本文实例分析了Python中os.path用法。分享给大家供大家参考。具体如下：复制代码代码如下:#coding=utf-8 import os print os.path.abspath(“d:\\new\\test.txt”) print os.path.basename(“d:\\new\\test.txt”) print os.path.dirname(“d:\\new\\test.txt”) print os.path.exists(“d:\\new”) print os.path.lexists(“d:\\new”) print os.path.expanduser(“d:\\

The `os.path` module in Python provides functions for working with file paths and directories. It includes functions for checking if a file or directory exists, joining paths together, splitting paths into their component parts, and more. Some of the commonly used functions in `os.path` module are: 1. `os.path.join()`: This function joins one or more path components into a single path. For example, `os.path.join('/usr', 'bin', 'python')` will return the path `/usr/bin/python`. 2. `os.path.exists()`: This function checks if a file or directory exists. For example, `os.path.exists('/usr/bin/python')` will return `True` if the file exists, and `False` if it doesn't. 3. `os.path.abspath()`: This function returns the absolute path of a file or directory. For example, `os.path.abspath('file.txt')` will return the absolute path of the file `file.txt`. 4. `os.path.basename()`: This function returns the base name of a file or directory. For example, `os.path.basename('/usr/bin/python')` will return `python`. 5. `os.path.dirname()`: This function returns the directory name of a file or directory. For example, `os.path.dirname('/usr/bin/python')` will return `/usr/bin`. 6. `os.path.splitext()`: This function splits a file path into its base name and extension. For example, `os.path.splitext('file.txt')` will return `('file', '.txt')`. These functions make it easy to work with file paths and directories in Python, allowing you to write more robust and flexible scripts.
