错误"expected string or buffer"

Question

我正在生成2个字符排列的图像，并使用arabic_reshaper来连接字符。2个字符的2个置换将生成4个图像，但arabic_reshaper在T1 = arabic_reshaper.reshape(word).
生成错误"Expected String or buffer"请询问问题是否不清楚。

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:Usersarabtype.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产生元组。

您需要将其转换为字符串。这样的东西：

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