tkinter Entry <Return> event doesn't execute function

I’m just starting learning python and I tried to make Rock, Paper, Scissors game. However when I press Enter after filling my username – it can’t execute the function that’s the same func the ‘Play’ button executes.

def start_game():
    controller.set_user_name(input_name.get())
    frame.destroy()
    logo_label.destroy()
    name.destroy()
    input_name.destroy()
    sub.destroy()
    main_game_window()

input_name=Entry(root,font='arial 10 bold')
input_name.bind('<Return>',start_game)  
input_name.place(x=275,y=290)

sub=Button(root,text="Let's Play",font='lucida 10 bold',bg='black',fg='white',command=start_game)
sub.place(x=305,y=350)

Also the ‘computer’ picks only once, although it’s set to pick random on every round. Will be thankfull if someone gives me an advice.

import random
choices = ('Rock', 'Paper', 'Scissors')

class Player:
    def __init__(self,name='Computer',score=0, choice=random.choice(choices)):
        self.name = name
        self.score = score
        self.choice = choice
        
    def get_name(self):
        return self.name
    
    def set_name(self, name):
        self.name = name
    
    def get_score(self):
        return self.score
    
    def increase_score(self):
        self.score += 1
        
    def set_choice(self, choice=random.choice(choices)):
        self.choice = choice
        
    def get_choice(self):
        return self.choice

For the entry, although I’m not passing an argument it gives me an error

File "C:\Python310\lib\tkinter\__init__.py", line 1921, in __call__
    return self.func(*args)
TypeError: start_game() takes 0 positional arguments but 1 was given

>Solution :

You have to add ‘event’ as a parameter in your start_game() function. Modified code:

def start_game(event):
    controller.set_user_name(input_name.get())
    frame.destroy()
    logo_label.destroy()
    name.destroy()
    input_name.destroy()
    sub.destroy()
    main_game_window()

Then the start_game() function will be able to accept the Button command.
