今天开始接触到了文件目录、路径方面的知识点。记录如下
先看代码
#!/usr/bin/python # -*- coding: utf-8 -*- import os import sys current_path = os.getcwd() path_test = "/home/zhangshuli/PROJECT/PROJECTL/32_kk" path_test2 = "/home/zhangshuli/PROJECT/PROJECTL/32_kk/packages/apps/Calculator" print(current_path) os.chdir(path_test) print(current_path) current_path = os.getcwd() print(current_path) current_path = os.listdir(path_test) print(current_path) current_path = os.path.split(path_test) print(current_path) os.chdir(path_test2) current_path = os.path.abspath(os.curdir) print(current_path) os.chdir(path_test2) current_path = os.path.abspath(‘.‘) print(current_path) current_path = os.path.abspath(‘..‘) print(current_path) current_path = sys.argv[0] print(current_path)
运行结果如下
/home/zhangshuli/desktop/python_test /home/zhangshuli/desktop/python_test /home/zhangshuli/PROJECT/PROJECTL/32_kk [‘ndk‘, ‘makeMtk.ini‘, ‘mediatek‘, ‘bionic‘, ‘dalvik‘, ‘libcore‘, ‘vanzo_custom_base‘, ‘bootable‘, ‘hardware‘, ‘mbldenv.sh‘, ‘system‘, ‘mk‘, ‘external‘, ‘makeMtk‘, ‘Makefile‘, ‘checkenv.log‘, ‘packages‘, ‘apks‘, ‘out‘, ‘development‘, ‘recommend_apks‘, ‘pdk‘, ‘r1.txt‘, ‘auto_sync_android.log‘, ‘art‘, ‘sdk‘, ‘abi‘, ‘docs‘, ‘libnativehelper‘, ‘log‘, ‘kernel‘, ‘update_overlay_files.py‘, ‘.repo‘, ‘frameworks‘, ‘device‘, ‘vanzo_common2.pyc‘, ‘build‘, ‘vendor‘, ‘vanzo_common2.py‘, ‘prebuilts‘] (‘/home/zhangshuli/PROJECT/PROJECTL‘, ‘32_kk‘) /home/zhangshuli/PROJECT/PROJECTL/32_kk/packages/apps/Calculator /home/zhangshuli/PROJECT/PROJECTL/32_kk/packages/apps/Calculator /home/zhangshuli/PROJECT/PROJECTL/32_kk/packages/apps /home/zhangshuli/desktop/python_test/path.py
相关知识点总结：
1.os.chdir("path"):切换到path目录
2.os.getcwd():获得当前工作目录
如果你使用os.chdir()切换了目录，os.getcwd()会跟着改变
3.os.path.split(path_test)：把path_test进行拆分，得到的是当前目录名跟它的父类路径
4.os.path.abspath(os.curdir)：获得当前工作路径
也可以使用这个方法
os.path.abspath(‘.‘)
. 代表当前路径
5.os.path.abspath(‘..‘)：获得当前目录的父目录路径
..代表上一级目录
6.sys.argv[0]：获得运行脚本你本身所在的目录。
