生成文本時，文本顯示 <function s at 0x000001B240AB3E2> 如何在 tkinter python 中正確顯示生成的內容？
我希望比例控制生成文本的長度，但它顯示 <function s at 0x000001B240AB3E20> 而不是 dljvdlk2okd0d

您的代碼中有幾個問題：
- 最好使用
IntVar而不是DoubleVarforv - 需要從回傳結果
s() - 使用
s()而不是s在display.insert('1.0', s)
...
v = IntVar() # use IntVar instead of DoubleVar
scale = Scale(window, variable = v, from_ = 8, to = 16, orient = HORIZONTAL)
...
def s():
return secrets.token_hex(v.get())
def password():
display = Text(window,height=1,width=32) # displays text
### use s() instead of s in below line
display.insert('1.0', s()) # inserts the pasword generator into the text
display.place(x=80,y=153) # displays the ext in a specific place
display.config(state='disabled') # prevents user from editing password
...
其實你根本不需要s()：
def password():
display = Text(window,height=1,width=32) # displays text
# call secrets.token_hex(v.get()) directly instead of s()
display.insert('1.0', secrets.token_hex(v.get()))
display.place(x=80,y=153) # displays the ext in a specific place
display.config(state='disabled') # prevents user from editing password

你應該這樣做display.insert('1.0', s())而不是僅僅s（因為最初你只是傳遞一個對 s 的參考而不是它回傳的任何字串。
您還應該以s()like的形式回傳結果，return secrets.token_hex()而不是僅僅將它們放在 parathesis 中。Python 沒有隱式回傳。
