python - 尝试在正确的标题下按顺序将测试结果附加到文本文件中

问题描述

试图让这些测试系列将其结果添加到内容中，然后在脚本结束时将收集到的内容写入文本文件，并在标准规定的正确标题下。第一个测试正常工作，但之后没有一个。没有错误，只是没有附加信息。我需要弄清楚我做错了什么以及如何将内容附加在正确的部分下。请帮忙！

解决方案

这是因为每次您使用 python 向 .txt 文件写入内容时，整个文件都会被擦除，然后它会写入您输入的内容，所以当您第一次运行它时，文件会被写入第二次、第三次、第四次……时间文件的内容被取消并重写，因此您看不到任何更改，因此您应该尝试以下操作：

with open(reportFile, "r") as file:
    old = file.read()
#then 
with open(reportFile, 'a') as f:
    f.write(old + "\n" + content)

我敢肯定有更好的方法可以做到这一点，但这项工作也
