Question

我遇到了这段代码的问题

import csv
temp = open("townsfile.csv", "r")
towns = temp.read()
temp.close()
print(towns)

eachTown = towns.split("\n")
print (eachTown)

record = eachTown.split(",")

for line in eachTown:
    record = eachItem.split(",")

print(record)

newlist=[]

newlist.append(record)

newlist=[]
for eachItem in eachTown:
record = eachItem.split(",")
newlist.append(record)

print(newlist)

它返回此错误

Traceback (most recent call last):
  File "N:/Python practice/towns.py", line 10, in <module>
    record = eachTown.split(",")
AttributeError: 'list' object has no attribute 'split'

任何人都可以帮助我吗

Answer 1

eachTown = towns.split("\n")

此代码返回列表。列表没有属性拆分。你应该替换

record = eachTown.split(",")

像这样

records = [rec.split(",") for rec in eachTown]

但如果您开始使用module csv来阅读此文件，那就更好了。

Answer 2

csv模块为您提供了此文本解析功能，您无需自己动手。

import csv
with open("townsfile.csv", "r") as f:
    reader = csv.reader(f, delimiter=',')
    towns = list(reader)

print(towns)

您遇到的问题是list.split()不存在，您尝试使用str.split()，但您已将其拆分为list个str。您需要为列表中的每个str执行此操作。

AttributeError：'list'对象在Python中没有属性'split'
