I'm trying to make a pygame window where I can enter and edit text. I'm following a tutorial as a base for my code but I'm getting an the following error:
Error: File "c:\Users\djwil\Documents\python\python crash course\Projects\Alien invasion\print.py", line 39, in Print
text += event.unicode
AttributeError: 'Event' object has no attribute 'unicode'
this is my code:
import pygame
from pygame.locals import *
import time
class Print:
"""Draw text to the screen."""
# text is editable with the keyboard
# options for font and background colour
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
GRAY = (200, 200, 200)
pygame.init()
screen = pygame.display.set_mode((640, 240))
# creates a screen 640 x 240 pixels in size
sysfont = pygame.font.get_default_font()
print('system font :', sysfont)
text = 'This text is editable'
font = pygame.font.SysFont(None, 24)
img = font.render(text, True, RED)
rect = img.get_rect()
running = True
background = GRAY
while running:
for event in pygame.event.get():
if event.type == QUIT:
running = False
if event.type == KEYDOWN:
if event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()
pygame.quit()

this may or may not be the problem, but event is a python class name, and you may be getting the error because you are overriding it. Bad practice at any rate.
Try using another name, like game_event or something similar

My code is now:
import pygame
from pygame.locals import *
import time
class Print:
"""Draw text to the screen."""
# text is editable with the keyboard
# options for font and background colour
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
GRAY = (200, 200, 200)
pygame.init()
screen = pygame.display.set_mode((640, 240))
# creates a screen 640 x 240 pixels in size
sysfont = pygame.font.get_default_font()
print('system font :', sysfont)
text = 'This text is editable'
font = pygame.font.SysFont(None, 24)
img = font.render(text, True, RED)
rect = img.get_rect()
running = True
background = GRAY
while running:
for event in pygame.event.get():
if event.type == QUIT:
running = False
if event.type == KEYDOWN:
if event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()
pygame.quit()and I'm still getting this error:
Error: File "c:\Users\djwil\Documents\python\python crash course\Projects\Alien invasion\print.py", line 39, in Print
text += game_event.unicode
AttributeError: 'Event' object has no attribute 'unicode'

Sorry I copied my previous code over. The code is currently:
import pygame
from pygame.locals import *
import time
class Print:
"""Draw text to the screen."""
# text is editable with the keyboard
# options for font and background colour
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
GRAY = (200, 200, 200)
pygame.init()
screen = pygame.display.set_mode((640, 240))
# creates a screen 640 x 240 pixels in size
sysfont = pygame.font.get_default_font()
print('system font :', sysfont)
text = 'This text is editable'
font = pygame.font.SysFont(None, 24)
img = font.render(text, True, RED)
rect = img.get_rect()
running = True
background = GRAY
while running:
for game_event in pygame.event.get():
if game_event.type == QUIT:
running = False
if game_event.type == KEYDOWN:
if game_event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += game_event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()
pygame.quit()This matches up with the error in my previous post

You need to make sure you are indenting correctly. As this is the entire issue.
from this:
while running:
for game_event in pygame.event.get():
if game_event.type == QUIT:
running = False
if game_event.type == KEYDOWN:
if game_event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += game_event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()to this:
while running:
for game_event in pygame.event.get():
if game_event.type == QUIT:
running = False
if game_event.type == KEYDOWN:
if game_event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += game_event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()Here is an example of a working textbox for comparison:

I think the indentation should be like this
while running:
for game_event in pygame.event.get():
if game_event.type == QUIT:
running = False
if game_event.type == KEYDOWN:
if game_event.key == K_BACKSPACE:
if len(text)>0: # if length of text is > 0
text = text[:-1] # delete the last letter in the string
else:
text += game_event.unicode
# else add the letter to the end of the string
img = font.render(text, True, RED)
rect.size=img.get_size()
cursor.topleft = rect.topright
screen.fill(background)
screen.blit(img, (20, 20))
pygame.display.update()

If you look more closely, you will find it's different
