在处理CSV文件时出现空行问题可能有多个原因，但我们可以通过一些简单的步骤来解决。确保使用csv.writer对象的writerow方法时，不要传递包含空值的列表，这可能导致生成空行。同样，使用writerows方法时，确保传递的嵌套列表不包含空子列表。此外，打开文件时使用newline=''参数，尤其是在Windows系统上，以防止额外的换行符...

writer(file) 11 writer.writerows(data2)上述代码将创建一个名为"data2.csv"的CSV文件,并使用csv.writer函数创建一个写入器对象。然后,使用writerows()方法将数据写入CSV文件。注意,在打开文件时,我们将newline=''传递给open()函数,这是为了避免在Windows系统上出现额外的空行。
