Using time.sleep inside of a function causing syntax error

I'm trying to get started with my Raspberry Pi pico H, and I thought of a cool little project to translate text into morse code using the onboard LED to flash as dots and dashes, but to do that I need to turn the LED off at specific intervals.

I made this program to flash the LED on and off infinitely:

from machine import Pin
import time
onboardLED = Pin(25, Pin.OUT)
def LED1():
    {
        onboardLED.value(1)
    }

def LED0():
    {
        onboardLED.value(0)
    }

on = LED1
off = LED0


x = 1

while x < 2:
    on()
    time.sleep(0.1)
    off()
    time.sleep(0.1)

which works as I expected. Then, I tried to introduce 2 new functions, one for a dot and one for a dash:

from machine import Pin
import time
onboardLED = Pin(25, Pin.OUT)
def LED1():
    {
        onboardLED.value(1)
    }

def LED0():
    {
        onboardLED.value(0)
    }

on = LED1
off = LED0


def DOT():
    {
        on()
        time.sleep(1)
        off
        time.sleep(1)
    }

def DASH():
    {
        on()
        time.sleep(2.5)
        off()
        time.sleep(1)
    }
    
dot = DOT
dash = DASH

But I keep getting a syntax error for line 21, being the first time.sleep(1) within defining DOT as a function, which I assume means that there's an error using the time.sleep function within defining another function?
