用python读取csv文件格式

Question

我正在尝试从csv格式的文件中读取天气数据。我打印了文件的索引和头，我看到日期的索引为零。我尝试在python中使用datetime模块来访问日期，它告诉我有一个索引错误。以下是我收到的错误消息：

Traceback (most recent call last):
  File "accra_weather.py", line 15, in <module>
    current_date = datetime.strptime(row[0], "%Y-%m-%d")
IndexError: list index out of range

以下是完整代码：

import csv
from datetime import datetime

filename = "accra_month.csv"
with open(filename) as f:
    reader = csv.reader(f)
    header_row = next(reader)

    dates, highs = [], []
    for row in reader:
        try:
           current_date = datetime.strptime(row[0], "%Y-%m-%d")
           high = int(row[1])
        except ValueError:
            print(date, "Missing data")
        else:
            highs.append(high)
            dates.append(current_date)

这也是我要检查的天气数据：
