This method copies the content of a source file into a destination file, from the current source-file position. However, you may have noticed the creation date was preserved on the new file, unlike with py, which copied "file1.txt" to "file3.txt" and gave it a new creation date. rw-r-r- 1 scott staff 6 Oct 27 11:27 file4.txtĪs we can see from executing our code above, "file1.txt" was copied to "file4.txt". rw-r-r- 1 scott staff 6 Oct 27 11:29 file3.txt rw-r-r- 1 scott staff 6 Oct 27 11:27 file1.txt rw-r-r- 1 scott staff 91 Oct 27 11:26 copy-files.py The syntax is as follows: py2(src_file, dest_file, *, follow_symlinks= True)Īgain, these parameters are the same as in the previous commands we've mentioned so far.įor example, the following code will copy "file1.txt" into "file4.txt", as well as preserve the metadata of the original file, "file1.txt". If the platform doesn't allow for full metadata saving, then copy2 doesn't return failure and it will just preserve any metadata it can. copy2Īs with the previous methods, copy2 method is identical to the copy method, but in addition to copying the file contents it also attempts to preserve all the source file's metadata. If you do, then you'll get an error when trying to import that module due to a circular import problem. Note: Make sure you don't name your script the same as one of the module you're importing (which I mistakenly did when testing code for this article). For example, the following code will copy "file1.txt" into "file3.txt". The syntax is as follows: py(src_file, dest_file, *, follow_symlinks= True)Įach of these parameters are the same as in the copyfile method. Copying file permissions is not a trivial task in most programming languages, so this is a nice feature to have. This method is very similar to copyfile, with the main difference being that in addition to copying the content of the source file, it goes one step further and also copies the file's file system permissions. If it is set to False, and the source file is a symbolic link, then instead of copying the file, a new symbolic link will be created. One interesting and potentially useful feature of pyfile is the follow_symlinks Boolean argument. The syntax for this method is: pyfile(src_file, dest_file, *, follow_symlinks= True)įor example, the following code will copy a file named "file1.txt" into a file named "file2.txt": If the destination file already exists, it will be replaced with the newly copied file. If the names are the same then it will generate an error. The destination provided to it must be a writable file, and have a different name than the source file. This method copies the content of one file into another file. The shutil module offers several high level methods to copy files. You'll notice that many of these methods, in both the shutil module and the os module, have very similar functionality (which shouldn't be surprising), but each varies in functionality from each other very slightly, which I'll explain as well. All of the os methods we show here are methods that allow us to execute shell commands from our Python code, which we'll use to execute the copy command (Windows) or the cp command (Unix). When it comes to using Python to copy files, there are two main ways: using the shutil module or the os module.
