python如何使用csv文件中的数据运行函数

Question

我有一个在 pinterest 上执行任务的代码，它是手动工作的，必须在“pin_id =”区域填写一个数字，当我运行时，将完成重新固定，但是，我想：

1. 从单列 csv 文件中填写“pin_id”区域中的数据。
2. 每个任务之间有一些延迟（5-10 秒）。
3. 能够限制每次运行的行数， 例如50，CSV文件可能有数百个数据，我不想一次运行所有数据。

[edited] 代码已编辑，我试过的最新的， 代码如下：

 import json
 import random
 import time
 import os
 from csv import reader
 import csv
 import pandas as pd
 from py3pin.Pinterest import Pinterest

 pinterest = Pinterest(email='xxxx',
                  password='xxxx',
                  username='xxxx',
                  cred_root='cred_root')
  def repin(pin_id='', board_id=myboard Id, section_id=None):
  return pinterest.repin(board_id=board_id, pin_id=pin_id, 
  section_id=section_id)

  with open('pin-test.csv','r') as csvfile:  # use with to auto-close file
  for row in csvfile.readlines():  # pin_id
   repin(row)  # board_id and section can use defaults
   time.sleep(random.randint(1,3)) # wait 1-3 seconds

目前还没有限制要运行的行数的功能，

无论如何，编辑后的脚本也不起作用，

我在运行时得到这些：

C:\Users\Dav111\Desktop\Python\py3-pinterest-master>z-repin-test.py
Traceback (most recent call last):

section_id=section_id)

感谢您对此的帮助。

这看起来很简单。只需在迭代数据文件时调用该函数即可。

import random, time

def repin(pin_id='Id number from csv file', board_id=12345, section_id=None):
   return pinterest.repin(board_id=board_id, pin_id=pin_id, section_id=section_id)
   

with open('pin-test.csv','r') as csvfile:  # use with to auto-close file
   for row in csvfile.readlines():  # pin_id
       repin(row)  # board_id and section can use defaults
       time.sleep(random.randint(1,3)) # wait 1-3 seconds
