如何在现有的csv文件中添加大数组作为列？

我是python和pandas的新手，我把经度和纬度的长列表从.csv文件转换为相应的zipcode，并以大数组的形式获得结果，现在我想将这个zipcode添加到我的.csv文件中作为新的列名为“邮编”，我该怎么做？先谢谢你！如何在现有的csv文件中添加大数组作为列？

这是更好地包括在这个问题你代码中插入，否则答案成为'在黑暗中射击'。一般来说，你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")
