What this means is that if you read data from your source file object, then the position you stop reading at is the position copyfileobj starts copying from.

The meanings of source and destination file parameters are similar to the previous commands, but now, they refer to objects. The length parameter is optional and represents the buffer size that is the number of bites kept in memory during the copy process.

This option can be useful when copying very large files, as it can speed up the copying process and avoids uncontrolled memory usage. As we can see, in order to use copyfileobj , we need to open the files in binary mode which is the "b" part of "rb" and "wb". In addition, the source file must be opened as readable and the destination file must be opened as writable the "r" and "w" parts, respectively.

In most if not all of the examples from here on out we provide examples that work for both Windows and Unix. The examples are different because of the shell commands used, so be sure to pay attention to how each function call is labeled in the Python comments. This method opens a pipe to or from your command.

However, note that this method was deprecated in Python 2. As an alternative, the Python documentation advises us to use methods from the subprocess module instead. Here the value returned is a file object that is connected to the pipe. This object can be read from or written to depending on the mode. The default mode is 'r', which allows reading of the file contents. Running the command in this way is exactly the same as if you ran it directly from the command line of your terminal.

This method executes the specified command in a subshell. It is available for both Unix and Windows. The syntax is as follows:. Here command is a string containing the DOS or Unix shell command.
