Examples

In [1]:

import vcsn
label = vcsn.context('law_char, q').label

Instead of a.multiply(b), you may write a * b.

In [2]:

label('ab') * label('cd')

Out[2]:

$\mathit{abcd}$

In [3]:

label('ab').multiply(label('cd'))

Out[3]:

$\mathit{abcd}$

In [4]:

label('ab') * label(r'\e')

Out[4]:

$\mathit{ab}$

Instead of a.multiply(3), you may write a ** 3.

In [5]:

label('ab') ** 0

Out[5]:

$\varepsilon$

In [6]:

label('ab') ** 1

Out[6]:

$\mathit{ab}$

In [7]:

label('ab') ** 3

Out[7]:
