leetcode | Median of Two Sorted Arrays (Python)

本题思路比较简单。
学习了extend()和append()的不同之处。

num1 = [5,2]
num2 = [3,4]
num1.extend(num2)      #extend()
print (num1)

num1 = [5,2]
num1.append(num2) 	   #append()
print (num1)

[5, 2, 3, 4]
[5, 2, [3, 4]]

class Solution:
    def findMedianSortedArrays(self, nums1: list, nums2: list) -> float:
        nums1.extend(nums2)
        nums1.sort()
        if len(nums1)%2 == 0:
            median = (nums1[int((len(nums1)-1)/2)] + nums1[int((len(nums1)-1)/2) +1]) / 2
#如果长度为偶数     
        else:
            median = nums1[int(len(nums1)/2)]
#如果长度为奇数
        return median

num1 = [5,2]
num2 = [3,4]
print (Solution().findMedianSortedArrays(num1,num2))
