问题描述
I have to do a little program, I have to calculate the percentage of savings a user has using the information the user provides.
我必须做一个小程序，我必须使用用户提供的信息来计算用户节省的百分比。 So this is my code所以这是我的代码
savings_box = tk.Entry(new_goal_window, width=75)
savings_box.place(x=450,y=150)

Convert the values from strings to floats:将值从字符串转换为浮点数：
percentage = (float(savings_box.get()) / float(goal_total.get())) * 100
