Printing array without commas

[pawlaczkaj]

Hello,
I have got this output from my script:

Output:
[[1.0, 2.0, 3.0], [4.0, 5.0, 6.0], [7.0, 8.0, 9.0]] 

I want to cover it to:

Output:
[[1.0 2.0 3.0] [4.0 5.0 6.0] [7.0 8.0 9.0]]

I tried:

a = np.asarray(a)

but output is:

Output:
array([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0], [7.0, 8.0, 9.0]])

How resolve this?

---

I found that

a = np.asarray

worked correctly, but there was a problem with command print. When I used:

print ("a", a)

it gave me

Output:
('a', array([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0], [7.0, 8.0, 9.0]])

But when I used:

print a

the output was:

Output:
[[1.0 2.0 3.0] [4.0 5.0 6.0] [7.0 8.0 9.0]]

If you try to print the array as an array, it will always contain comma's because that is how python represents the array contents.
You need to create a function that loops through the array and prints without commas.
Something like:

class PrintList: def print_list(self, aname): firstitem = True if isinstance(aname, list): print('[', end='') for item in aname: if isinstance(item, list): if firstitem: firstitem = False else: print() self.print_list(item) else: print(' {} '.format(item), end='') print(']', end = '') else: print('Not a list') def tryit(): p = PrintList() p.print_list([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0], [7.0, 8.0, 9.0]]) if __name__ == '__main__': tryit()

test:

Output:
[[ 1.0 2.0 3.0 ] [ 4.0 5.0 6.0 ] [ 7.0 8.0 9.0 ]]
