Example 1:

import machine
import time
led = machine.Pin(2, machine.Pin.OUT)
counter = 0
while (counter < 5):
    led.on()
    time.sleep(0.5)
    led.off()
    time.sleep(0.5)
    counter += 1
print('Blinking LED is complete')

Example 2:

import machine
import time
led = machine.Pin(2, machine.Pin.OUT)
def blink_led_ntimes(num, t_on, t_off, msg):
    counter = 0
    while (counter < num):
        led.on()
        time.sleep(t_on)
        led.off()
        time.sleep(t_off)
        counter += 1
    print(msg)

Example 3:

import machine
led = machine.Pin(2, machine.Pin.OUT)
sw = machine.Pin(0, machine.Pin.IN)
while True:
    if (sw.value() == 0):
        led.on()
    else:
        led.off()
