    Files are searched relative to the working directory, rather than from the root directory. At logon, the user's working directory is set to their home directory; it can be set afterwards by using a command.

    Python's standard library includes heapq.nsmallest and heapq.nlargest functions for returning the smallest or largest elements from a collection, in sorted order. The implementation maintains a binary heap , limited to holding k {\displaystyle k} elements, and initialized to the first k {\displaystyle k} elements in the collection.

  8. File URI scheme - Wikipedia

    en.wikipedia.org/wiki/File_URI_scheme

    A valid file URI must therefore begin with either file:/path (no hostname), file:///path (empty hostname), or file://hostname/path. file://path (i.e. two slashes, without a hostname) is never correct, but is often used. Further slashes in path separate directory names in a hierarchical system of directories and subdirectories. In this usage ...

    The file can then be allocated as contiguous disk blocks. In that case, to convert the file block address into a disk block address, the operating system simply adds the file block address to the address of the first disk block constituting the file. The scheme is simple, but the file cannot exceed its created size.
