[LabPython-Users] A question from a beginner

Hi ，everyone!
I'm just a student ans this is my first time to use python and Labpython, but I meet a trouble so I ask for some help.
I use a software package "igraph" in python .There is an igraph's own namespace summary()  ,when I command this,some information shows like this:

>>> summary(g)
6 vertices, 6 edges, undirected
Number of components: 2
Diameter: 1
Density: 0.4000
Average path length: 1.0000
print also shows some information:
>>> print g
Undirected graph (|V| = 3, |E| = 2)In labpython,I can do it  to show the information that "print g" give as string




But I can't find the way to use "summary(g)"
Would you please help me ?
Many thanks!
