python - 列表未完全卸载到记事本中？

Question

我有两个名为 itemIds 和 itemRap 的列表，其中都包含 1,890 个项目。我的目标是将这些列表卸载到单独的记事本中。这是代码段：

#unloading itemIds and itemRap lists into files
x = 0
for x in range(len(itemIds)):
    itemId = (str(itemIds[x])+"\n" )
    itemPrice = (str(itemRap[x])+"\n" )
    itemIdFile.write(itemId)
    itemRapFile.write(itemPrice)
    x = x + 1

每当我运行此段时，并非列表中的所有项目都最终出现在记事本中——它们都缺少 300-400 个项目。python 不能这么快地将项目添加到记事本吗？到底是怎么回事？有没有潜在的解决方案？

如果您想自己尝试一下，这是我的完整代码：

import json, urllib
import os
itemRap = []
itemIds = []
pageNumber = 1
#initiating to make first while loop run
url = "https://search.roblox.com/catalog/json?Category=2&PageNumber=" + str(pageNumber)
response = urllib.urlopen(url)
data=json.loads(response.read())

while data:
#gets data for 1 page of collectibles
    #puts data into lists based on Id and RAP
    counter = 0
    while counter != len(data):
        if data[counter]['BestPrice'] != '':
            itemIds.append(data[counter]['AssetId'])
            itemRap.append(data[counter]['BestPrice'])
        counter = counter + 1

    pageNumber = pageNumber + 1
    url = "https://search.roblox.com/catalog/json?Category=2&PageNumber=" + str(pageNumber)
    response = urllib.urlopen(url)
    data=json.loads(response.read())

print(len(itemIds))
print(len(itemRap))

#clears important files- change to graph data later?
itemIdFile = open("ItemIds.txt","a+")
itemRapFile = open("ItemRap.txt","a+")
itemIdFile.truncate(0)
itemRapFile.truncate(0)

#unloading itemIds and itemRap lists into files
x = 0
for x in range(len(itemIds)):
    itemId = (str(itemIds[x])+"\n" )
    itemPrice = (str(itemRap[x])+"\n" )
    itemIdFile.write(itemId)
    itemRapFile.write(itemPrice)
    x = x + 1
