python - 为什么我的 python 脚本在 IDLE 和从 CMD 执行而不是双击时工作

Question

我正在努力调试它，但恐怕它超出了我目前的理解。

我在 python 中创建了一个简单的脚本，其目的是将字符串作为输入（从谷歌表格复制粘贴）并将其转换为适合上传到谷歌日历的 csv 文件。它是硬编码的，以适应我们工作中轮班计划的格式。可以说示例性输入可以是：MSLS-1Comp-offES-1..ES-22。然后程序根据指定的规则解析输入，将解析的项目打印为列表，最后以正确的格式创建一个 csv 文件。

这是问题所在：该程序在我尝试的任何地方都可以完美运行，除非我尝试通过在桌面上双击它来运行它（Windows10）。从 CMD、IDLE 或在线运行时，程序可以正常工作并产生预期的结果而不会出现任何错误。我写的其他简单脚本，从桌面运行没问题。在这个特定的程序中，程序打开（与所有其他程序一样，在 python3.9 中），但在特定的行中退出（同样，当我从 cmd、IDLE 或在线运行该程序时，它不会发生）。通过插入打印功能，我设法找到了程序“崩溃”的地方。在我看来，由于某种原因，程序退出/崩溃就行了with io.open("shifts.csv", "w", encoding="utf-8-sig") as f:。

与代码有关吗？那为什么只使用命令提示符在同一系统上运行时运行正常？这与我在计算机上设置 python 的方式有关吗？在这种情况下，为什么我编写的其他脚本可以从桌面完美运行？我在这里真的很困惑。我将非常感谢任何建议。谢谢！

这是完整的代码：

import subprocess
import sys
import io

year = "2021"
month = input("Please enter month in number format (e.g., '07' for June):\n")

shifts = input("Please paste your shifts:\n")

word = ''
shifts_list = []
for char in shifts: # iterate through the string
    word = word + char # add the character to the word
    if(char in ['1','2','3','.']): # check if the character at current iteration is one of the characters in the list
        shifts_list.append(word) # add the word formed by now to the list
        word = '' # re-initialize the word variable to an empty string so as to start the next word
    if (char in ['S'] and word[-2] in ['M']):
        shifts_list.append(word) # add the word formed by now to the list
        word = '' # re-initialize the word variable to an empty string so as to start the next word

print(shifts_list)

    f.write(headers)

    for day, shift in enumerate(shifts_list):

            f.write(subjects[3] + ', ' + date +', ' + start_times[3] + ', ' + date + ', ' + end_times[3] + ', ' + description + ', ' + "TRUE\n")
