Hello everyone.. I'm a new user of python.. I have encountered a problem while trying to find the inverse of a matrix even after importing numpy and scipy. The error is:

>>> a=[[[1, 2, 3],

[2, 3, 4],

[3, 4, 5]], float]

>>> print a

[[[1, 2, 3], [2, 3, 4], [3, 4, 5]], <type 'float'>]

>>> ai=inverse(a)

Traceback (most recent call last):

File "<pyshell#7>", line 1, in <module>

ai=inverse(a)

NameError: name 'inverse' is not defined

>>> ai=numpy.inverse(a)

Traceback (most recent call last):

File "<pyshell#8>", line 1, in <module>

ai=numpy.inverse(a)

AttributeError: 'module' object has no attribute 'inverse'

Please help..
