python逐行将列表写入csv

例如列表：list = [‘abc’, ‘def’ , ‘ghi’]

    list = ['abc', def'' , 'ghi']
    with open("./CVE.csv", "a", newline='', encoding='utf-8') as file:
        writer = csv.writer(file ,delimiter=',')
        writer.writerow(list)

结果都在同一行：
abc，def，ghi

若是用writer.writerows()方法，结果每个字母都被逗号隔开：
a,b,c
d,e,f
g,h,i

若是想让列表写入csv中按行切出现被逗号分隔的情况，列表应是：
[[‘abc’], [‘def’], [‘ghi’]]
此时用writer.write()方法结果：
[‘abc’], [“def”], [‘ghi’]
使用writer.writerows()方法才是想要的结果：
abc
def
ghi
