因為你點一次都執行一次nameget函數，用意應該跟剛才的差不多，while并不能循環，可以反過來實現，通過while控制b1這個button，沒時間弄，我就跟剛才的那樣差不多修改了下
from Tkinter import * import tkMessageBox master = Tk() e = Entry(master) e.pack() e.focus_set() global namelist namelist = [] def clr_text(): e.delete(0, END) def nameget(): morename = "yes" n=len(namelist)+1 while morename == "yes": name = e.get() namelist.append(name) morename = tkMessageBox.askyesno("Question","yes:input another name;no:view name list") print n,namelist b2 = Button(master, text="clear", width=10, command=clr_text) b2.pack() b1 = Button(master, text="comfirm", width=10, command=nameget) b1.pack() mainloop() |

我感覺，首先namelist得用global變量，否則每次調用nameget都會清空namelist。在這個思路的基礎上，while循環是沒有必要的，是/否的選擇也不是很重要。我修改的版本是這樣：
from Tkinter import *import tkMessageBoxmaster = Tk()e = Entry(master)e.pack()e.focus_set() namelist = [] def clr_text(): e.delete(0, END) def nameget(): global namelist, n_namelist #morename = "yes" #while morename == "yes": name = e.get() namelist = namelist + [name] morename = tkMessageBox.askyesno("Question","yes:input another name; no:view name list") print len(namelist), namelist b2 = Button(master, text="clear", width=10, command=clr_text)b2.pack()b1 = Button(master, text="comfirm", width=10, command=nameget)b1.pack()mainloop() |
如果題主要更清晰準確地實現添加名單、查看名單，應該進一步修改界面。
