From “anything” to a NumPy array

Given an object a,

a=asarray(a)

converts a to a NumPy array (if possible/necessary)

Arrays can be ordered as in C (default) or Fortran:

a=asarray(a,order=’Fortran’)

isfortran(a) # returns True if a’s order is Fortran

Use asarray to, e.g., allow ﬂexible arguments in functions:

def myfunc(some_sequence):

a=asarray(some_sequence)

return 3

a-5

myfunc([1,2,3]) # list argument

myfunc((-1,1)) # tuple argument

myfunc(zeros(10)) # array argument

myfunc(-4.5) # float argument

myfunc(6) # int argument
