Tkinter While loop int issue

Question

import time
from tkinter import* 

start_value=Entry(root,width=10)
start_value.pack()
start_value.get()

while int(start_value.get())<100:
   int(start_value.get()) += 1

Because of the int(start_value.get()) += 1 on this code my loop doesn’t work.

Answer 1

the issue arises from the fact that you are creating an Entry, which you are assigning as an empty string. So, when you try to convert start_value into an int, you are trying to convert an empty string into an int, hence the error. You can fix this by setting the initial value of the entry to 0 (or whatever int you want), incrementing that value, deleting the initial value, and then reinserting the new value. I have provided an example of the entry value incrementing on its own until it reaches 100.

import time
from tkinter import* 

root = Tk()

start_value=Entry(root,width=10)
start_value.pack()
start_value.insert(0, 0)

def increase_value():
    value = int(start_value.get())
    value += 1
    start_value.delete(0, 'end')
    start_value.insert(0, value)

    if value < 100:
        # increase the value every 100 milliseconds
        root.after(100, increase_value)

increase_value()

root.mainloop()

    loop_number=int(end_value_int) + 1
    loop_total= int(start_value_int)
    
    while int(loop_number) > int(loop_total) :
        print("NFT_" +str(loop_total) + " generated")  
        loop_total += 1 




start_value=Entry(root,width=10)
start_value.pack()

end_value=Entry(root,width=10)
end_value.pack()

#loop_number =  
collection_name=Entry(root,width=10)
collection_name.pack()
price=Entry(root,width=10)
button1=Button(root,text="Start",command=buttonclick12)
button1.pack()
loop_total = 0
