My function needs two params(a,b) and if...break, which seems redundant. Can it be made prettier?

def slice_list(lst,num):
 """
 Given a list or Numpy array,
 get consecutive tuples based on specific window. 
 """
 rst = []
 for i,_ in enumerate(lst):
 a = i
 b = i + num
 if len(lst[a:b])<num:
 break
 rst.append(tuple(lst[a:b]))
 return rst

Example:

>>> lst = np.array([10, 11, 12, 13, 26, 28])
>>> slice_list(lst,4)
[(10, 11, 12, 13), (11, 12, 13, 26), (12, 13, 26, 28)]
