Link between two scripts on a button click in tkinter?

Question

I have two files in my directory (first.py and second.py). The first.py has a button. So on clicking the button in first.py gui window, it should be directed to second.py gui window. first.py window photo and second.py window photo. So on clicking the sign up button in the first.py, it should go to the sign up page in second.py.

How to do the connection or linking between the two scripts?

first.py

import tkinter as tk

root=tk.Tk()
root.title("My Bank")
root.geometry("500x500")

photo=tk.PhotoImage(file="image1.gif")
label = tk.Label(root, image=photo)
label.image = photo
label.pack()
label.place(x=0, y=0, relwidth=1, relheight=1)

tfm = tk.Frame(root, width=2000, height=50)
tfm.pack(side=tk.TOP)

w = tk.Label(tfm, text="MY bank", font=("Times", "24", "bold"), bg="yellow", anchor="e", fg="black", padx=350, pady=10)
w.pack(fill="both")

bfm = tk.Frame(root, width=2000, height=50, bg="gray")
bfm.pack(side=tk.BOTTOM)

w = tk.Label(root, text="Main Menu", font=("Times", "24", "bold"), bg="black", fg="white", padx=350, pady=10)
w.pack(padx=10, pady=30)

button1 = tk.Button(root, text="Sign Up", width=12, height=1, bg="black",fg="white", bd="8", font=("Helvetica", "12", "bold"))
button1.pack(padx=10, pady=10) 

button2 = tk.Button(root, text="Sign In",  width=12, height=1, 
bg="black",fg="white", bd="8",  font=("Helvetica", "12", "bold"))
button2.pack(padx=10, pady=10)

button3 = tk.Button(root, text="Admin Sign In", width=12, height=1, bg="black",fg="white", bd="8",  font=("Helvetica", "12", "bold"))
button3.pack(padx=10, pady=10)

button4 = tk.Button(root, text="Quit!",  width=5, height=1, bg="black",fg="white", bd="10",  font=("Helvetica", "12", "bold"))
button4.pack(padx=10, pady=10)

root.mainloop()

second.py

root.mainloop()

What exactly does "**it** should be directed to `second.py` gui window" mean? What happens to the first window? Have you tried writing any code, and if so, why isn't it in your question? — martineau, May 06 '18 at 19:45

I went through your problem and I guess you want to open another file when the button is clicked. To do this you need to import the file which you want to load on button click. And create another tkinter function in the external script. While running through your code i even came across the error which is tkinter.TclError: image "pyimage3" doesn't exist as of now I even fixed this for more information visit this link. Here is the code which i made all the changes.

This is a temporary script file.

For now you can just copy this and use it. I hope it helps.
