How to pass multiple lists to a function?

def lagr(k, mx, my):
  i=0
  j=0
  Lagrange=0
  while i<n:
    numerator=1
    denominator=1
    while j<n:
      if(i!=j):
        numerator=numerator*(k-mx[j])
        denumerator=denumerator*(mx[i]-mx[j])
        j+=1
    Lagrange=Lagrange+my[i]*numerator/denumerator
    i+=1
  return Lagrange
........
while i<m:
  L.insert(i,lagr(array[i],array,f))
  i+=1

i'm just learning :
array and f are lists

Answer 1

def lagr(*arrays):
-
lagr(array_1, array_2, massive_3)
