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...
it is required that all the files must be present to proceed further. So, we can use functions from inbuilt python modules likeos.pathandpathlibto check file exists or not. There

os.path.exists()line returnsTrue, then another function deletes the file, the file operation coupled with ourif statementcould cause our program to crash. This sequence of events is known as arace condition. One way around this issue is by using thepathliblibrary, as seen in the next ...
Using pathlib.Path to Check if a File Exists FromPython 3.4 onwards, the pathlib module is available in your Python scripts. The pathlib module allows you to perform a whole range of tasks involving file system paths on different operating systems. For this tutorial, we will be focusing on ...
