用python 遍历文件夹中所有.dcm文件

import dicom
import os

def eachFile(filepath):
    for file in os.listdir(filepath):
        child = os.path.join(filepath, file)
        if(os.path.isdir(child)):
            eachFile(child)
        else:
            if os.path.splitext(child)[1] == ".dcm":
                # print(child)
                ds = dicom.read_file(child)
                print(ds.UID)
