什么是ValueError？

Question

我有一个简单的python脚本，需要用户输入：

limit=int(input())
answer=1
a=[]
for i in range(limit):
    data=int(input())
    a.append(data)
for j in a:
    answer = answer*j+10**9+7
print(answer)

当我运行它时，我不断收到像这样的错误。

Execution failed.
ValueError: could not convert string to float : '1 2 3 4 5'

Stack Trace:
Traceback (most recent call last):
File "/hackerearth/PYTHON3_12/s_0b.py3", line 5, in 
data=int(float(input()))
ValueError: could not convert string to float: '1 2 3 4 5'

什么是ValueError？如何解决此问题？

Answer 1

您需要一次解析每个数字。您试图一次输入所有数字，这将不起作用。试试这个：

{

    {
        "SensorType": "Power",
        "Value": 15.2162886
    },
    {
        "SensorType": "Temperature",
        "Value": 69
    }
],

    {
        "SensorType": "Temperature",
        "Value": 41
    }
],
"CPU Core #2": [
    {
        "SensorType": "Temperature",

        "Value": 60.15625
    },
    {

    }

    {
        "SensorType": "Temperature",

    },
    {
        "SensorType": "Clock",
        "Value": 3100.001
    },
    {
        "SensorType": "Load",

    }

    {
        "SensorType": "Power",

}

我将您的代码更改为1）在循环前输入 ，然后2）将其分成一个列表，其中每个元素都是原始字符串中的数字之一，其中3）然后可以将其解析为循环中的数据。
