如何将数据存储在CSV文件中？

Question

I have some data I want to store in a csv file:

result  |  DataFrame  |  (90422, 17)  |  Column names: age, job, marital

However, my script only creates an empty csv file. How can I get it to actually output the data that I want?

for row in result:
    counter[row[0]] += 1
writer = csv.writer(open('file.csv', 'w'))
for row in result:
    if counter[row[0]] >= 0:
        writer.writerows(row)

Answer 1

使用pandas库中集成的to_csv方法

my_dataframe.to_csv('name_of_file', sep=',')
