MS Learn Python - 代码未在 Visual Studio 中运行（新手）

Question

我是编程新手，已经开始了 Microsoft 的 Python 第一步课程。我已经完成了 Python (3.9)、Visual Studio Code、Visual Studio 的 Python 扩展的安装，并开始了一些练习。

我曾尝试运行一些练习程序，但没有取得多大成功。为了尝试找出问题的根源，我从其中一个示例中复制了提供的 Microsoft 代码。据我所知，这些问题似乎是我极其有限的：

1. 程序未运行/部分运行；和
2. 程序返回以下错误：ValueError: invalid literal for int() with base 10:

我的假设是这可能与 Visual Studio 设置有关，因为 Microsoft 示例代码的输出与提供的输出不匹配。

源码是

print("Today's date?")
date = input()
print("Breakfast calories?")
breakfast = int(input())
print("Lunch calories?")
lunch = int(input())
print("Dinner calories?")
dinner = int(input())
print("Snack calories?")
snack = int(input())
total = breakfast + lunch + dinner + snack
print("Calorie content for " + date + ": " + str(total))

我运行程序3次后得到的终端输出是：

PS C:\Users\domch\OneDrive\5_CPD\Python learn\Hello> & C:/Users/domch/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/domch/OneDrive/5_CPD/Python learn/Calorie counter/calories.py"
Today's date?
& C:/Users/domch/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/domch/OneDrive/5_CPD/Python learn/Calorie counter/calories.py"
Breakfast calories?
& C:/Users/domch/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/domch/OneDrive/5_CPD/Python learn/Calorie counter/calories.py"
Traceback (most recent call last):
  File "c:\Users\domch\OneDrive\5_CPD\Python learn\Calorie counter\calories.py", line 4, in <module>
    breakfast = int(input())
ValueError: invalid literal for int() with base 10: '& C:/Users/domch/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/domch/OneDrive/5_CPD/Python learn/Calorie counter/calories.py"'
PS C:\Users\domch\OneDrive\5_CPD\Python learn\Hello> 

我了解此示例代码的“解决方案”在终端中应该如下所示：

Today's date?
December 7th, 2020
Breakfast calories?
250
Lunch calories?
300
Dinner calories?
500
Snack calories?
150
Calorie content for December 7th, 2020: 1200

任何帮助将不胜感激！

Answer 1

您没有运行该程序 3 次，但实际上在前一次运行仍期待您的输入时尝试运行它（查看作为输入读取的版本（它在来自 ValueError 异常的错误消息中：

'& C:/Users/domch/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/domch/OneDrive/5_CPD/Python 学习/卡路里 计数器/calories.py"'

。在 VS Code 中查找终端选项卡，并在第一次运行时在此处输入输入。
