看起来您没有缩进函数的内容。试试这个:
from typing import List
def greatest_difference(nums1: List[int], nums2: List[int]) -> int:
"""Return the greatest absolute difference between numbers at
corresponding positions in nums1 and nums2.
Precondition: len(nums1) == len(nums2) and nums1 != []
>>> greatest_difference([1, 2, 3], [6, 8, 10])
7
>>> greatest_difference([1, -2, 3], [-6, 8, 10])
10
"""
difference = 0
diff_over_term = 0
for i in range(len(nums1)):
diff_over_term = abs(nums1[i] - nums2[i])
if diff_over_term > difference:
difference = diff_over_term
return difference
# and now call your function, notice how these lines aren't indented, that means they are not part of the function definition
list_a = [1, 2, 3]
list_b = [6, 8, 10]
print(greatest_difference(list_a, list_b)
