print(path, type(path)) Output: C:\temp\tempFile.txt We used the Path() constructor to convert String to Path. This constructor accepts a string that contains a required path and converts the string to a POSIX path or a Windows path based on your system. In terms of OS, a path...

from pathlib import Path path = Path.home() / "main.py" This ensures that your code will continue working on different operating systems. Here’s what the resulting path variable will evaluate to on Windows and on a Unix-like system compliant with the POSIX standard: Windows: WindowsPath(...
在现代版本的 Python 中,os.listdir()的替代方法是使用os.scandir()和pathlib.Path()。 os.scandir() 是在 Python 3.5 中引入的,并在 PEP 471 中有记录。os.scandir()在调用时返回一个迭代器(iterator)而不是列表: >>> import os>>> entries = os.scandir('my_directory/')>>> entries<posix.Scandir...
path.join(basepath, entry)): print(entry) Here, the call to os.listdir() returns a list of everything in the specified path, and then that list is filtered by os.path.isfile() to only print out files and not directories. This produces the following output: Shell file1.py file3...
