如何读取CSV的每一行并通过用户函数调用该值，然后将结果保存在一个csv文件中？

Question

import csv
import time
with open("AuthorName.csv", "rb") as f:
    reader = csv.reader(f, delimiter="\t")
    for line in enumerate(reader):
        time.sleep(2)
        print line[1]

The result is like:

['rhaf_hq']
['Digixp']
['bujhoapp']
['styhuang']
['mkasanm']

How can I invoke these lists in the function below: Screen_names

print json.dumps(get_user_profile(twitter_api, screen_names=["SocialWebMining"]), indent = 1 )

Here's a sample function that seems to do what you asked. It works as follows:

1. Open your current file (fileName)
2. Store said file's content into a list (values[])
3. Create the file you want to write in (newValues.csv)
4. Create an object to write with (valueWriter)
5. write each value from your list into the new file (the writerow() function)

.

import csv

def make(fileName):
    with open(fileName) as file:
        values = []
        #Putting all your file's data in a list
        for each in file:
            each = each.strip()
            values.append(each)
    #Creating your new file
    with open('newValues.csv','w') as newFile:
        #creating a variable to write with
        valueWriter = csv.writer(newFile)
        #writing each individual value to your new file
        for each in values:
            valueWriter.writerow([each])
