我是Python的新手,希望能将伪代码转换为真实代码获得帮助。我目前有一个python脚本,可以完成以下任务:
我的目标是配置一个可选的命令行参数,但是如果给定的话,它将0或1写入名为“ output.csv”的输出文件,而不是数据文件。
当前,创建了output.csv,但不仅具有1或0分类。实际上,它将整个data.csv(读入)文件重写为output.csv(应该写入)
有人可以使用Python吗?希望将我的伪代码转换为真实代码时能得到一些帮助。我目前有一个python脚本,可以完成以下任务:
我的目标是配置一个可选的命令行参数,但是如果给定的话,它将0或1写入名为“ output.csv”的输出文件,而不是数据文件。
如何编辑当前脚本以不重写整个data.csv文件,而仅重写isBad
0或1指示器?

writer.writerow(row + [isBad])
print("Script completed")
答案 0 :(得分:0)
经过足够的调试,我发现需要更改的行。
writer.writerow(row + [isBad])
必须为writer.writerow([isBad])
