1、os.path模組

# os.path常用方法

from os import path
p=path.join('/etc','sysconfig','network')  # 路徑拼接
print(type(p),p)
print(path.exists(p)) # 判斷路徑是否存在

print(path.split(p)) #  將路徑切割為2部分，head，tail

print(path.abspath('.')) # 當前路徑的絕對路徑

p=path.join('o:/',p,'test.txt')
print(p)  # o:/etc\sysconfig\network\test.txt
 

print(path.dirname(p)) # o:/etc\sysconfig\network
print(path.basename(p)) # test.txt

p1=path.abspath(__file__)
while p1 != path.dirname(p1):
    p1=path.dirname(p1)
    print(p1,path.basename(p1))
    
'''
執行結果：
F:\study-python\com.lx.study\week7 week7
F:\study-python\com.lx.study com.lx.study
F:\study-python study-python
F:\

2、pathlib模組

# python3.4版本引入pathlib模組，提供Path物件來操作，包括目錄和檔案；
