How to compare two lists in python

Comparison of two lists in python

# Ideas: (Recommended learning: Python video tutorial)

First determine whether the lists are of equal length;

If they are equal, determine whether the values ​​at the corresponding index positions are the same;

If they are different, Record the error value and index value of the two

The code is as follows:

def compare(list1, list2):
    error = []
    error_index = []
    if len(list1) == len(list2):
        for i in range(0, len(list1)):
        #两个列表对应元素相同，则直接过
            if list1[i] == list2[i]:
                pass
            else:#两个列表对应元素不同，则输出对应的索引
                error.append(abs(list1[i]-list2[i]))
                # print(i)
                error_index.append(i)
    print(error)
    print(error_index)
