Python common directory operations

Python3 common directory operations

    #导入os模块
	import os

	# 创建目录
	os.mkdir('E:\\PythonProject\\testdir')

	# 删除目录
	os.rmdir('E:\\PythonProject\\testdir')

	# 创建多级目录
	os.makedirs('E:\\PythonProject\\testdir\\testdir2')
	
	# 删除多级目录
	os.removedirs('E:\\PythonProject\\testdir\\testdir2')
	
	# 获取目录下文件夹及文件
	path = os.listdir('E:\\PythonProject')
	for ep in path:
    	print(ep)
    	
	# 获取当前目录位置`在这里插入代码片`
	print(os.getcwd())
	
	# 切换目录
	os.chdir('E:\\360Downloads')
	print(os.getcwd())
	
	# 遍历所有子目录以及文件
	for parent,dirnames,filenames in os.walk('E:'+os.sep+'PythonProject'):
    	for filename in filenames:
        	file_path=os.path.join(parent,filename)
        	print(file_path)
