TypeError：只能连接列表（不是“str”）到列表（在python 3中）

Question

我想标记包含梵文字符的jpg图像的数据集。但是我得到了类型错误。有没有人有解决这个问题。代码如下：

import matplotlib.pyplot as plt 
import glob 

direc=glob.glob('./consonants/*') 
# This line I am using to get the specific 
# folder containing devanagari character images. 

label=[] 
img_list=[] 

for i,consonants in enumerate (direc): 
    img_list=glob.glob(direc) 
    for img in img_list: 
     input_img=plt.imread(direc + '/'+ consonants + '/'+ img) 
     label.append(i) 

Answer 1

glob.glob()已经给你一个完整的路径：

import matplotlib.pyplot as plt 
import glob 

label = [] 

for i, path in enumerate(glob.glob('./consonants/*')): 
    for img in glob.glob(path): 
     input_img = plt.imread(img) 
    label.append(i)
