cmath.cosh(x) Return the hyperbolic cosine of x.

InteractiveInterpreter.showtraceback() Display the exception that just occurred. We remove the first stack item because it is within the interpreter object implementation. The output is written by the write() method. Changed in version 3.5: The full chained traceback is displayed instead of just the primary traceback.

turtle.update() Perform a TurtleScreen update. To be used when tracer is turned off.

gc.collect(generations=2) With no arguments, run a full collection. The optional argument generation may be an integer specifying which generation to collect (from 0 to 2). A ValueError is raised if the generation number is invalid. The number of unreachable objects found is returned. The free lists maintained for a number of built-in types are cleared whenever a full collection or collection of the highest generation (2) is run. Not all items in some free lists may be freed due to the parti

InteractiveInterpreter.showsyntaxerror(filename=None) Display the syntax error that just occurred. This does not display a stack trace because there isn’t one for syntax errors. If filename is given, it is stuffed into the exception instead of the default filename provided by Python’s parser, because it always uses '<string>' when reading from a string. The output is written by the write() method.

is_reserved

window.redrawwin() Touch the entire window, causing it to be completely redrawn on the next refresh() call.
