使用Python在CSV的特定行上开始读取和写入 [英] Start reading and writing on specific line on CSV with Python

问题描述

我有一个CSV文件，如下所示：

I have a CSV file that looks like this:

COL_A,COL_B
12345,A=1$B=2$C=3$

如何读取该文件并将其写回新文件，但只是第二行（行）？
我想输出文件包含：

How do I read that file and wrote it back to a new file but just the second row (line)? I want the output file to contain:

12345,A=1$B=2$C=3$

$ b

谢谢！

Thanks!

推荐答案

以下代码读取csv，提取第二行，然后将第二行写入另一个文件。

The following reads your csv, extracts the second row, then writes that second row to another file.

with open('file.csv') as file:
    second_line = list(file)[1]

with open('out.csv', mode = 'w') as file:
    file.write(second_line)
