Python Tuples

Tuples

Tuple is a collection of ordered items separated by comma and enclosed within round brackets.

Tuples are indexed and allow duplicate items.

Unlike lists, tuples are immutable.

EntityTuple = ("Body", "Face", "Edge")
print(EntityTuple[0])

Output
Body

Use len() method to find the number of items in the tuple.

Items in the tuple cannot be changed. Add or remove items to tuples are not possible.

Delete Tuple

EntityTuple = ("Body", "Face", "Edge")
del EntityTuple

Tuple Traversal

EntityTuple = ("Body", "Face", "Edge")
for e in EntityTuple:
	print(e)

Output
Body
Face
Edge 

Check Tuple for an item

EntityTuple = ("Body", "Face", "Edge")
if "Face" in EntityTuple:
	print("Face")

Output
Face

Nested Tuple

EntityCAD = ("Body", "Face", "Edge")
EntityFEM = ("Node", "Element")
EntityTuple = (EntityCAD, EntityFEM)
print(EntityTuple)

Output
(('Body', 'Face', 'Edge'), ('Node', 'Element'))
