python - name of np array variable as string

Question

I have this code:

I restated the problem formulation somewhat. Not sure if etiquette is to post a new question. If so, my bad

import numpy as np
a = np.array([0,0])
b = np.array([1,0])
c = np.array([2,0])

my_array_list = [a,b,c]
for my_array in my_array_list:
    np.save('string_that is representative of my_array',my_array)

where 'string that is representative of my array' equals to 'a', 'b', 'c' or similar.

There is likely a better way to solve this, I can just not come up with one right now.

What is the best way to do this, fast and efficiently?

Answer 1

I can suggest you that function:

import numpy as np

def namestr(obj, namespace):
    return [name for name in namespace if namespace[name] is obj]

my_numpy = np.zeros(2)
print(namestr(my_numpy, globals()))

With output:

['my_numpy']
