  lcd_string("SENTENCE ONE",2) 
  lcd_byte(LCD_LINE_2, LCD_CMD)
  lcd_string("SENTENCE TWO",2)
  lcd_byte(LCD_LINE_3, LCD_CMD)
  lcd_string("SENTENCE THREE",2)
  lcd_byte(LCD_LINE_4, LCD_CMD)
  lcd_string("SENTENCE FOUR",2)    

Answer 1

Not tested , but i guess it should help you get started

import time

def typewriter_like(sentence, lcd_line, delay=1):
    for i,letter in enumerate(sentence):
        lcd_byte(lcd_line, LCD_CMD)
        lcd_string(sentence[:i+1], 2)
        time.sleep(delay)


# Use it
typewriter_like("Sentence One", LCD_LINE_1)
