Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure. It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
Python has a glob module in the standard library which performs wildcard pattern matching on filenames, [28] and an fnmatch module with functions for matching strings or filtering lists based on these same wildcard patterns. [17] Guido van Rossum, author of the Python programming language, wrote and contributed a glob routine to BSD Unix in ...
basename is a standard computer program on Unix and Unix-like operating systems. When basename is given a pathname , it will delete any prefix up to the last slash ( '/' ) character and return the result.
name – base name of the file; extension – may indicate the format of the file (e.g. .txt for plain text, .pdf for Portable Document Format, .dat for unspecified binary data, etc.) The components required to identify a file by utilities and applications varies across operating systems, as does the syntax and format for a valid filename.
If a filename contains only lowercase letters, or is a combination of a lowercase basename with an uppercase extension, or vice versa; and has no special characters, and fits within the 8.3 limits, a VFAT entry is not created on Windows NT and later versions such as XP. Instead, two bits in byte 0x0c of the directory entry are used to indicate ...
The %ComSpec% variable contains the full path to the command processor; on the Windows NT family of operating systems, this is cmd.exe, while on Windows 9x, %COMSPEC% is COMMAND.COM. %OS% The %OS% variable contains a symbolic name of the operating system family to distinguish between differing feature sets in batchjobs.
On DOS, OS/2, and Windows operating systems, the %PATH% variable is specified as a list of one or more directory names separated by semicolon (;) characters. [5]The Windows system directory (typically C:\WINDOWS\system32) is typically the first directory in the path, followed by many (but not all) of the directories for installed software packages.
