One of the simplest ways to check if a file exists in Python is by using theos.path.exists()function. This function is part of theosmodule, which provides a portable way of using operating system dependent functionality, such as reading or writing to the file system. Theos.path.exists()fun...

我们可以使用Path对象的exists()方法来判断文件是否存在。 示例代码如下所示: frompathlibimportPathdefcheck_file_exists(filename):path=Path(filename)ifpath.exists():print("文件已存在")else:print("文件不存在")# 测试文件是否存在check_file_exists("example.txt") 1. 2. 3. 4. 5. 6. 7. 8. 9....
