I've been having some troubles with this code as the if condition cannot be true and always executes the else condition instead.
can you help
`
from tkinter import *
root = Tk()
entry_1 =Entry(root, width = 20)
entry_1.pack()
entry_1.insert(0, "Choose Your Number ")
def m():
answer = entry_1.get().strip()
if answer == 5 :
mylabel = Label(root, text = "YOU WIN!")
mylabel.pack()
else :
mylabel = Label(root, text = "YOU LOST!")
mylabel.pack()
mybutton = Button(root, text = 'PLAY', command = m)
mybutton.pack()
root.mainloop()
Thanks
Any user input is a string, so you need to convert to an Integer.
Try this code:
from tkinter import *
root = Tk()
entry_1 =Entry(root, width = 20)
entry_1.pack()
entry_1.insert(0, "Choose Your Number ")
def m():
answer = int(entry_1.get().strip())
if answer == 5 :
mylabel = Label(root, text = "YOU WIN!")
mylabel.pack()
else :
mylabel = Label(root, text = "YOU LOST!")
mylabel.pack()
mybutton = Button(root, text = 'PLAY', command = m)
mybutton.pack()
root.mainloop()

here is my code:
from tkinter import *
import random
def initGame():
window = Tk()
window.title("Guess the number game")
lbl = Label(window, text="Guess number from 1 to 100. Insert how many tries would you like to have: ", font=("",16))
lbl.grid(column=0, row=0)
txt = Entry(window, width=10)
txt.grid(column=0, row=1)
txt.focus() #place cursor auto
def clicked():
number_dirty = txt.get()
tries = int(number_dirty)
playGame(tries)
btn = Button(window, text="Start", command=clicked)
btn.grid(column=0, row=2)
window.geometry('800x600')
window.mainloop()
def playGame(tries):
number_of_tries = int(tries)
number = random.randint(1,100)
higher_notification = "Number is HIGHER"
lower_notification = "Number is LOWER"
game_window = Tk()
game_window.title("Game Window")
lbl = Label(game_window, text="Guess numbers between 1 and 100, you have %s tries !" %(number_of_tries), font=("",14))
lbl.grid(column=0, row=0)
txt = Entry(game_window, width=10)
txt.grid(column=0, row=1)
txt.focus()
print(number)
print(number_of_tries)
def clicked():
user_input = txt.get()
compareNumbers(number, user_input)
btn_try = Button(game_window, text="Try!", command="clicked")
btn_try.grid(column=0, row=2)
def compareNumbers(number, user_input):
if user_input == number:
messagebox.showinfo('You have won!', 'Right! the number was %s ' %(number))
else:
if user_input > number:
lbl.configure(lower_notification)
number_of_tries -1
else:
lbl.configure(higher_notification)
number_of_tries -1
game_window.geometry('600x600')
game_window.mainloop()
initGame()
On the first screen (initGame) everything works fine, when I click the button I do indeed get the second screen, which displays all objects normally. When I click the button in the game screen I get no feedback at all, nothing happens.
What am I missing?
Thank you very much !
The problem is in this line:
btn_try = Button(game_window, text="Try!", command="clicked")
Note that the command "clicked" is inside quotaions marks and therefor a string and not the method you tried to reference. What you want is:
btn_try = Button(game_window, text="Try!", command=clicked)
I got some trouble with finding the matching if-statement to check if only one entry equals 0 of 3.
Here's the code:
def thanx(self):
if len(self.e.get()) == 0:
messagebox.showerror("Error", "Please enter affordable infos")
self.boo = False
else:
messagebox.showinfo("Submition done", "Thank you")
self.boo = True
It is only checking if my variable e equals 0, but i actually got 2 more entries. I know i could check every single one individually, however there has to be an easier way of doing this.
Im using "tkinter" btw, but this shouldnt be too much important.
I tried it with or but this isn't working or I'm doing it wrong.
(Also tried to solve this with lambda, but again just errors...)
Maybe someone can help me there...
