使用 os.walk 从每个目录中获取第一个文件

Question

I am using the following code to extract all files (with same type) in all subdirectories in parent folder.

dcm_files = []
for root, dirs, files in os.walk(path):
    for names in files:
        if names.endswith(".dcm"):
            dcm_files.append(os.path.join(root, names))

How do I only get the first file from each subdirectories in parent folder ?

Answer 1

1. you find all the files
2. you index the first file from that list files[0]
