以下是修改后的代码，将按钮统一放在右边，文本框放在左边：

from tkinter import * from tkinter import filedialog from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg from PIL import ImageTk, Image

root = Tk() root.withdraw() root = Toplevel()

设置窗口大小和标题

root.title("网络攻击检测") root.geometry('1024x1024')

加载图片

bg_image = ImageTk.PhotoImage(Image.open("preview.jpg"))

创建Label

bg_label = Label(root,image=bg_image)

将Label放置在顶部

bg_label.place(x=0, y=0, relwidth=1, relheight=1)

txt = openfile() txt = pd.read_csv(txt) lb1 = Label(root, text='开始检测',font=("华文行楷",20,"italic")) lb1.place(relx=0.1, rely=0.1, relwidth=0.8, relheight=0.1)

btn4 = Button(root, text='随机森林减少特征列', font=("华文行楷",20,"italic"), command=lambda:detezhen(xtrain(x,txt,float(t_size.get())),ytrain(x,txt,float(t_size.get())))) btn4.place(relx=0.7, rely=0.5, relwidth=0.2, relheight=0.1)

var1 = StringVar() var1.set("选择你的可视化") option = ["条形图","饼图"] option_menu2 = OptionMenu(root, var1, *option) option_menu2.place(relx=0.1,rely=0.6, relwidth=0.2, relheight=0.1) btn6 = Button(root, text="可视化", font=("华文行楷",20,"italic"), command=lambda:keshihua(var1.get(),method(var.get(),xtrain(x,txt,float(t_size.get())),xtest(x,txt,float(t_size.get()))))) btn6.place(relx=0.7,rely=0.7, relwidth=0.2, relheight=0.1)
