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...
例如我们可以使用os模块的os.path.exists()方法来检测文件是否存在: importos.path os.path.isfile(fname) 如果你要确定他是文件还是目录,从 Python 3.4 开始可以使用 pathlib 模块提供的面向对象的方法 (Python 2.7 为 pathlib2 模块): frompathlibimportPathmy_file=Path("/path/to/file")ifmy_file.is_file...
If you don’t want to raise an Exception, or you don’t even need to open a file and just need to check if it exists, you have different options. The first way is using the different methods inos.path: os.path.isfile(path): returns True if the path is a valid file ...
Another way to check if a path exists (as long as you don't care if the path points to a file or directory) is to useos.path.exists. importos os.path.exists('./file.txt')# Trueos.path.exists('./link.txt')# Trueos.path.exists('./fake.txt')# Falseos.path.exists('./dir')#...
Using os.path.exists() function, Using os.path.isfile() , Using the is_file() of pathlib module, Using os.path.islink() to check file exists and is a symbolic link
