在GraphWin中键入效果

我尝试在窗口中创建文本输入效果,但是它出现了 " TypeError:' Text'对象不可迭代"。这是我目前的代码:

from graphics import *
import sys
from time import sleep

window = GraphWin('Test', 1000, 700)

text = Text(Point(500, 150), "This is just a test :P")
words = ("This is just a test :P")
for char in text:
    sleep(0.1)
    sys.stdout.write(char)
    sys.stdout.flush()
word.draw(window)

Source for typing effect

如果我使用'单词'那么文本会出现在shell中。变量,但如果我尝试使用文本变量,则变为TypeError。有没有办法让它可迭代?

首先,您混淆并混淆变量textwords;第二,你的Text对象不可迭代,但你可以创建几个连续显示的对象,同时迭代`words'

from graphics import *
import sys
from time import sleep

window = GraphWin('Test', 1000, 700)

text = Text(Point(500, 150), "This is just a test :P")
words = "This is just a test :P"

# this prints to console
for char in words:
    sleep(0.1)
    sys.stdout.write(char)
    sys.stdout.flush()

# that displays on canvas
for idx, t in enumerate(words):
    text = Text(Point(300+idx*20, 150), t)
    text.draw(window)
    sleep(0.1)

python 3 中,您可以使用标准sys.stdout来电替换print的来电:

# this prints to console
for char in words:
    sleep(0.1)
    print(char, end='', flush=True)