Edit:
I might have explained this a bit confusing, I'll add the rest of the code here that you can understand this better:
from tkinter import Tk, Label, Entry, Button, W
from tkinter import messagebox
class MyForm:
def thanx(self):
if len(self.e.get()) == 0:
messagebox.showerror("Error", "Please enter affordable infos")
self.boo = False
else:
messagebox.showinfo("Submition done", "Thank you")
self.boo = True
def callback(self):
#print("Name: %s\nPassword: %s\nEmail: %s" % (self.e.get(), self.e2.get(),self.e3.get()))
if self.boo:
f = open("PrivatData.txt", "w+")
f.write("Name: %s\nPassword: %s\nEmail: %s" % (self.e.get(), self.e2.get(),self.e3.get()))
def __init__(self):
self.root = Tk()
self.root.title("Your privat details")
Label(self.root, text="Your Name").grid(row = 0, padx = 12, pady=5)
Label(self.root, text="Password").grid(row=1, padx=12, pady=5)
Label(self.root, text="Email").grid(row=2, padx=12, pady=5)
self.e = Entry(self.root)
self.e2 = Entry(self.root)
self.e3= Entry(self.root)
self.e.grid(row=0,column=1,columnspan=2)
self.e2.grid(row=1, column=1, columnspan=2)
self.e3.grid(row=2, column=1, columnspan=2)
self.e.focus_set()
self.show= Button(self.root, text="Submit", command=lambda:[self.thanx(),self.callback()])
self.quit = Button(self.root,text="Quit", command = self.root.quit)
self.show.grid(row=3, column=1, pady=4)
self.quit.grid(row=3, column=2, sticky = W, pady=4)
self.root.geometry("230x140")
self.root.configure(background= "#65499c")
self.root.mainloop()
if __name__ == "__main__":
app= MyForm()
Use any:
if any((len(self.e.get().strip())==0,len(self.e2.get().strip())==0,len(self.e2.get().strip())==0)):
do stuff to say that user did not input all fields
else:
do stuff to say that user inputted all fields
So full code:
from tkinter import Tk, Label, Entry, Button, W
from tkinter import messagebox
class MyForm:
def thanx(self):
if any((len(self.e.get().strip())==0,len(self.e2.get().strip())==0,len(self.e2.get().strip())==0)):
messagebox.showerror("Error", "Please enter affordable infos")
self.boo = False
else:
messagebox.showinfo("Submition done", "Thank you")
self.boo = True
def callback(self):
#print("Name: %s\nPassword: %s\nEmail: %s" % (self.e.get(), self.e2.get(),self.e3.get()))
if self.boo:
f = open("PrivatData.txt", "w+")
f.write("Name: %s\nPassword: %s\nEmail: %s" % (self.e.get(), self.e2.get(),self.e3.get()))
def __init__(self):
self.root = Tk()
self.root.title("Your privat details")
Label(self.root, text="Your Name").grid(row = 0, padx = 12, pady=5)
Label(self.root, text="Password").grid(row=1, padx=12, pady=5)
Label(self.root, text="Email").grid(row=2, padx=12, pady=5)
self.e = Entry(self.root)
self.e2 = Entry(self.root)
self.e3= Entry(self.root)
self.e.grid(row=0,column=1,columnspan=2)
self.e2.grid(row=1, column=1, columnspan=2)
self.e3.grid(row=2, column=1, columnspan=2)
self.e.focus_set()
self.show= Button(self.root, text="Submit", command=lambda:[self.thanx(),self.callback()])
self.quit = Button(self.root,text="Quit", command = self.root.quit)
self.show.grid(row=3, column=1, pady=4)
self.quit.grid(row=3, column=2, sticky = W, pady=4)
self.root.geometry("230x140")
self.root.configure(background= "#65499c")
self.root.mainloop()
if __name__ == "__main__":
app= MyForm()
I am assuming that at the moment you are checking if some string element equals 0.
