List

Python representation of a Maple list

Description

•	The maple.List class represents Maple objects of type list.

Method Summary

•	maple.List inherits all the methods defined on Indexable objects.

•	It implements the collections.abc.Sequence base abstract class from the collections.abc module.

•	The following methods are defined on any List object and invoke the specified implementation in Maple.

Method name	Usage	Maple implementation
index	x.index(y)	Return index of y within x
__reversed__	reversed(x)	Return iterator to traverse x in reverse order

•	Maple lists are one-based. That is, the first element of a maple.List object L is referenced as L[1]. By contrast, Python lists are zero-based.

•	A maple.List object may be transformed to a Python list using the list command.

Superclass

•

	Examples
	import maple import maple.namespace as mpl L = maple.execute('["apple", "banana", "grape", "orange"]:') L[1] # return first element mpl.combinat.choose( L, 2 ) # Convert to a Python list, equivalent to PL = ['apple', 'banana', 'grape', 'orange'] PL = list(L) PL[0] # return first element mpl.combinat.choose( PL, 2 ) # use Python list as argument
