I'm working with Tkinter and I'm trying to create an attribute called wordlist for a main object that belongs to the Main1 class.
This is the Main1 class:
class Main1(Instructions):
def __init__(self, master, wordlist):
super(Main1,self).__init__(master)
self.wordlist = self.readwords()
self.textbox.insert(0.0,self.wordlist)
def create_wdgts(self):
mainlbl = Label(self,text="Tänk på ett ord!")
mainlbl.grid(row=0,column=2)
self.textbox = Text(self, width = 50, height = 5, wrap = WORD)
self.textbox.grid(column=2,row=1)
self.backbttn = Button(self,text="Tillbaka")
self.backbttn["command"] = self.back
self.backbttn.grid(column=5,row=0)
self.pointentry = Entry(self)
self.pointentry.grid(column=2, row=2)
self.pointlbl = Label(self,text = "Poäng:")
self.pointlbl.grid(column = 1, row= 2)
self.pointbttn = Button(self, text="skicka poäng")
self.pointbttn.grid(row= 2, column = 3)
self.pointbttn["command"]= self.pointhndlr()
self.crrctlbl = Label(self, text = "Rätt ord:")
self.crrctlbl.grid(column = 1, row = 3)
self.crrctentry = Entry(self)
self.crrctentry.grid(column = 2, row= 3)
self.crrctbttn = Button(self, text="skicka rätt ord")
self.crrctbttn.grid(row= 3, column = 3)
self.yesbttn = Button(self, text="Ja")
self.yesbttn.grid(row = 4, column=4)
self.nobttn = Button(self, text = "Nej")
self.nobttn.grid(row=4, column=5)
def readwords(self):
"""Returns list with all words in words.txt"""
file = codecs.open("words.txt","r","utf8")
wordlist = []
for word in file:
wordlist.append(word.strip())
return wordlist
def guess(self):
self.guesstemp = random.choice(wordlist)
self.textbox.insert(0.0,"Ange poäng för ordet '"+guesstemp+"': ")
def pointhndlr(self):
pointtemp = self.pointentry.get()
self.pointentry.delete(0)
self.wordlist = remvwords(self.wordlist,self.guesstemp,self.pointtemp,self.guesslist,self.pointlist)
I hope I don't need to post more of the program as this is already a lot of code. Anyway, I get an error message saying that my Main1 object has no wordlist attribute. Why? I created it in the init method!
Grateful for all help.

EDIT: The error is traced back to the last line, where I try to change the value of self.wordlist.
The error message is:
Exception in Tkinter callback
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/tkinter/__init__.py", line 1475, in __call__

self.textbox.insert(0.0,"Ange poäng för ordet '"+guesstemp+"': ")
NameError: global name 'guesstemp' is not defined
The reason here is that this:
super(Main1,self).__init__(master)
will in turn call this:
def create_wdgts(self):
which will in turn do this:
self.pointbttn["command"]= self.pointhndlr()
This does not assign the function self.pointhndlr to self.pointbttn["command"], instead it calls self.pointhndlr, and assigns the result to self.pointbttn["command"].
The solution: remove the parenthesis:
self.pointbttn["command"]= self.pointhndlr
The way you call super.init is wrong.
You used:
super(Main1,self).__init__(master)
You should use:
super(Main1,self).__init__(self, master)
The way you called it, the object you are creating is not initialized as an Instructions instance. Instead, the master object gets re-initialized or re-cast as an Instructions instance.

I'm trying to make a code that takes an entry from a Tkinter GUI and search through APIs blah blah blah.
But when I try to get the information from the "Entry" widget, shows this error:
Exception in Tkinter callback

Here is my code:
from tkinter import *
from tkinter.ttk import *
import base64
import requests as r
searchup = Tk()
def search():
EntryResult = Entry.get()
hypixelData = r.get('https://api.hypixel.net/player?key={MyAPIKey}&name='+EntryResult).json()
uuid = hypixelData["player"]["uuid"]
encodedData = r.get('https://sessionserver.mojang.com/session/minecraft/profile/'+uuid).json()
encodedCode = encodedData["properties"]["0"]["value"]

print(decode)
Label(searchup, text= "Search MineFriends").grid(column = 5, row = 0, sticky = W, pady = 2)
Entry(searchup).grid(column = 5, row = 1, sticky = W, pady = 2)
Button(searchup, text= "Search player!", command=search).grid(column = 5, row = 2, sticky = W, pady = 2)
searchup.mainloop()
I dont quite know the problem, Im new to Python
The get method needs to be called on an instance of Entry. You're calling it on the class Entry.
The solution looks like the following code, where an instance of Entry is created and saved in a variable named search_box. The get method of search_box is then called to get the input.
def search():
entryResult = search_box.get()
...
...
search_box = Entry(searchup)
search_box.grid(column = 5, row = 1, sticky = W, pady = 2)