For example
e = 'abc'
len(e) == 3 # True
l = []
len(l) == 0 # True
If you want to check if your string variable is 0 then simply:
if not self.e.get():
messagebox.showerror("Error")
self.boo = False
You may try this:
if len(self.e.get()) == 0 or len(self.e2.get()) == 0 or len(self.e3.get()) == 0:
messagebox.showerror("Error", "Please enter affordable infos")
self.boo = False
else:
messagebox.showinfo("Submition done", "Thank you")
self.boo = True
Since you have 3 variables, there's no way to check them all 'in batch' unless you build a data structure containing them and then check some conditions on that data structure. However, it does not give any advantage. If you add a new variable, say e4, you still have to add it manually to the the data structure.
To ensure that all three textboxes are not empty in one if statement, you can use the following:
if "" in [self.e.get().strip(), self.e2.get().strip(), self.e3.get().strip()]:
messagebox.showerror("Error", "Please enter affordable infos")
self.boo = False
else:
messagebox.showinfo("Submition done", "Thank you")
self.boo = True
This is a short and neat way to write what you are trying to do. This works because entry widgets will return "" if they are empty, and self.e.get().strip() makes the text returned empty (.strip() removes all whitespace at both the start and the end of the string) if it is just whitespace (" ", \t, n, etc...).
It is better to check the contents of the string rather than the length of it, because a box with just whitespace in it will not return 0, as shown below.
>>> len(" ")
1
>>> len("")
0
>>> len("\t")
1
I can't generate the number because I get the error NameError: name 'z' is not defined.
import tkinter as tk
from random import randint
def randomize():
z.set ( randint(x.get(),y.get()))
root = tk.Tk()
x = tk.IntVar()
y = tk.IntVar()
text= tk.Label(root, text = "press the button for random number")
enterX = tk.Entry(root)
enterY = tk.Entry(root)
button = tk.Button(root, text = "Press here", command=randomize)
result = tk.Label(root,text="Number is:")
number = tk.Label(root, textvariable=z)
text.pack()
enterX.pack()
enterY.pack()
button.pack()
result.pack()
number.pack()
root.mainloop()
I need help to resolve the error
You have 2 problems here.
One. You are missing z = tk.Intvar() in the global namespace.
Two. You need to assign each entry field one of the IntVar()'s.
Keep in mind that you are not validating the entry fields so if someone types anything other than a whole number you will run into an error.
Take a look at this code.
import tkinter as tk
from random import randint
def randomize():
z.set(randint(x.get(),y.get()))
print(z.get()) # added print statement to verify results.
root = tk.Tk()
x = tk.IntVar()
y = tk.IntVar()
z = tk.IntVar() # added IntVar()
text= tk.Label(root, text = "press the button for random number")
enterX = tk.Entry(root, textvariable=x) # added textvariable
enterY = tk.Entry(root, textvariable=y) # added textvariable
button = tk.Button(root, text = "Press here", command=randomize)
result = tk.Label(root,text="Number is:")
number = tk.Label(root, textvariable=z)
text.pack()
enterX.pack()
enterY.pack()
button.pack()
result.pack()
number.pack()
root.mainloop()
I have made a test Code for a school project that was assigned to the class but when i run the code the tkinter buttons load up, however when you press the button on the Maths section(the only one done), the code would crash, any help would be nice.
from tkinter import *
Window_Blank = Tk()
#Advanced Define
def MathA():
answer = input()
answer = int(answer)
print("If A=12*2 and B=15*3, What does AB-B= ")
if answer == 1035:
print("Correct")
else:
print("Incorrect")
print("The Answer was 1035")
def Math():
print(MathA())
return
def Science():
return
def Agriculture():
return
def Geographical():
return
#Basic Define
Frame1 = Frame(Window_Blank)
Frame2 = Frame(Window_Blank)
Frame3 = Frame(Window_Blank)
Frame4 = Frame(Window_Blank)
Button1 = Button(Frame1, text="Math Questions", fg="red", command=Math)
Button2 = Button(Frame2, text="Science Questions", fg="blue", command=Science)
Button3 = Button(Frame3, text="Agricultural Questions", fg="green", command=Agriculture)
Button4 = Button(Frame4, text="Geographical Questions", fg="purple", command=Geographical)
#Framework for the menu
Frame1.grid(row=0, column=0)
Frame2.grid(row=0, column=1)
Frame3.grid(row=0, column=2)
Frame4.grid(row=0, column=3)
Button1.grid(row=1)
Button2.grid(row=2)
Button3.grid(row=3)
Button4.grid(row=4)
Window_Blank.mainloop()
Change this:
def MathA():
print("If A=12*2 and B=15*3, What does AB-B= ")
answer = input()
answer = int(answer)
if answer == 1035:
print("Correct")
else:
print("Incorrect")
print("The Answer was 1035")
And:
def Math():
MathA()
return
I have some code which asks the user to enter a word they'd like to encrypt and then the program will encrypt the word and display it on a label.
