class Description(*args)

Collection of strings.

Available constructors:

Description(size=0, value=’ ‘)

Description(sequence)

Parameters
sizeint, size \geq 0

sequencesequence of str

Components of the vector.

Examples

>>> import openturns as ot

Use the first constructor:

>>> ot.Description()
[]
>>> ot.Description(2)
[,]
>>> ot.Description(2, 'C')
[C,C]

Use the second constructor:

>>> vector = ot.Description(['P1', 'P2', 'P3'])
>>> vector
[P1,P2,P3]

Use some functionalities:

>>> vector[1] = 'P4'
>>> vector
[P1,P4,P3]
>>> vector.add('P5')
>>> vector
[P1,P4,P3,P5]
