When I click show password it shows password but when I input 1 more letter in the entry box then that letter doesn't show up but when I input one more letter the previous letter shows up but the letter which I inputed just now doesn't show up So I want the code to update the password in the Show password label(show) in real time.
Code:
from tkinter import *
win = Tk()
no=2
def evod():
global no
no+=1
def showpwd(e):
global no, t
def bind():
text1=t.get()
btn2=Button(win, text="hide",command=hide)
btn2.grid(row=0,column=1)
show.config(text=text1)
evod()
def hide():
show.config(text="")
btn3=Button(win, text="show",command=bind)
btn3.grid(row=0,column=1)
evod()
if no % 2==0:
txt=t.get()
btn2=Button(win, text="hide",command=hide)
btn2.grid(row=0,column=1)
show.config(text=txt)
else:
show.config(text="")
btn=Button(win, text="show",command=bind)
btn.grid(row = 0, column = 1)
def bind():
show.config(text=t.get())
ent.bind("<Key>", showpwd)
t = StringVar()
ent = Entry(win,show="*", textvariable=t)
ent.grid(row = 0, column = 0)
btn=Button(win, text="show",command=bind)
btn.grid(row = 0, column = 1)
show= Label(win,text="")
show.grid(row = 1, column = 0,sticky="w")
win.mainloop()

I need your help to figure out how to make the following coding:
My idea is to get a message if fields name and quantity are in blank at the time I execute a function through a button. I printed what is the value if name and quantity are in blank and program says it is .!entry and .!entry2 respectively.
Unfortunately it doesn't work. What I am doing wrong?
if name == .!entry and quantity == .!entry2:
message = Label(root, text = 'Name and Quantity required' , fg = 'red')
message.grid(row = 4, column = 0, columnspan = 2, sticky = W + E)
return
As #JordyvanDongen pointed out in the comments you should use entry.get() to get the text inside the the entry object.
I suggest this for you code, assuming the entry objects are named name and quantity:
if not name.get() or not quantity.get():
message = Label(root, text = 'Both name and quantity are required', fg = 'red')
message.grid(row = 4, column = 0, columnspan = 2, sticky = W + E)
return None
I changed the conditional to or so that if either of the fields are blank it will be triggered but you may want to change it back to and depending on your purposes..

You can see in this particular section that you have called on 'qn' before it was even defined:
#function to display question and variables
def qn_func(self,qn_num) :
Game.clear(self)
#accessing the questions
q_file = StringIO(qn)
#reading the question, options, next qn numbers and the character name from the file
qn_list = q_file.readlines()
qn = qn_list[qn_num-1].strip().split("$")[1]
The variable needs to be assigned a value before being used. Here, you call q_file = StringIO(qn) before you have defined qn = qn_list....
I'm making a small GUI application that deals with grades and whatnot and outputs the highest grades and etc.
Here's a part of the code:
root = Tk()
gradeList = []
def addGradeObject(name, percentage):
gradeList.append(Grade(name, percentage))
updateOutput()
print(gradeList)
def undoAdd():
try:
gradeList.pop(len(gradeList) - 1)
updateOutput()
print(gradeList)
except Exception:
pass
def updateOutput():
highestGrade.setText(highest_grade(gradeList))
lowestGrade.setText(lowest_grade(gradeList))
numFailed.setText(num_failed(gradeList))
addButton = Button(text = "Add Grade", command = lambda: addGradeObject (entryA.get(), entryB.get())).grid(row = 1, column = 4)
undoButton = Button(text = "Undo", command = undoAdd).grid(row = 2, column = 4)
entryA = Entry()
entryA.grid(row = 1, column = 1)
entryB = Entry()
entryB.grid(row = 1, column = 2)
highestGrade = Entry()
highestGrade.grid(row = 2, column = 1)
lowestGrade = Entry()
lowestGrade.grid(row = 3, column = 1)
numFailed = Entry()
numFailed.grid(row = 4, column = 1)
root.title("Grade Checker")
root.mainloop()
The problem is I'm getting this error:
AttributeError: 'Entry' object has no attribute 'setText'
I don't understand. When you create an Entry box, doesn't the object of class "Entry" have an attribute/method that allows you to set text to it? I really don't know why it's not working
Entry methods can be found here. As far as I can tell, there is no setText method. There is however an insert method that you could use to set the text (though you might wand to delete the current text first).
def set_text(entry, text):
entry.delete(0, tkinter.END)
entry.insert(0 text)
Alternatively, you can hook the entry up to a StringVar and use it's .set() and .get() methods. e.g. (from the linked docs above):
v = StringVar()
e = Entry(master, textvariable=v)
e.pack()
v.set("a default value")
s = v.get()
I am new to python and recently i make dictionary using Python and Sqlite3 with tkinter.
When I run the code it returns multiple line in IDLE but in the GUI its only display the last result. I would like to display all the information in the GUI. Thanks you for any help and suggestion.

