1、打开JUPYTER NOTEBOOK，新建一个空白的PY文档。
3、nums = [1,3,5,6]target = 2for i in range(len(nums)): if nums[i] == target: print(i)如果数字不在，就不返回结果。
5、nums = [1,3,5,6]target = 2if target in nums: print(nums.index(target))else: for i in range(len(nums)): if nums[i] < target and nums[i+1] > target: print(i+1)如果不在就插入相应的位置。这里是假设的位置，返回位置的序列。
10、nums = [1,3,5,6觥终柯计]target = 7for i in range(len(nums)): if nums[0] > target: print(0) break elif nums[i] == target: print(i) break elif nums[i] < target and nums[i+1] > target: print(i+1) break elif target > nums[-1]: print(len(nums)) breaknums = [1]target = 2for i in range(len(nums)): if nums[0] > target: print(0) break elif nums[i] == target: print(i) break elif target > nums[-1]: print(len(nums)) break elif nums[i] < target and nums[i+1] > target: print(i+1) break多测试一下两个实例。
11、nums = [1,3,5,6]target = 7for i in range(len(nums)): if nums[0] > target: print(0) break elif nums[i] == target: print(i) break elif target > nums[-1]: print(len(nums)) break elif nums[i] < target and nums[i+1] > target: print(i+1) break最后调整一下这样就是比较容易理解的。