I have a program that puts the contents of a dictionary in a Tkinter Listbox, but I'm having trouble deleting it from the Listbox and the dictionary.
from tkinter import *
import ast
f = open("orders.txt", "r")
contents = f.read()
f.close()
things = ast.literal_eval(contents)
secondthing = [things, "test"]
root = Tk()
f = Frame(root).pack()
l = Listbox(root)
b = Button(root, text = "delete selection", command = lambda: delete(l))
b.pack()
l.pack()
for i, j in things.items():
oneitem = i + " " + j
l.insert(END, oneitem)
def delete(listbox):
global things
# Delete from Listbox
selection = l.curselection()
l.delete(selection[0])
# Delete from list that provided it
evaluater = l.get(selection[0])
value = eval(evaluater)
ind = things.index(value)
del(things[ind])
print(things)
root.mainloop()
When I try to delete something it gives me:
Exception in Tkinter callback
Traceback (most recent call last):

value = eval(evaluater)
File "<string>", line 1
ohhh ohhhhh

SyntaxError: unexpected EOF while parsing
Can someone help me because I can delete it from the Listbox, I just have an error when deleting it from the dictionary.
The contents of orders.txt:
{"ayyy" : "ayyyyyy", "ohhh" : "ohhhhh"}
First of all, I would recommend using json or pickle to store contents of the dictionary - it's the most common practice. I don't really understand what do you want to do so I wrote a function which deletes an element from listbox and things by it's index.
An error you are getting is caused by eval function which tries to intepret your listbox item as python code. Of course, it's getting syntax error.
# Deletes element from listbox and thigs by it's index
def delete(listbox, index: int):
global things
item = listbox.get(index)
key = item.split()[0]
del things[key]
listbox.delete(index)
I get this error:

I can see from the error message that the error occurs somewhere in the line that my zip function occurs, but I have no idea what causes this. Oddly enough, this error goes away if instead of setting updateJson equal to the command value of my Tkinter button state, I set updateJson, which calls the function right as the button object is initialized. I also know what the error is saying, I just don't know where an integer is coming from, and how I can fix this issue. Any help would be appreciated.
Update: I've just found that the actual zipping of the two lists is not the problem, but when I introduce the for loop, the same error occurs.
Answering to close out this thread, answer from "user2357112 supports Monica".
The issue in this script is that for text, entry in zip(text, entry) literally uses "entry" in the for loop, and is executed after the button instance is created, meaning that if updateJson is called during the button object initialization, then there will be no error thrown as entry is still defined as a list. However, after for text, entry in zip(text, entry) executes at startup, entry is now defined as the last object in the list entry, no longer the list entry itself. When the user presses the button and updateJson is called, an error is thrown as entry is not a list anymore(I'm not 100% sure on the error part).
I'm receiving the following error:

Can anyone suggest a solution to my problem?
Thanks
In roomChanger() you assign to roomChange:
roomChange = Entry(textFrame)
so you need to mark that name as a global inside that function too. Add a global roomChange statement in that function.
displayText() on the other hand, never tries to assign to roomChange and the global statement in that function can safely be removed.
I had the same problem.
Here was my solution:
from tkinter import *
from tkinter import messagebox
Some sort of namespace glitch. That second line shouldn't be necessary. Technically from a syntax perspective import * implies import messagebox too because it's part of it all.
Use those two lines, take away import tkinter.messagebox
This is a GUI I’ve been writing for a script I already have working. What I’m struggling with here is retrieving the information in the textboxes.
Under the definition generate I am able to pop a name off of listx but I am unable to grab the local variable entry from any of the instances of the new_title_box class.

listx=[]

self.entry = StringVar()
self.name = name
self.name = ttk.Entry(mainframe,width=45,textvariable=self.entry)
self.name.grid(column=1,row=myrow+1,sticky=(N,W))
listx.append(name)
print(listx) ## For debugging to insure that it is working correctly, if it gives output it, this part works
myrow = myrow + 1
count=count+1
def make_new(*args):
new_title_box('box'+str(count))

There are two things that need to be changed to fix the problem you describe:
In the new_title_box.__init__() method change: listx.append(name) to listx.append(self.name)
In the generate() function, change: folder = boxvar.entry.get() to folder = boxvar.get().
You are appending a string to listx, use self.name instead of the local string name
