Question

我是python和pandas的新手，我将.csv文件的长经纬度列表转换为相应的zipcodes并将结果作为一个大数组获取，现在我想将此zipcodes添加到我的.csv文件中新列名为'zipcode'，我该怎么做？提前谢谢！

这是我的csv文件数据

    metrics_time_utc    driver_id   trip_start_time         trip_end_time   trip_start_latitude     trip_start_longitude    trip_end_latitude   trip_end_longitude  trip_distance_travelled     trip_duration   total_fare

这是我要在csv文件中插入的输出

[[     0.      0.]
[ 94105.  94103.]
[ 94133.  94108.]
[ 94133.  94133.]
[ 94114.  94122.]
[ 94104.  94128.]
[ 94128.  94066.]
......

[ 94128.  94066.]
[ 94118.  94116.]
[ 94109.  94102.]]

最好在问题中包含您的代码，否则答案会变成“在黑暗中拍摄”。通常，您的问题可以这样解决：

import pandas as pd
data = pd.read_csv("my.csv")
zipcodes = getzipcodes(data) 
# assuming zipcodes here is 'long array' which length is equal
# to the number of rows in data

data['zipcode'] = zipcodes
data.to_csv("my.csv")

如何将大数组作为列添加到现有csv文件中？
