Hi,

I have a problem with the Numpy module, but I think it is a very basic issue
for many of you...
I have a file with numerical data (2 columns, and 5 lignes) as :
1 2
3 4
... ...

And I woulid like to convert it in a matrix as :
[[1,2]
[3,4]
...]

My python script is :

fic=open('file.txt','r')
ligne=fic.readlines()
fic.close()

m=numpy.array(ligne)

and I get :
['1,2\n' '3,4']

So I cannot call m[0][0]...

Even if I modify my text file with :
[[1,2],
[3,4]
...]

I get :

['[[1,2],[3,4]]'] and I cannot call m[0][0].

Thank you very much for your help,


Clo
