我在python 3.4中使用Tkinter制作基于文本的游戏,我无法弄清楚如何从Entry小部件中获取字符串,它只返回Py_Var#
,#是一个数字。我已经查看了类似问题的答案,但是没有一个能够与我需要的东西完全一致。这是相关的代码片段:
from tkinter import *
win = Tk()
win.geometry("787x600")
playername = StringVar()
def SubmitName():
playername.get
#messagebox.showinfo("Success", playername)
print(playername)
frame3 = Frame(win)
frame3.pack()
label1 = Label(frame3, text="You awaken in a room, with no memories of yourself or your past. ")
label2 = Label(frame3, text="First, how about you give yourself a name:")
label1.config(font=("Courier", 11))
label2.config(font=("Courier", 11))
entry1 = Entry(frame3, textvariable=playername)
entry1.config(font=("Courier", 11))
label1.grid(row=0, column=0, columnspan=3)
label2.grid(row=1, column=0)
entry1.grid(row=1, column=1)
bnamesub= Button(frame3, text="Submit", command=lambda: SubmitName())
bnamesub.grid()
win.mainloop()
此外,第一次使用stackoverflow及其读取很奇怪,但没有。

SubmitName()
中有两个错误。
首先,你需要得到这样的文字:
txt = playername.get()
然后您需要打印txt
:
print(txt)
您错误地打印了StringVar
变量本身。

from tkinter import *
import pickle
win = Tk()
win.geometry("787x600")
def SubmitName():
playername = entry1.get()
messagebox.showinfo("Success", playername)
print(playername)
frame3 = Frame(win)
frame3.grid()
label1 = Label(frame3, text="You awaken in a room, with no memories of yourself or your past. ")
label2 = Label(frame3, text="First, how about you give yourself a name:")
label1.config(font=("Courier", 11))
label2.config(font=("Courier", 11))
#name entered is a StringVar, returns as Py_Var7, but I need it to return the name typed into entry1.
entry1 = Entry(frame3)
entry1.config(font=("Courier", 11))
label1.grid(row=0, column=0, columnspan=3)
label2.grid(row=1, column=0)
entry1.grid(row=1, column=1)
bnamesub= Button(frame3, text="Submit", command=lambda: SubmitName())
bnamesub.grid()
我改变了什么:
-deleted playername = StringVar()
。我们真的不需要它;
- 在函数内部更改:将playername.get
更改为playername = entry1.get()
;
-added frame3.grid()
(没有几何管理,小部件无法在屏幕上显示。);
- 另外,一点点编辑:在Python中,使用#
符号创建注释。所以我将*
更改为#
。

我很高兴在这里找到一个解决方案,但所有这些“按原样”的答案均不适用于我的设置python3.8,pycharm 2018.2 因此,如果任何人都可以回答这个问题,看来entry1.get()不能用作字符串。我首先想将其添加到列表中,然后我做了一个更简单的版本来指出问题所在:
from tkinter import *
import pickle
win = Tk()
win.geometry("300x300")
#playername = StringVar()
def SubmitName():
labell = Label(win, text="Little tryup").grid()
playername = entry1.get()
# result about line 11: 'NoneType' object has no attribute 'get'
labelle = Label(win, text=playername).grid()
# print(txt)
label1 = Label(win, text="Enter a name:").grid()
entry1 = Entry(win).grid()
boutonne = Button(win, text="label-it!", command=lambda: SubmitName())
boutonne.grid()
win.mainloop()
