How would i change the width of the snake in my “snake game”?

Im using python and pygame:
How can i change the width of the “worm” in my game? So far the snake is only 1 pixel wide how can i change the width to be 3 or 4 pixels wide?

class Worm:
    def __init__(self, surface):
        self.surface = surface
        self.x = surface.get_width()/2
        self.y = surface.get_height()/2
        self.length = 5
        self.grow_to = 50
        self.vx = 0
        self.vy = -1
        self.body = []
        self.crashed = False
        self.color = (255, 255, 0)




    def move(self):
        """Move the worm"""
        self.x += self.vx
        self.y += self.vy

        if (self.x, self.y) in self.body:
            self.crashed = True

        self.body.insert(0, (self.x, self.y))

        if (self.grow_to > self.length):
            self.length += 1

        if len(self.body) > self.length:
            self.body.pop()

    def draw(self):
       for x, y in self.body:
           self.surface.set_at((x, y), self.color)

    def position (self):
        return self.x, self.y

    def eat(self):
        self.grow_to += 25

NEW CODE____________________________ But this causes the snake to grow continuesly

class Worm:
    def __init__(self, surface):
        self.surface = surface
        self.x = surface.get_width()/2
        self.y = surface.get_height()/2
        self.length = 5
        self.grow_to = 50
        self.vx = 0
        self.vy = -1
        self.body = []
        self.crashed = False
        self.color = (255, 255, 0)

    def move(self):
        """Move the worm"""
        self.x += self.vx
        self.y += self.vy

        if (self.x, self.y) in self.body:
            self.crashed = True

        self.body.insert(0, (self.x, self.y))
        self.body.insert(0, (self.x, self.y+1))
        self.body.insert(0, (self.x, self.y-1))
        self.body.insert(0, (self.x+1, self.y))
        self.body.insert(0, (self.x-1, self.y))

        if (self.grow_to > self.length):
            self.length += 1

        if len(self.body) > self.length:
            self.body.pop()

    def draw(self):
       for x, y in self.body:
           self.surface.set_at((x, y), self.color)
       for x, y in self.body:
           self.surface.set_at((x, y), self.color)

    def position (self):
        return self.x, self.y
        return self.x, self.y+1
        return self.x, self.y-1
        return self.x+1, self.y
        return self.x-1, self.y

    def eat(self):
        self.grow_to += 25

Answer 1

Grow it thicker with

 self.body.insert(0, (self.x, self.y))
 self.body.insert(0, (self.x, self.y+1))
 self.body.insert(0, (self.x, self.y-1))
 self.body.insert(0, (self.x+1, self.y))
 self.body.insert(0, (self.x-1, self.y))
   ...   # corner cases if they are important

draw() will automatically take in the new pixels in body. Nice game, I hacked it on Nokia PyS60 some time ago.
