How to make a Splash text page with Pygame

Some little changes to make the code more usable to get this result. Now you can omit the vertical position. To put an empty line, use two commas ,,

import pygame
 
 
def render_multiline(data):
        "Shows a multiline string with text, y pos and color for each line separated by comma"
        tc = []
        for line in data.split("\n"):
 
            if line != "":
                text, height, color = line.split(",")
                if height == " " or height == "":
                    height = 0
                    if color == " " or color == "":
                        color = "red"
                else:
                    height = int(height)
                tc.append([text, height, color])
        # 2. Each list of the list above is send to write to render text
        cnt = 0
        for t, height, c in tc:
            cnt += 30
            # calls write passing the text, the vertical position and the color
            for i in t.split("\n"):
                if height == 0:
                    height = cnt
                write(i, 200, height, color=c)
                height += 30