I was wondering why the following code works:
import tkinter
letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
encryption_code = 'LFWOAYUISVKMNXPBDCRJTQEGHZ'
letters += letters.lower()
encryption_code += encryption_code.lower()
window = tkinter.Tk()
encryption_code_entry = tkinter.Entry(window)
entry = tkinter.Entry(window)
enc = dict(zip(letters,encryption_code))
string = 'hello world'
encr = "".join([enc.get(ch, ch) for ch in string])
def encrypt():
encrypt_label.pack()
entry.pack()
encrypt_confirm.pack()
encrypt_button.destroy()
def display_encrypt():
display_enc = encr
encrypted_label.pack()
new_message.config(text=str(display_enc))
new_message.pack()
encrypt_confirm = tkinter.Button(window, text="Confirm", command=display_encrypt)
new_message = tkinter.Label(window, text="", font=('Helvetica', 10))
encrypted_label = tkinter.Label(window, text="Your message " + entry.get() + " has been encrypted into the following: ")
encrypt_button = tkinter.Button(window, text="Encrypt", command=encrypt)
encrypt_button.pack()
encrypt_label = tkinter.Label(window, text="Please enter the message you'd like to encrypt", font=('Helvetica', 14))
window.mainloop()
But if I change string = 'hello world' (which is what I'd like to do) to string = entry.get() nothing is displayedonnew_message`. Also,
encrypted_label = tkinter.Label(window, text="Your message " + entry.get() + "has been encrypted into the following: ")
doesn't display what the user typed in the entry box so I'm almost 100% sure I'm misusing the entry.get() function.
You in fact need to have the entry.get() under display_encrypt().
Every time the encrypt_confirm button is pressed, it calls display_encrypt which will then in turn be able to get the current string in entry every time it is pressed by the user.
I edited your code a bit and it seems to be working.
Notice that I have removed string and encr as they were now redundant variables.
import tkinter
letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
encryption_code = 'LFWOAYUISVKMNXPBDCRJTQEGHZ'
letters += letters.lower()
encryption_code += encryption_code.lower()
window = tkinter.Tk()
encryption_code_entry = tkinter.Entry(window)
entry = tkinter.Entry(window)
enc = dict(zip(letters,encryption_code))
string = 'hello world'
def encrypt():
encrypt_label.pack()
entry.pack()
encrypt_confirm.pack()
encrypt_button.destroy()
def display_encrypt():
display_enc = "".join([enc.get(ch, ch) for ch in entry.get()])
encrypted_label.pack()
new_message.config(text=str(display_enc))
new_message.pack()
encrypt_confirm = tkinter.Button(window, text="Confirm", command=display_encrypt)
new_message = tkinter.Label(window, text="", font=('Helvetica', 10))
encrypted_label = tkinter.Label(window, text="Your message " + entry.get() + " has been encrypted into the following: ")
encrypt_button = tkinter.Button(window, text="Encrypt", command=encrypt)
encrypt_button.pack()
encrypt_label = tkinter.Label(window, text="Please enter the message you'd like to encrypt", font=('Helvetica', 14))
window.mainloop()
You are calling entry.get() well before the user ever has a chance to enter anything. You need to call it and reset the label in response to an event, such as the user pressing <Return>, clicking a button, etc.
