保存功能没有在 python 3.8.5 中弹出 window 并且也没有显示任何错误，这是什么问题？
save function not popping the window in python 3.8.5 and also not showing any error, what's the problem?
我想知道我的 python 版本是 3.8.5 的代码有什么问题.........我想要记事本中的保存文件选项
text_url = " "

我想知道如何解决这个问题或需要其他类型的编码
首先，你不应该将 text_url 初始化为 " "，因为 if text_url: 将被评估为 True。因此，您将尝试打开文件 " " 进行写入，这会引发异常。但是您的代码将忽略异常，因此您什么也看不到。
其次你不应该使用 asksaveasfile() 因为 text_url 将被分配一个打开的 File 对象。然后下次调用 save_file() 时，if text_url: 将被评估为 True，因此 with open(text_url, "w", ...) 将引发异常，因为 text_url 不是文件名。但是异常再次被忽略，没有任何反应。
下面修改new_file()和save_file()：
text_url = "" # initialize as "" instead of " "
def new_file(event=None):
global text_url
text_url = "" # initialize as "" instead of " "
text_editor.delete(1.0, tk.END)
...
def save_file(event=None):
global text_url
try:
if text_url == "":
text_url = filedialog.asksaveasfilename(defaultextension="txt",
filetypes=(("Text file","*.txt"),("All files","*.*")))
if text_url:
content = text_editor.get(1.0, tk.END)
with open(text_url, "w", encoding="utf-8") as file:
file.write(content)
except Exception as e:
print(e) # better print out exception

我想知道如何解决这个问题或需要其他类型的编码
首先，你不应该将 text_url 初始化为 " "，因为 if text_url: 将被评估为 True。因此，您将尝试打开文件 " " 进行写入，这会引发异常。但是您的代码将忽略异常，因此您什么也看不到。
其次你不应该使用 asksaveasfile() 因为 text_url 将被分配一个打开的 File 对象。然后下次调用 save_file() 时，if text_url: 将被评估为 True，因此 with open(text_url, "w", ...) 将引发异常，因为 text_url 不是文件名。但是异常再次被忽略，没有任何反应。
下面修改new_file()和save_file()：
text_url = "" # initialize as "" instead of " "
def new_file(event=None):
global text_url
text_url = "" # initialize as "" instead of " "
text_editor.delete(1.0, tk.END)
...
def save_file(event=None):
global text_url
try:
if text_url == "":
text_url = filedialog.asksaveasfilename(defaultextension="txt",
filetypes=(("Text file","*.txt"),("All files","*.*")))
if text_url:
content = text_editor.get(1.0, tk.END)
with open(text_url, "w", encoding="utf-8") as file:
file.write(content)
except Exception as e:
print(e) # better print out exception