You need to change:
c.execute("SELECT * FROM laimirang WHERE lai LIKE ?", (kawl,))
c.fetchall
for member in c:
out = (member)
self.value.set(out)
print(out, )
To:
for member in c.execute("SELECT * FROM laimirang WHERE lai LIKE ?", (kawl,)):
current_text = self.value.get()
new_text = current_text +( "\n" if current_text else "") +" ".join(member)
self.value.set(new_text)
The new version gets the current value of the StringVar value and then appends the results returned with a space inbetween for each row returned with each row on its own line. What you were doing however involved just updating the StringVar to be the current member object, and therefore it only ever had the last values.
This is how it looks with more than one line:
I'm making a baseball program based on the strategy games produced by Avalon Hills from the 70s & 80s, and the last part is a gui. I've made all the code to run the game command line, and I've got the code to select lineups with a gui. I envision a 3by1 grid with a scoreboard on the first row, a text box displaying the result, out, home run, double play, etc., and the last row is divided between the pitcher and batter cards on the left side, and a frame of buttons. The frame will flip between an offence and defence frame. So first the defence frame comes up with options like pitching change, change position, and play ball. Play ball changes the frame to the offence options, which will be pinch hit, pinch run, steal, and so on. But how can I put the buttons inside a frame, then combine the player cards and buttons in another frame, and then add that to the main frame?
The DFrame & OFrame classes are inner classes (hence the "elf", not "self"). I've got the dynamic switching between the 2 Frames. My problem is breaking the DFrame main loop, it only plays the top of the first, and the self.roadOuts never increments. Here's what I've got:
while self.innings < 8.5 or self.homeScore == self.roadScore:
self.roadOuts = 0
while self.roadOuts < 3:
self.dFrame.mainloop()

elf._sacButton.grid(row = 4, column = 1)
elf._squeezeButton = Button(elf, text = 'Squeeze',
command = parent.squeeze)
elf._squeezeButton.grid(row = 3, column = 1)
the next method is called when the DFrame "play ball" button is clicked, and it makes the OFrame.
def oMenu(self):
self.dFrame.grid_forget()
self.dFrame.destroy()
self.oFrame = self.OFrame(self)
self.oFrame.grid(row = 1, column = 1)

and at the end of an at bat, I have:
self.oFrame.grid_forget()
self.oFrame.destroy()
self.dFrame = self.DFrame(self)
self.dFrame.grid(row = 1, column = 1)
I'm not sure I understand your question. It seems like you know how to put one frame in another (It is really not much different than adding a Button to a frame -- or any other widget). I think what you're asking is how to dynamically switch which frame is being displayed at any given time.
You probably want the grid_forget method. using the play_ball button should cause the defense_frame to call it's grid_forget method, while re-gridding the the offense_frame. Of course, this would be pack_forget if you're using the pack geometry manager.
EDIT
Added a very rudimentary working example of the grid layout you described. It can probably be done a lot better, but this should get you started. (Particularly the switchOffenseDefense function and the switch_button button).
