ValueError when checking if variable is None or numpy.array

Question

I\'d like to check if variable is None or numpy.array. I\'ve implemented check_a function to do this.

def check_a(a):
    if not a:
        prin         


        

Answer 1

You can see if object has shape or not

def check_array(x):
    try:
        x.shape
        return True
    except:
        return False
