大家好，我是讯享网，很高兴认识大家。

用元组接收返回的多个数组

class p(object): def __init__(self): (self.x,self.y)=self.xdxx() print(self.x) def xdxx(self): a=[1,4,5,8,5] b=[4,5,8,9,9] return a,b t=p() (x,y)=xdxx() print(x) 复制代码

讯享网

讯享网n=int(input()) print(n) #这种做法完全OK 复制代码

num = 6 l1=[1,2,3,4,5,6] l2=[7,8,9,5,4,3] l=[]#不要忘记写 for i in range(num): l.append(str(l1[i])+' '+str(l2[i])) print(l) #可以运行 复制代码

获取entry的内容时踩过的坑

讯享网from tkinter import * def submit(): print(u.get()) p.set(u.get()) root = Tk() root.title("测试") frame = Frame(root) frame.pack(padx=8, pady=8, ipadx=4) lab1 = Label(frame, text="获取:") lab1.grid(row=0, column=0, padx=5, pady=5, sticky=W) #绑定对象到Entry u = StringVar() ent1 = Entry(frame, textvariable=u) ent1.grid(row=0, column=1, sticky='ew', columnspan=2) print(u.get()) lab2 = Label(frame, text="显示:") lab2.grid(row=1, column=0, padx=5, pady=5, sticky=W) p = StringVar() ent2 = Entry(frame, textvariable=p) ent2.grid(row=1, column=1, sticky='ew', columnspan=2) button = Button(frame, text="登录", command=submit, default='active') button.grid(row=2, column=1) lab3 = Label(frame, text="") lab3.grid(row=2, column=0, sticky=W) button2 = Button(frame, text="退出", command=quit) button2.grid(row=2, column=2, padx=5, pady=5) #以下代码居中显示窗口 root.update_idletasks() x = (root.winfo_screenwidth() - root.winfo_reqwidth()) / 2 y = (root.winfo_screenheight() - root.winfo_reqheight()) / 2 root.geometry("+%d+%d" % (x, y)) root.mainloop() 复制代码
