Write a Python program to join two given list of lists of same length, element wise

def elementswise_join(l1, l2):
    result = [x + y for x, y in zip(l1, l2)]
    return result

nums1 = [[10,20], [30,40], [50,60], [30,20,80]]
nums2 = [[61], [12,14,15], [12,13,19,20], [12]]
print("Original lists:")
print(nums1)
print(nums2)
print("\nJoin the said two lists element wise:")
print(elementswise_join(nums1, nums2))

list1 = [['a','b'], ['b','c','d'], ['e', 'f']]
list2 = [['p','q'], ['p','s','t'], ['u','v','w']]
print("\nOriginal lists:")
print(list1)
print(list2)
print("\nJoin the said two lists element wise:")
print(elementswise_join(list1, list2))
