python - 错误“预期的字符串或缓冲区”

Question

我正在生成 2 个字符排列的图像并arabic_reshaper用于连接字符。2 个字符的 2 个排列将生成 4 个图像，但在 t1 arabic_reshaper生成错误= 请询问问题是否不清楚。 "Expected String or buffer"arabic_reshaper.reshape(word).

from bidi.algorithm import get_display
import PIL.Image, PIL.ImageFont, PIL.ImageDraw
import arabic_reshaper

unicode_text = u"\u06F1"+ u"\u06CC"+ u"\u06A9"
list_of_letters = list (unicode_text)
folder = 1
n=2
for i in range(1,n+1):
    for word in itertools.permutations( list_of_letters,i):
        print word
        t1 =  arabic_reshaper.reshape(word)
        print t1
        img= PIL.Image.new("L", (200, 200))
        draw = PIL.ImageDraw.Draw(img)
        font = PIL.ImageFont.truetype( r"C:\Users\arabtype.ttf", 40)
        t2 = get_display(t1)      
        print t2# <--- here's the magic <---
        draw.text( (10,50), ' ' + t2, fill=220, font=font)
        img.show()

问题是itertools.permutations产生一个元组。

您需要将其转换为字符串。像这样的东西：

for word in itertools.permutations( list_of_letters,i):
    word = u''.join(word)
    print word
