本地debug 调试leetcode 代码（用于研究不懂的题解代码和调试自己的代码）

1.导入包 是对变量解释的包

from typing import *

2.将代码拷过来

#举例 二分查找

class Solution:
    def search(self, nums: List[int], target: int) -> int:
        low, high = 0, len(nums) -1
        while low<= high:
            mid = (low+high) //2
            guess = nums[mid]
            if guess == target:
                return mid
            elif guess > target:
                high = mid - 1
            else:
                low = mid + 1
        else:
            return -1

3.新建实例类

test = Solution()

4.调用类的方法，并输入测试用例

测试用例从下面的红色方框里获得

test.search([-1,0,3,5,9,12],9)

完整代码

# 导入包 是对变量解释的包 
from typing import *
# 代码
class Solution:
    def search(self, nums: List[int], target: int) -> int:
        low, high = 0, len(nums) -1
        while low<= high:
            mid = (low+high) //2
            guess = nums[mid]
            if guess == target:
                return mid
            elif guess > target:
                high = mid - 1
            else:
                low = mid + 1
        else:
            return -1
# 新建实例
test = Solution()
# 输入测试用例，调用方法
test.search([-1,0,3,5,9,12],9)

然后在编辑器里设置断点调试就可以了
（左侧有相关调试变量的数值）
