recursion not working for me

So I am working with numpy and I've been asked to create a function that returns the input "grades of students" as the average of the grades in a map without the use of a loop, and the only thing that came to my mind to make this possible is recursion 

def hw_grade_average(_array):
   condition=len(_array)
   stop=condition
   start=0
   outp=[]
   def calc(inp):
      if stop-1==inp:
           return outp
       if stop!=inp:
           calc=float(sum(_array[start]))/float(len(_array[start]))
           outp.append(calc)
       return calc(inp+1)
    _returned = np.asarray(outp,dtype=float)
    return calc(start)

in input for an example 

hw_grade_average(hw_grades)

where 

    hw_grades=
           array([[ 57,  99, 100,  81,  77],
                  [ 70,  91,  57,  77,  56],
                  [ 74,  89,  62, 100,  99],
                  [ 61,  53,  42,  65,  21],
                  [ 81,  65,  40,  37,  60],
                  [ 75,  88, 100,  92,  95]])

The output I am looking for is

array([82.8, 70.2, 84.8, 48.4, 56.5, 90. ])

but I get that an

TypeError: 'float' object is not callable

How about result = np.average(hwgrades, axis=1)? You will find the documentation here.
