尝试将 csv 转换为字典列表时出现索引错误

Question

我是编码新手，所以这可能是一个愚蠢的问题。我不明白列表索引如何超出范围。变量“I”范围应该是文件中的行数，并且“标题”只要“标题”中有标题即可。但我收到一条错误消息：“data[title].append(row[i]) IndexError：列表索引超出范围”

谢谢你。

csv 文件如下所示：

DATE,OPEN,HIGH,LOW,CLOSE,SPREAD
2024-03-25 00:00,1.08071,1.08073,1.08068,1.08072,95

2024-03-25 00:10,1.08088,1.08088,1.08079,1.08079,28

这是我的代码：

import csv
import datetime

import matplotlib.pyplot as plt


filename = "pathtocsv.csv"

with open(filename, "r") as file:
    csv_reader = csv.reader(file)
    headers = next(csv_reader)
   
    data = {}
    for title in headers:
        data[title] = []

    for row in csv_reader:
        for i, title in enumerate(headers):
            data[title].append(row[i])
    
for i in range(len(data["DATE"])):
    data["DATE"][i] = datetime.datetime.strptime(data["DATE"][i],'%Y-%m-%d %H:%M')
        
for i in range(len(["OPEN"])):
    data["OPEN"][i] = float(["OPEN"][i])

for i in range(len(["CLOSE"])):
    data["CLOSE"][i] = float(["CLOSE"][i])
   

fig, ax = plt.subplots()
ax.plot(["DATE"], ["OPEN"])
ax.plot(["DATE"], ["CLOSE"])
fig.autofmt_xdate()
fig.show()

If csvfile is a file object, it should be opened with newline=''

在代码中将是-

with open(filename, newline='') as file:
