I am creating a GUI that has two different types on entry for info. One is the checkbox and the other is the entry field. I want to have the show button display both inputs but I cannot seem to make it work in one button. I can change it to show one or the other. I am not sure what I am doing wrong to make both inputs display from the same button. Here is the code that I have. Right now it will display the entry field information, not the checkbox
import tkinter as tk
from tkinter import *
def show_entry_fields():
print("First Name: %s\nLast Name: %s\nPhone Number: %s"% (e1.get(),e2.get(), e3.get()))
master = tk.Tk()
master.title("Personal Info")
Label(master, text="Your gender:").grid(row=0,column=0, sticky=W)
var1 = IntVar()
Checkbutton(master, text="male", variable=var1).grid(row=0, column=1, sticky=W)
var2 = IntVar()
Checkbutton(master, text="female", variable=var2).grid(row=0, column = 2, sticky=W)
tk.Label(master, text="First Name").grid(row=1, pady=3)
tk.Label(master, text="Last Name").grid(row=2, pady=3)
tk.Label(master, text="Phone Number").grid(row=3, pady=3)
e1 = tk.Entry(master)
e2 = tk.Entry(master)
e3 = tk.Entry(master)
e1.grid(row=1, column=1, pady=3)
e2.grid(row=2, column=1, pady=3)
e3.grid(row=3, column=1, pady=3)
tk.Button(master, text='Quit', fg="red", command=master.quit).grid(row=4,column=0, sticky=tk.E, pady=10)
tk.Button(master, text='Show', fg="blue", command=show_entry_fields).grid(row=4, column=1, sticky=tk.W, padx=50, pady=10)
tk.mainloop()
if you want to get just one output( male or female ) which is the logic here with gender input .. then you have to use RadioButton not CheckButton
so your code will be like that:
import tkinter as tk
from tkinter import *
def show_entry_fields():
print("First Name: %s\nLast Name: %s\nPhone Number: %s\n gender: %s"% (e1.get(),e2.get(), e3.get(), var1.get()))
master = tk.Tk()
master.title("Personal Info")
Label(master, text="Your gender:").grid(row=0,column=0, sticky=W)
var1 = StringVar()
Radiobutton(master, text="male", variable=var1, value="male").grid(row=0, column=1, sticky=W)
Radiobutton(master, text="female", variable=var1, value="female").grid(row=0, column = 2, sticky=W)
tk.Label(master, text="First Name").grid(row=1, pady=3)
tk.Label(master, text="Last Name").grid(row=2, pady=3)
tk.Label(master, text="Phone Number").grid(row=3, pady=3)
e1 = tk.Entry(master)
e2 = tk.Entry(master)
e3 = tk.Entry(master)
e1.grid(row=1, column=1, pady=3)
e2.grid(row=2, column=1, pady=3)
e3.grid(row=3, column=1, pady=3)
tk.Button(master, text='Quit', fg="red", command=master.quit).grid(row=4,column=0, sticky=tk.E, pady=10)
tk.Button(master, text='Show', fg="blue", command=show_entry_fields).grid(row=4, column=1, sticky=tk.W, padx=50, pady=10)
tk.mainloop()
but let's say you have a list of options like preferred languages for example and you want to get the output of what exactly the user chooses .. in that case you should use ListBox

I am trying to get the text username and password in the below Tkinter to be next to the Entry, I have tried to play with the columns but it didn't fix it. I was previously using pack() but switched to grid() to be more in control of the location of the labels.
Here is the code:
root = Tk()
root.title("Bookmark Search")
root.resizable(0,0)
greeting= Label(root, text="Hi, This is a Trial to see how the label works !")
help=Label(root, text=" How can I help you today?")
greeting.grid(row = 0, column= 1, pady=5, padx=200)
help.grid(row = 1, column= 1,pady=5)
e = Entry(root, width=50)
e.grid(row=2, column = 1,rowspan=2, pady=15)
mySubmit = Label(root)
-------several lines of unrelated code-------
mySubmit.bind("<Button-1>", open_url)
root.bind('<Return>', myClick)
myButton= Button(root, text="Submit", command=myClick)
myButton.grid(row=4, column = 1,rowspan=2, pady=10)
# username
username_label = Label(root, text="Username:")
username_label.grid(column=0, row=8, padx=5, pady=5)
username_entry = Entry(root)
username_entry.grid(column=1, row=8, padx=5, pady=5)
# password
password_label = Label(root, text="Password:")
password_label.grid(column=0, row=9, padx=5, pady=5)
password_entry = Entry(root)
password_entry.grid(column=1, row=9, padx=5, pady=5)
# login button
login_button = Button(root, text="Login")
login_button.grid(column=1, row=10,padx=5, pady=5)
root.mainloop()
Here is a print screen of the current output:
Here is the required output:
You can put Labels and Buttons in Frame and then Frame put in main window.

PEP 8 -- Style Guide for Python Code
from tkinter import *
win=Tk()
var = StringVar()
l = Label(win, bg='white', width=15)
l.grid(row=17,column=1,padx=10, pady=10, sticky='w')
def print1_selection():
if var.get()=="Number":
lab1= Label(win, text="Enter a number").grid(row=4, column=0)
ent1=Entry(win).grid(row=4, column=1)
l.config(text='you have selected ' + var.get())
elif var.get()=="Alphabet":
lab21= Label(win, text="Enter an alphabet").grid(row=5, column=0)
ent21=Entry(win).grid(row=5, column=1)
l.config(text='you have selected ' + var.get())
lbl4=Label(win, text="Select One", bg="crimson", fg="white", font=("times new
roman",15,"bold")).grid(row=1, column=0, padx=10, pady=10, sticky='w')
r1 = Radiobutton(win, text='Number',variable=var, value='Number', command=print1_selection, width=22)
r1.grid(row=2,column=0,padx=10, pady=10)
r2 = Radiobutton(win, text='Alphabet', variable=var, value='Alphabet', command=print1_selection, width=22)
r2.grid(row=2,column=1,padx=10, pady=10)
win.mainloop()
In this code I want that when I select radiobutton number, only enter a number should appear and same for the other.
But the problem is that when I select number after selecting alphabet, it shows both. I need only the selected one and eliminate the other instantly.
This is how I would approach this issue:
from tkinter import Tk, StringVar, Label, Frame, Entry, Radiobutton
def print1_selection():
for widget in entry_frame.winfo_children():
widget.destroy()
value = var.get()
lbl.config(text='You have selected ' + value)
if value == "Number":
Label(entry_frame, text="Enter a number").grid(row=0, column=0)
Entry(entry_frame).grid(row=0, column=1)
elif value == "Alphabet":
Label(entry_frame, text="Enter an alphabet").grid(row=0, column=0)
Entry(entry_frame).grid(row=0, column=1)
win = Tk()
var = StringVar(value=0)
entry_frame = Frame(win)
entry_frame.grid(row=2, column=0, columnspan=2)
lbl = Label(win, bg='white', width=20)
lbl.grid(row=3, column=0, columnspan=2, padx=10, pady=10, sticky='w')
Label(win, text="Select One", bg="crimson", fg="white", font=("times new roman", 15, "bold")).grid(row=0, column=0, padx=10, pady=10, sticky='w')
Radiobutton(win, text='Number', variable=var, value='Number', command=print1_selection, width=22).grid(row=1, column=0, padx=10, pady=10)
Radiobutton(win, text='Alphabet', variable=var, value='Alphabet', command=print1_selection, width=22).grid(row=1, column=1, padx=10, pady=10)
win.mainloop()
As You can see if You don't plan on using the widgets instance anywhere You don't have to assign it to a variable. Also no need to configure label in both statements since that will be done anyways so just do it at the beginning, also rows start from 0 too. Frames help with organizing widgets. Also if You want neither of the radiobuttons selected set the variable to 0.
I have made a program where the user enter's a target number and 4 other numbers to make that target number. Right now I am having trouble to intergrate my tkinter interface to my code. So I am hoping that some one can help me
Tkinter interface:
window = Tk()
window.title("target number solution")
Label(window,image='', bg="white") .grid(row=0, column=0, sticky=W)
Label(window, text="Enter target number:",bg="black", fg="white", font="none 12 bold").grid(row=1, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=2, column=0, sticky=N)
Label(window, text="Enter first number:",bg="black", fg="white", font="none 12 bold").grid(row=4, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=5, column=0, sticky=N)
Label(window, text="Enter second number:",bg="black", fg="white", font="none 12 bold").grid(row=6, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=7, column=0, sticky=N)
Label(window, text="Enter third number:",bg="black", fg="white", font="none 12 bold").grid(row=8, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=9, column=0, sticky=N)
Label(window, text="Enter fourth number:",bg="black", fg="white", font="none 12 bold").grid(row=10, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=11, column=0, sticky=N)
Button(window, text="Solve", width=6, command=solver).grid(row=12, column=0, sticky=N)
output = Text(window, width=60, height=10, wrap=WORD, background="white")
output.grid(row=13, column=0, columnspan=1, sticky=N)
window.mainloop()
This is the code that needs to be linked with the tkinter interface:
from itertools import permutations,combinations_with_replacement
numbers = []
target = int(input())
operators = ["+","-","*","/"]
groups = ['X+X+X+X', 'X+X+(X+X)', 'X+(X+X)+X', '(X+X+X)+X', '(X+X)+X+X', 'X+(X+X+X)', '((X+X)+X)+X', 'X+(X+(X+X))', 'X+((X+X)+X)', '(X+X)+(X+X)', '(X+(X+X))+X']
seen = set()
for values in permutations(numbers,len(numbers)):
for operCombo in combinations_with_replacement(operators,len(numbers)-1):
for oper in permutations(operCombo,len(numbers)-1):
formulaKey = "".join(oper+values)
if formulaKey in seen: continue # ignore variations on parentheses alone
for pattern in groups:
formula = "".join(o+p for o,p in zip([""]+list(oper), pattern.split("+")))
formula = "".join(v+p for v,p in zip([""]+list(values),formula.split("X")))
try:
if eval(formula) == target:
global Answer
Answer = formula,"=",target
print(formula,"=",target)
seen.add(formulaKey)
break
except: pass
All suggestions will be grealty appriciated
You can store the values for each number in seperate IntVar variables, then get the values of these variables inside the solver function and perform all the operations that are in your second code. The code should be modularised with the use of a class containing functions that create the widgets and run the solver code. To read more about class-based declarations in Tkinter, read this.

A few things that you can change/try:
Keep the "Entry" variables unique. Then extract each number using .get() command.
Use lambda in the command options of the Button as follows:
command = lambda: solver(num1, num2, num3, num4)
And if you want to display your returned number from 'solver', grid a Label in your tkinter window. Then use Label.config(text="Your number here") to show it in your tkinter window
So I'm trying to make this tkinter GUI in which you can add or search for a customer (the customer is stored in a SQlite database). Problem is, I can't see a way of making the def for when the add customer button is pressed, for as far as I know, I would need to use the names of the variables from lower down in the program where the widgets are created. I could switch the order of the functions around, but then the widgets would be calling functions that have not already been created. Can someone help fix this probem? Thanks in advance.
Here's the code:
from tkinter import *
app = Tk()
app.minsize(400,420)
app.title("Gatecode Manager")
app.resizable(False, False)
def add():
first = createWindow().firstAdd.get()
last = createWindow().firstAdd.get()
phone = createWindow().numberAdd.get()
def createWindow():
Label(text="Welcome to Gatecode Manager", font=("bold", 17)).grid(row=0, columnspan=2, pady=30, sticky=N)
Label(text="Search for a Customer").grid(row=1, column=0, padx=30, pady=10)
Label(text="First Name:").grid(row=2, column=0, padx=30, pady=10)
firstSearch = Entry().grid(row=3, column=0, padx=30)
Label(text="Last Name:").grid(row=4, column=0, padx=30, pady=10)
lastSearch = Entry().grid(row=5, column=0, padx=30)
Label(text="Add Customer to System").grid(row=1, column=1, padx=30, pady=10)
Label(text="First Name:").grid(row=2, column=1, padx=30, pady=10)
firstAdd = Entry().grid(row=3, column=1, padx=30)
Label(text="Last Name:").grid(row=4, column=1, padx=30, pady=10)
lastAdd = Entry().grid(row=5, column=1, padx=30)
Label(text="Phone Number:").grid(row=6, column=1, padx=30, pady=10)
numberAdd = Entry().grid(row=7, column=1, padx=30)
add = Button(text="Add", command="null").grid(padx=30, pady=10, column=1)
app.mainloop()
createWindow()
I find it difficult to understand exactly how you want this program to function. Is the add button supposed to call the function add() which then calls createWindow()?
I'm guessing a little here but what about:
1) Don't create the GUI in a function. A function will keep the variables in the scope of the functioin.
2) Use StringVar() to access entries. Since you don't save the identity of your entries it becomes impossible to interrogate them.
Example:
from tkinter import *
app = Tk()
app.minsize(400,420)
app.title("Gatecode Manager")
app.resizable(False, False)
def add():
first = firstAddVar.get()
last = firstAddVar.get()
phone = numberAddVar.get()
Label(text="Welcome to Gatecode Manager", font=("bold", 17)).grid(row=0,
columnspan=2, pady=30, sticky=N)
Label(text="Search for a Customer").grid(row=1, column=0, padx=30, pady=10)
Label(text="First Name:").grid(row=2, column=0, padx=30, pady=10)
firstSearchVar = StringVar()
firstSearch = Entry(textvar=firstSearchVar).grid(row=3, column=0, padx=30)
Label(text="Last Name:").grid(row=4, column=0, padx=30, pady=10)
lastSearchVar = StringVar()
lastSearch = Entry(textvar=lastSearchVar).grid(row=5, column=0, padx=30)
Label(text="Add Customer to System").grid(row=1, column=1, padx=30, pady=10)
Label(text="First Name:").grid(row=2, column=1, padx=30, pady=10)
firstAddVar = StringVar()
firstAdd = Entry(textvariable=firstAddVar).grid(row=3, column=1, padx=30)
Label(text="Last Name:").grid(row=4, column=1, padx=30, pady=10)
lastAddVar = StringVar()
lastAdd = Entry(textvariable=lastAddVar).grid(row=5, column=1, padx=30)
Label(text="Phone Number:").grid(row=6, column=1, padx=30, pady=10)
numberAddVar = StringVar()
numberAdd = Entry(textvariable=numberAddVar).grid(row=7, column=1, padx=30)
add = Button(text="Add", command=add).grid(padx=30, pady=10, column=1)
app.mainloop()
When your GUIs become more complex you should study OOP.
I am little bit comfused with grid system in tkinter Python. Can anyone show how to make it in right way?! ListBox and Label items positions are not in the places where I expexted to see them.
CODE:
self.third_label = Label(self, text="TEXT")
self.third_label.grid(row=2, column=0, columnspan=4, padx=10, pady=10, sticky=W)
self.fourth_label = Label(self, text="LONG TEXT")
self.fourth_label.grid(row=2, column=1, columnspan=4, padx=10, pady=10, sticky=W)
self.fifth_label = Label(self, text="SOME TEXT")
self.fifth_label.grid(row=2, column=2, columnspan=6, padx=10, pady=10, sticky=W)
self.sixth_label = Label(self, text="BIG TEXT")
self.sixth_label.grid(row=2, column=3, columnspan=4, padx=10, pady=10, sticky=W)
self.first_listbox = Listbox(self, width=40, selectmode=EXTENDED)
self.first_listbox.grid(row=3, column=0, columnspan=4, padx=10, pady=10, sticky=W)
self.second_listbox = Listbox(self, width=40, selectmode=EXTENDED)
self.second_listbox.grid(row=3, column=2, columnspan=4, padx=10, pady=10, sticky=W)
self.third_listbox = Listbox(self, width=40, selectmode=EXTENDED)
self.third_listbox.grid(row=3, column=4, columnspan=4, padx=10, pady=10, sticky=W)
self.fourth_listbox = Listbox(self, width=40, selectmode=EXTENDED)
self.fourth_listbox.grid(row=3, column=6, columnspan=4, padx=10, pady=10, sticky=W)
What I have right now:
Just Example:
The grid system works fine. The problem is your columnspans, which don't make much sense. You're gridding the widgets into certain column positions then giving them a columnspan that is beyond the range of where the next widget is to be gridded so on and so forth.
Small example:
import string
import tkinter as tk
root = tk.Tk()
for i in range(3):
tk.Label(root, text=string.ascii_letters).grid(row=0, column=i)
tk.Listbox(root, width=40).grid(row=1, column=i)
root.mainloop()
Edit from comments (for listbox size):
To get the number of lines in a listbox you can use the .size() method.
