测试1(直接把B文件夹移动到了A里，成为了A的子文件夹)

import os
import shutil
 
# 移动文件夹,B文件夹在当前目录没有了，跑到了A的子文件里
##
shutil.move('./example1/B/', './example1/A/')

测试2(B文件不动，将B文件里的所有的子文件夹移动到A内）

import os
import shutil

def move_folder(source_folder, destination_folder,overlapp=False):
  # 创建目标文件夹
    os.makedirs(destination_folder, exist_ok=True)
    
    destFileFolder = os.listdir(destination_folder)
    # 遍历源文件夹中的所有文件和文件夹
    for subFileFolder in os.listdir(source_folder):
        print(subFileFolder)
        source_item = os.path.join(source_folder, subFileFolder)
        if(subFileFolder in destFileFolder):
            if(not overlapp):
                print("原始文件夹{}不移动!!!".format(source_item))
            else:
                # 把原始的文件给删除，然后再移动
                print("未实现，应该首先把这个结果给删除点，然后复制过来。。。。")
        else:
            shutil.move(source_item, destination_folder)
            print("{}-->移动-->{}完成！！！".format(source_item,destination_folder))
# 示例用法

# delete_list
file_path ='./example2/A/'
file_list = os.listdir(file_path)
# 从文件夹中删掉
if(".DS_Store" in file_list):
    print("There is .DS_Store in filefolder, delete it!!!")
    file_list.remove(".DS_Store")
    os.remove(file_path+"/.DS_Store")
else:
    print("No .DS_Store in file folder")


move_folder("./example2/B/","./example2/A/")

结果如下

移动子文件夹

import pickle 
import os 
import shutil
read_path="/Users/yxk/Desktop/核磁项目/527检查修改mask/ThreeD_patient_list.pkl"
base_sample_path = "/Volumes/My Passport/yxk_move_sample/file/"
with open(read_path,"rb") as f:  # Python 3: open(..., 'rb')
    ThreeD_patient_list=pickle.load(f)
    
print(ThreeD_patient_list)

for patient in ThreeD_patient_list:
    shutil.move(base_sample_path+patient,"/Volumes/My Passport/yxk_move_sample/ThreeDT1样本/")
