What is the usage of the path module in Python?
In Python, the path module is a sub-module of the os module that is used for manipulating file paths. It includes various methods for handling operations related to file paths, directories, and files.
Here are some commonly used methods in the path module:
- Does the path exist?
- path is a file.
- Is ‘path’ a directory?
- combines multiple paths into onepathname
- The basename of the path.
- Retrieve the directory name of the given path.
- Split the path by using the split function.
- Return a tuple of the pathname’s root and extension.
- Return the absolute path of the current directory.
- Find the size of the path.
- Determine the last modified time of a file or directory.
- Return the creation time of the specified path.
In addition, the path module also offers other methods for determining if a file is readable, writable, obtaining file access permissions, and other operations.
To use the path module, you need to first import the os module and then call the methods of the path module through os.path, for example:
import os
path = '/path/to/file.txt'
print(os.path.exists(path)) # 检查路径是否存在
print(os.path.isfile(path)) # 判断是否为文件
print(os.path.join('/path', 'to', 'file.txt')) # 组合路径
print(os.path.basename(path)) # 获取文件名
print(os.path.dirname(path)) # 获取目录部分
# ...
Above are some common methods and usage of the path module.
