运用循环求和( sum operation in python) 1.for loop example 1: sum of 1+2+...+10 *** >>> sum=0 >>> for x in [1,2,3,4,5,6,7,8,9,10]: sum=sum+x >>> print(sum) *** example 2: sum of 1+2+...+100 *** sum=0 for x in range (101): sum=sum+x print(sum) ...
接受任何 Python iterable 作为它的第一个参数使得sum()泛型、可重用和多态。由于此功能,您可以使用sum()列表、元组、集合、range对象和字典: >>> >>># Use a list>>> sum([1,2,3,4,5])15>>># Use a tuple>>> sum((1,2,3,4,5))15>>> # Use aset>>> sum({1,2,3,4,5})15>>># ...

In Python, you can get the sum of all integers in a list by using the sum method: sum = sum([1, 2, 3, 4, 5]) print(sum) # 15 However, this does not work on a list of integer strings: #
for i in range(len(nums)): if nums[i] in hash_dict: return [hash_dict[nums[i]],i] else: hash_dict[target - nums[i]] = i 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 测试结果 Runtime:36 ms beats 100% of python3 submissions...
