how do i remove <built-in function array> from the output

Question

This below is a part of my program how do I remove the from the output of this ? can it be removed?

or is it built-in? because I intend to save it as a text file after I convert it to a 2d matrix.

Also, I want to reshape the 1D array "final" as a 2D 30*5 matrix how do I do it (of course there aren't 150 elements here still, it is yet to be added by different main loop)

edited: here stmat is an array of 80 elements and t = 8 for this particular iteration

t = n
t = int(t)
print(t)
import numpy
final = numpy.array
arr = ['1','2','3','5','7']
for p in arr :
    sum = 0 
    p = int(p)
    for j in range(t) :
        sum = sum + float(stmat[p])
        p = p + 10
    avg = sum/n
    final =  numpy.append (final, avg )
    print(avg)   
    print(final)

I get the following output

75.75
[<built-in function array> 75.75]
73.875
[<built-in function array> 75.75 73.875]
93.625
[<built-in function array> 75.75 73.875 93.625]
7.0
[<built-in function array> 75.75 73.875 93.625 7.0]
29.368750000000002
[<built-in function array> 75.75 73.875 93.625 7.0 29.368750000000002] 

Answer 1

numpy.array is a function, final = numpy.array is assigning the function itself to the variable. Calling final() now does the same thing as calling numpy.array() .

If you want to create an initial empty numpy array you should do something like final = numpy.array([]) .

Answer 2

list append is better than np.append :

final = []   # empty list
arr = ['1','2','3','5','7']
for p in arr :
    sum = 0 
    p = int(p)
    for j in range(t) :
        sum = sum + float(stmat[p])
        p = p + 10
    avg = sum/n
    final.append( avg )
    print(avg)   
    print(final)

faster and easier to use right.
