This can be done using a lambda, like so:
button = Tk.Button(master=frame, text='press', command= lambda: action(someNumber))
This is a simple way to bind the argument without an explicit wrapper method or modifying the original action.

This can also be done by using partial from the standard library functools, like this:
from functools import partial
#(...)
action_with_arg = partial(action, arg)
button = Tk.Button(master=frame, text='press', command=action_with_arg)

How to use a Tkinter button (call a function) that has an argument?
You can do this with lambda or partial. But not in this case, because you've misdignosed the problem. You need to make the entry an instance variable, then you will be able to access it from the method without passing it. class newTopLevel(object): def __init__(self, root): self.newWindow = Toplevel(root) self.entry_1 = tk.Entry(self.newWindow) # <==change here self.entry_1.grid(row=0, column=1) self.newWindow.btn = tk.Button(self.newWindow,text='Enter',command=self.fun) self.newWindow.btn.grid(row=0,column=2) def fun(self): get_value=self.entry_1.get() More on reddit.com

November 8, 2019Buttons with same parameters
Sorry, there is no params= argument for tkinter buttons. All you have is the command= argument. It is possible to pass arguments to the function specified in the command= argument, as explained here . There are complications than can arise depending on the command arguments you pass, so maybe you can give a small example of what you want to pass, More on reddit.com

March 31, 2022Tkinter button command using lambda to call a class method - how???
command=self.open_notebook will work, and is a better than using lambda in my opinion. You also need to move most of the code under def __init__ rather than where it is. class MainWidget: def __init__(self): root = Tk() root.geometry("400x400") search_frame = Frame(root) search_frame.pack() self.search_function = SearchFunction(search_frame) open_notebook_button = Button(root, text="Open", command=self.open_notebook) open_notebook_button.pack() root.mainloop() def open_notebook(self): self.search_function.get_emp_id() # and more stuff to add later More on reddit.com

r/learnpython on Reddit: How to use a Tkinter button (call a function) that has an argument?
November 20, 2020 -
Hello everyone,
I have a Tkinter window that is defined in a class, and I have a function that gets a value from the Tkinter window.
I.E.
class newTopLevel(object):
def __init__(self, root):
self.newWindow = Toplevel(root)
entry_1 = tk.Entry(self.newWindow).grid(row=0, column=1)
self.newWindow.btn = tk.Button(self.newWindow,text='Enter',command=self.fun)
self.newWindow.btn.grid(row=0,column=2)
def fun(self):
get_value=entry_1.get()The issue here is entry_1 is not defined in my function. I normally don't have my Tkinter within a class, thus its a global and its properties (such as buttons and entry grids) are globals and they don't have to be defined. However in this case, now it does need to defined. I tried this:
def fun(self,entry_1):
get_value=entry_1.get()However, then I cannot use the button command to call it.
self.newWindow.btn = tk.Button(self.newWindow,text='Enter',command=self.fun(entry_1))
If I don't include the argument entry_1, then I'll get an error that fun has an argument and I haven't given any when using the button. I don't quite know how to use a Tkinter button that has arguments. Any help would be greatly appreciated!

r/learnpython on Reddit: Buttons with same parameters
March 31, 2022 -
Happened to just stumble across this sub while looking for an answer that I can not find. Hopefully I can get an answer.
I've been working with python on and off for a while now. Trying to make a program with Tkinter. I have multiple buttons that I'm trying to place but I want all the parameters to be the same.
The code looks like this (don't post often so not sure how to do the code thing)
params= { 'font'= ('Courier', 10), 'width'= 15, 'height'= 5, }
tk.button(text='new button', command, params)
I know usually when passing multiple parameters I can just do params = params and all is good. Its not working with the buttons. Anything I look up tells me how to do multiple commands or multiple arguments in the command. Am I on the right track or am I missing something?
