Adding Numbers in a Range with for() Loop
提问by kylie.a
I'm having trouble filling out a question on an online python tutorial. It seems really simple but for the life of me I can't figure it out. This is the problem "write a for loop that adds all the numbers 1 to 10 and returns the sum." And this is the code I have been trying:
我在在线 Python 教程中填写问题时遇到问题。这看起来很简单，但对于我的生活，我无法弄清楚。这就是问题“编写一个 for 循环，将所有数字 1 到 10 相加并返回总和。”这是我一直在尝试的代码：
def run():
sum = 0
for i in range(11):
sum += i
return sum
What am I doing wrong? Thanks for any help.
我究竟做错了什么？谢谢你的帮助。

You're returning within the loop, after one iteration. You need to dedent the returnstatement so that it falls outside the loop:
经过一次迭代，您将在循环内返回。您需要删除该return语句，使其落在循环之外：
def run():
sum_ = 0
for i in range(11):
sum_ += i
return sum_

You are returning the sum from within the for loop. Indent it outside. Keep it at the same level of indentation as for.
您正在从 for 循环中返回总和。在外面缩进。保持与 for 相同的缩进级别。

您需要删除 return 语句，使其落在循环之外：
def addNumbers(num)
sum=0
for i in range(0,num+1)
sum=sum+i
return sum

if anyone want to know how to add 0 + 1 count until 100. There is it!
如果有人想知道如何将 0 + 1 计数加到 100。就是这样！
x = 0
while x<100:
x += 1
print(x)
