跳到 open_gn() 一個，因為這就是問題所在。我想制作一個可以進行統計/隨機相關內容的應用程式，并在其中創建一個可以生成亂數的應用程式。應用程式會生成數字，但之前的值會保留并干擾正在生成的當前數字。
uj5u.com熱心網友回復：
每當執行時您都會創建新標簽generate_number()，并將新標簽放在將覆寫先前標簽的相同位置。
您需要在函式外部創建標簽，然后在函式內部更新其文本：
def open_gn():
...
Label(gn_wn, text="Random value is: ").place(x=40, y=40)
# create label for generated random number
d_rn = Label(gn_wn, font=("Yu Gothic UI", 30))
d_rn.place(x=40, y=100)
def generate_number():
min_ = int(entry_min.get())
max_ = int(entry_max.get())
random_num = r.randint(min_, max_)
d_rn.config(text=random_num) # update label
...
