Error: TypeError: 'list' object is not callable Using turtle graphics

Question

I am attempting to code space invaders. I am doing some finishing touches however when trying to create three hearts in the top corner to represent lives I have this error: TypeError: ‘list’ object is not callable

The relevant code in main.py is:

from scoreboard import Scoreboard
scoreboard = Scoreboard()
scoreboard.lives()

In the scoreboard file the relevant lines are:

class Scoreboard(Turtle):
def __init__(self):
    super().__init__()
    self.lives = []
    self.score = 0
    self.lives_start_x = 0
    with open("High_Score.txt") as data:
        self.high_score = int(data.read())
    self.color("white")
    self.penup()
    self.update_scoreboard()
    self.hideturtle()

def lives(self):
    heart = Turtle()
    heart.penup()
    heart.goto(x=self.lives_start_x, y=0)
    heart.color('white')
    heart.hideturtle()
    heart.pendown()
    d = 10
    r = d / math.tan(math.radians(67.5))
    heart.up()
    heart.seth(45)
    heart.begin_fill()
    heart.down()
    heart.fd(d)
    heart.circle(r, 225)
    heart.left(180)
    heart.circle(r, 225)
    heart.fd(d)
    heart.end_fill()
    self.lives.append(heart)
    self.lives_start_x += 35

Any ideas?

the code in the lives function also worked fine on a separate file on it’s own while I was testing it.

Also I need to create a alien in turtle that actually look like an alien so any help with that would be appreciated as well.

Thanks

Rename the lives list so that it does not replace the lives method.

For example, you could change it to _lives:

def __init__(self):
    super().__init__()
    self._lives = []
    self.score = 0
    self.lives_start_x = 0
    with open("High_Score.txt") as data:
        self.high_score = int(data.read())
    self.color("white")
    self.penup()
    self.update_scoreboard()
    self.hideturtle()

def lives(self):
    heart = Turtle()
    heart.penup()
    heart.goto(x=self.lives_start_x, y=0)
    heart.color('white')
    heart.hideturtle()
    heart.pendown()
    d = 10
    r = d / math.tan(math.radians(67.5))
    heart.up()
    heart.seth(45)
    heart.begin_fill()
    heart.down()
    heart.fd(d)
    heart.circle(r, 225)
    heart.left(180)
    heart.circle(r, 225)
    heart.fd(d)
    heart.end_fill()
    self._lives.append(heart)
    self.lives_start_x += 35
