I read a lot for it and I have the sentiment that there is no solution for me.
Context: user has to enter 6-digit calculation number in the entries. The 9x entries are created by a loop. I wrote the condition to detect if the user did a mistake : number which contains less or more than 6 digit or / and contains a letter. They are working, I tested them. Only 6-digit number are accepted (if 0, it's ok since it means that the user just need to get less than 9x documents).
Goal: if the user did one mistake, a message "Error in the number" at the place of the "0" has to appear right next to the concerned and "faulty" entry.
Everything will be activated through a button.
What I tried: with a list, but it doesn't work.
How can I change the Label dynamically created by the loop ?

error_list_length=[0,0,0,0,0,0,0,0,0]

Thank you !
You can store values and objects you need to change, so then you can change them dinamically. See this example
from tkinter import *
r = Tk()
my_entries = []
for i in range(5):
e = Label(r, text=i)
my_entries.append(e)
e.pack(side='top')
r.after(4000, lambda: my_entries[2].configure(text='Example'))
r.mainloop()
EDIT 1:As TheLizzard and Cool Cloud pointed out, it's better to avoid using time.sleep() while using tkinter. Replaced with non-blocking after()
you could setup the trace function for tk.StringVar(), when user enter any value into Entry, it will be checked. for example as shown on below user only can type decimal, and you and setup length as well.

self.vars2 = tk.StringVar()
self.vars2.trace('w', partial(self.validate2, 3, 4))

self.vars3 = tk.StringVar()
self.vars3.trace('w', partial(self.validate2, 4, 3))

It does not work.
I want to design a Gui script for a NameSort script.
I could not bind the button with the function
T have tried "command=main()" and "button.bind("", func=main()"
Please help me!!!
To set a button's function in tkinter, you only pass the function itself in the command parameter i.e.
command = test1,
Not command = test1() as in this case you are just giving it the result of the function (which is None). This is so that it can execute the function each time the button is pressed.
If you want to provide in arguments for it to execute, you'll then have to use a lambda function:
command = lambda: test1(param1, param2),
You can find decent guides on buttons in tkinter here if you're interested
I have a log and quiz system using tkinter GUI. The gui screen allows for loging in and registering. This infomation is stored on an excel file saved as a csv.
The quiz portion is done on the python shell. What I want to do, is hide both the log in screen and main screen once the user has logged in and then if they choose the option of Logout, by entering 'D'. The main screen then comes back up.
I have been successful in getting rid of the main screen using the .withdraw function and can get it to appear back using, .deconify. But for some reason, I can't get rid of the log in screen.
It is possible that it's just in the wrong place, but I get an Attribute Error, which states 'function' object has no attribute 'withdraw'(I get the same for destroy)
Below is my code. It's not all of it. But the parts I think you'd need to be able to fix it.

The error i keep getting is when i try to determine weather the player has enough guesses left to keep playing. i am unable to figure it out does anyone have any idea how to fix this issue please i am stuck.
Also i am a beginner in python and i know there are other easier ways to do this i just do not know how.
here i my error i recieve:

First you initialize the variable here:
total_guesses_left = StringVar()
Then, inside if __name__ == "__main__": you write:
guessed_letter = []
// ...
total_guesses_left.set(guessed_letter)
So our StringVar instance stored as total_guesses_left gets its value set to an empty list. As it's a StringVar, this leads to a conversion, which means that its internal value now is the string "[]".
Then in your initalize_loop, you try to do
total_guesses = int(total_guesses_left.get())
Of course total_guesses_left.get() will return a string, or more precisely it will return the string "[]".
And as int parses strings representing numbers with a specific base (by default 10), it can only handle strings consisting of alphanumeric characters, and only if they only contain characters used by the specified number base (i.e. by default those are only the characters 0123456789).
Therefore you get the exception that "[]" can not be parsed as int.
You probably want total_guesses_left to store a valid integer representation string and not one of a list.
It means at that moment your total_guesses_left.get() is giving '[]'. base 10 error arises when you try to convert a char or something other than a number which is as a string like
>>> str1='a'
>>> int(str1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'a'
>>> alist='[]'
>>> int(alist)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '[]'
I hope you understand the error. Play around a little with errors. "Trial And Error " :D
Hello :) In the typing practice program I am creating in python 3, I have a for...loop that takes the characters from a global list of a certain paragraphs characters and compares it to the character the user is typing.
For some reason, the for loop wont iterate and won't go on to the next character. After some research, I figured out that you have to use local variables in order to do this but that doesn't work either. Here is my code:
import random
from tkinter import *
root=Tk()
a_var = StringVar()
words = []
eachword = []
global eachchar
charlist = []
x=random.randint(0,10)
def typingpractice():
realcharlist = []
something = []
paralist = []
#x=random.randint(0,10)
file = open("groupproject.txt")
line = file.readline()
paraWords = []
for line in file:
newline = line.replace("\n","")
paralist.append(line.replace("\n", ""))
paraWords.append(newline.split(" "))
wordList = []
for c in paraWords[x]:
charlist.append(c)
for b in range(0,len(charlist)):
wordList.append(charlist[b])
#print (wordList)
for p in charlist[b]:
realcharlist.append(p)
#print(realcharlist)
a=Canvas(root, width=500, height=500)
a.pack()
a.create_text(250,50, text = "Typing Fun", width = 500, font = "Verdana", fill = "purple")
a.create_text(250,300, text = paralist[x], width = 500, font = "Times", fill = "purple")
a = Entry(root, width = 100)
a.pack()
a.focus_set()
a["textvariable"] = a_var
def compare(s, realcharlist):
for g in realcharlist:
print ("s:",s)
print ("g:",g)
if s == g:
print ("y")
a['fg'] = 'green'
break
else:
print ("n")
a['fg'] = 'red'
break
def callback(*args):
global s
# print ("b:",xcount)
s = a.get()
s = s[-1:]
compare(s, realcharlist)
a_var.trace_variable("w", callback) #CALL WHEN VARIABLE IS WRITTEN
def practicetest():
print ("nothing here yet")
b = Button(root, text="Start Practice", command=typingpractice)
b.pack()
d = Button(root, text="Test", command=practicetest)
d.pack()
root.mainloop()
The text file "groupproject.txt" is an external text file that contains 10 one-line paragraphs, each character of each paragraph is being compared to what the user is typing in.
Any help on how to make the for loop work would be greatly appreciated. Thanks :D
Basically what happened was there was a break in the for loop so it would always iterate itself starting from 0 again.
