Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.
The turtle moves with commands that are relative to its own position, LEFT 90 means spin left by 90 degrees. Some Logo implementations, particularly those that allow the use of concurrency and multiple turtles, support collision detection and allow the user to redefine the appearance of the turtle cursor, essentially allowing the Logo turtles ...

reStructuredText (RST, ReST, or reST) is a file format for textual data used primarily in the Python programming language community for technical documentation.. It is part of the Docutils project of the Python Doc-SIG (Documentation Special Interest Group), aimed at creating a set of tools for Python similar to Javadoc for Java or Plain Old Documentation (POD) for Perl.
The biggest difference between the two is the location of the braces: in the GNU style, opening and closing braces are on lines by themselves, with the same indent. BSD style places an opening brace at the end of the preceding line, and the closing braces can be followed by else. The size of indent and location of whitespace also differs.

[citation needed] For input/output (I/O), text may be written to the command window (output stream) using print and to the graphics window using label. Animations require both the ability to draw and to erase shapes. The process is the same, except that in the former, a line is deposited on the display device and in the latter a line is removed.
Turtle carapaces and scutes from Red Sea turtles (Eretmochelys imbricata) were used in rings, bracelets, dishes, bowls, knife hilts, amulets, and combs. Carapaces from Kleinmann's tortoise were used as sounding boards for lutes, harps and mandolins. [16] Turtle shells were also used to make norvas, an instrument resembling a banjo. [26]
