Python tkinter Entry Function not saving input into variable-CodePudding

I am trying to use tkinter to have a user input variables to pass it into a function. The problem is , the input from the user is not being assigned to the actual variable for whatever reason.

root = Tk()
root.geometry("600x300")


MainWindow = Label(root, text = "Input var:")
MainWindow.grid(row=0, column = 0)
var= Entry(root)
var.grid(row=0, column=1)

I have about 20 variables being asked for in the GUI that has similar code to the above.

I then assign a button to display what is assigned to the variable (for troubleshooting purposes, the original purpose of the button is to pass the variables into a function).

buttonGo=Button(root, text="Generate", command= lambda: print(f'Var is : {var}'))
buttonGo.grid(row=20, column=1)
buttonExit
buttonExit.grid(row=20, column=2)    

root.mainloop()

When I run the program and click on the "Generate" button, I get the below output and not what I define it in the program.

Var is : .!entry

CodePudding user response：

That .!entry is the widget, not the value. If you want the value, you need to use the get() method of the widget.

In other words, something like:

value = var.get()
# Now use value.

CodePudding user response：

Based on the replies I got, I believe I found the answer to be using .get method when calling the function. I modified the line to:

buttonGo=Button(root, text="Generate", command= lambda: print(f'Var is : {var.get()}'))

Thanks for the replies and explanations.
