将新行附加到旧的csv文件python
问题描述
我正在尝试向我的旧 csv 文件添加一个新行.基本上,每次我运行 Python 脚本时它都会更新.
I am trying to add a new row to my old csv file. Basically, it gets updated each time I run the Python script.
现在我将旧的 csv 行值存储在一个列表中,然后删除 csv 文件并使用新的列表值再次创建它.
Right now I am storing the old csv rows values in a list and then deleting the csv file and creating it again with the new list value.
想知道有没有更好的方法来做到这一点.
Wanted to know are there any better ways of doing this.
解决方案
with open('document.csv','a') as fd:
fd.write(myCsvRow)
使用 'a'
参数打开文件允许您追加到文件的末尾,而不是简单地覆盖现有内容.试试看.
Opening a file with the 'a'
parameter allows you to append to the end of the file instead of simply overwriting the existing content. Try that.
