，你会发现ent_Filepath = tk.Entry(window, width=15).pack()。pack()没有返回值，所以你得到了None。你应该改成这样做：
ent_Filepath = tk.Entry(window, width=15)
ent_Filepath.pack()
英文:
The issue is caused because ent_Filepath is None. If you look at line 15 of the included code, you will see ent_Filepath = tk.Entry(window, width=15).pack(). pack() does not return a value, so you get None. What you should be doing instead is
ent_Filepath = tk.Entry(window, width=15)
ent_Filepath.pack()
