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 连接字符。 2 个字符的 2 排列将生成 4 个图像，但 arabic_reshaper 在 t1 = arabic_reshaper.reshape(word).
处生成错误 "Expected String or buffer" 请询问是否问题不清楚。

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:\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()

Answer 1

问题是 itertools.permutations 产生了一个元组。

您需要将其转换为字符串。像这样：

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

错误 "expected string or buffer"
