Python--tkinter迷你天气预报软件(11.8)

通过做这个软件，里面有很多知识点，现在直接上代码好了

#初始化窗体
root = tkinter.Tk()
root.geometry("600x500") #设置窗口大小
root.resizable(width=False,height=False)#设置不可拉伸
root.title("妙啊专属天气预报")#设置标题

#添加背景图片
canvas = tkinter.Canvas(root,width = 600,height = 500,bg='white') #设置canvas
pil_image = Image.open('background.jpg') #打开背景图片
pil_image_resize = resize(600,500,pil_image) #将它放大保存
im = ImageTk.PhotoImage(pil_image_resize)
canvas.create_image(300,250,image = im) #将图片加载到canvas来
canvas.place(x=0,y=0,width=600,height=500)#放到屏幕当中

#添加按钮:
btn_welcome = tkinter.Button(text="点我看看",command = cherishCallBack)
btn_welcome.place(x = 270,y = 30, width = 60, height = 30)
btn_search = tkinter.Button(text="查询一下天气咯",command = searchWeather)
btn_search.place(x = 420,y = 150, width = 90, height = 30)

#添加文字：
lbl_welcome = tkinter.Label(root,text="欢迎来到这儿!") #label使用方法
lbl_welcome.place(x = 260,y = 90,width = 80,height = 30)
lbl_weather = tkinter.Label(root,text="请输入你的城市：")
lbl_weather.place(x = 60,y = 150,width = 100,height = 30)

#添加文本框
txt_city = tkinter.Entry(root)
txt_city.place(x = 250,y = 150,width = 100,height = 30)

root.mainloop()
