Python学习week7-文件路径操作

Posted 2021-01-13 soulgou

1、os.path模块

# os.path常用方法

from os import path
p=path.join(‘/etc‘,‘sysconfig‘,‘network‘)  # 路径拼接
print(type(p),p)
print(path.exists(p)) # 判断路径是否存在

print(path.split(p)) #  将路径切割为2部分，head，tail

print(path.abspath(‘.‘)) # 当前路径的绝对路径

p=path.join(‘o:/‘,p,‘test.txt‘)
print(p)  # o:/etcsysconfig
etwork	est.txt
print(path.dirname(p)) # o:/etcsysconfig
etwork
print(path.basename(p)) # test.txt

p1=path.abspath(__file__)
while p1 != path.dirname(p1):
    p1=path.dirname(p1)
    print(p1,path.basename(p1))
    
‘‘‘
运行结果：
F:study-pythoncom.lx.studyweek7 week7
F:study-pythoncom.lx.study com.lx.study
F:study-python study-python
F: 
‘‘‘

2、pathlib模块

# python3.4版本引入pathlib模块，提供Path对象来操作，包括目录和文件；
