I will attempt to create suggested test cases but as I am not the most familiar with Python's unit test framework it might take me some time, I estimate as long as. Nothing exists for the use case destination is a directory as described in the original bug. Inside of Lib/test/test_os.py is a class FileTests that contains a single function test_rename which seems to only check to make sure that the reference count for the first argument is not mis-handeled. Over the weekend I verified the test cases are incomplete for Python 3.4. I have not worked with test suite but I will do my best. Thanks for the feedback! Over the weekend I will make sure the documentation and test cases cover all possibilities. I count 2*3*2=12 possibilities to check (excluding src and dst being on different filesystems):ĭst: file, empty directory, or non-empty directoryĪlso, do we have tests for all of these scenarios before we document it?

This might not be the best phrasing so please feel free to offer alternatives.Ĭhris, maybe you can guess better wording?Īuthor: Chris Jerdonek (chris.jerdonek) *īefore we discuss wording, it's not clear to me whether all possibilities have been checked.

I have attached a Python 3.4 patch for consideration. On Windows, if dst already exists, OSError will be raised even if it is a file." If successful, the renaming will be an atomic operation (this is a POSIX requirement). The operation may fail on some Unix flavors if src and dst are on different filesystems. On Unix, if src is a directory and dst is a file NotADirectoryError will be raised. On Unix, if dst exists and is a file, it will be replaced silently if the user has permission and src is a file. If dst is a directory that is not empty, OSError will be raised. "Rename the file or directory src to dst. Indeed os.rename does not exhibit the same behavior as the documentation describes.įor Python 3.4 here is the fix I came up with: (Actually if the source is a directory the inverse is true if dst is a file, OSError will be raised.) If the source is a directory and the destination is an empty directory, it'll overwrite the former with the latter. os.rename's documentation says "If dst is a directory, OSError will be raised". First, go to the folder where the file is located (e.g., “Files_To_Rename”) and click on the file path (see image below) It should look something like “C:\Users\erima96\Documents\Files_To_Rename”.Improve os.rename documentation and testsĭavid.Benjamin, Todd.Rovito, asvetlov, benjamin.peterson, chris.jerdonek, lotti, loewis, terry.reedyĬreated on 17:36 by David.Benjamin, last changed 21:46 by orsenthil. If we use Windows, we can open up the File Explorer. That is, if we store our Python scripts (or Jupyter notebooks) in certain directories, we need to tell Python the complete path to the file we want to rename. That is, step 1 is finding the location of the file we want to change the name on. Getting the File Path of the File we Want to Rename With Pythonįirst, to get Python to rename a file Python needs to know where the file is located.

In the renaming a file in Python examples below, we will learn how to carry on and changing names both in Linux and Windows. However, how we go about in the first step to rename a file in Python may differ depending on which OS we use. Now, the general procedure is similar when we are using Linux or Windows. In the first section, we are going to learn how to rename a single file in Python step-by-step.
