Python文件操作：复制、删除、授权、遍历 【代码段】

1.拷贝文件夹

remove_tree(self.dest_path) # 先删除已存在的目标文件夹，否则无法复制
shutil.copytree(self.src_path, self.dest_path, dirs_exist_ok=True)

2.移除整个文件夹和文件夹下所有内容

def remove_tree():
    shutil.rmtree(self.src_root_path, onerror=self.rmtree_onerror)


def rmtree_onerror(self, func, path, exe_info):
        if os.path.isfile(path):
            os.chmod(path, stat.S_IWRITE)
            os.remove(path)
        elif os.path.isdir(path):
            os.chmod(path, stat.S_IWRITE)
            shutil.rmtree(path)

3.删除文件

if os.path.exists(src_path):
    os.chmod(src_path, stat.S_IWRITE)  # 去除只读属性，不然无法删除
    os.remove(src_path)

4.递归遍历所有文件夹

命令

python Scan_Dir.py E:\badianboke

i控制层级

import os
import sys

class Scan_Dir():
    def __init__(self, path):
        self.path = path

    def doScan(self):
        self.scanItem(self.path, 0)

    def scanItem(self, full_path, i):
        if i > 3:
            return
        if os.path.isdir(full_path):
            a = ''
            for t in range(i):
                a = a + ' '
            print(a + os.path.basename(full_path))
            list = os.listdir(full_path)
            i = i + 1
            for item in list:
                temp = os.path.join(full_path, item)
                if os.path.isdir(temp):
                    self.scanItem(temp, i)

if __name__ == '__main__':
    task = Scan_Dir(sys.argv[1])
    task.doScan()
