OS
https://docs.python.org/3/library/os.html
walk 第一个参数是目录, 后面是目录下的目录名和文件名
~/g/python-reference/test/组目录 $ tree
.
└── 父目录
├── 父文件1
└── 目录
├── 叶子文件1
└── 叶子文件2
('.', ['父目录'], [])
('./父目录', ['目录'], ['父文件1'])
('./父目录/目录', [], ['叶子文件2', '叶子文件1'])
基础
os.getcwd() # 获取当前目录
os.path.abspath('.')
os.path.isdir("<path>") # 是否是目录
os.chdir('Pictures') # 切换目录
os.listdir() # 遍历文件
import shutil
shutil.rmtree('<directory>') # 删除目录
[ ] os.chroot(path)
os.fchdir(fd)
等于os.chdiros.getcwd()
返回当前工作目录:'/home/wangx/github/python-reference'os.getcwdb() 返回当前工作目录的二进制:
b'/home/wangx/github/duishang_design/\xe7\xbd\x91\xe9\xa1\xb5'os.listdir(path=".") Return a list containing the names of the entries in the directory given by path.
os.scandir(path=".") Better performance than os.listdir
filter(lambda x: x.is_dir(), os.scandir()) # show all the directory entry
os.path
os.path.abspath
[ ]
os.path.dirnameos.path.exists返回是否存在这个文件或者目录[ ]
os.path.lexistsos.path.isfile:
Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.
