Question

<ul>
            <item v-for='cat in categories' :category='cat'></item>

        </ul>

错误：import pandas as pd import datetime def open_csv(path): try: df = pd.read_csv(path) return df except FileNotFoundError: print("ERR: FileNotFoundError", path) data = open_csv("historical/BNBBTC") for d in data["Open_time"]: print(d) print(type(d)) print(datetime.datetime.fromtimestamp(d).strftime('%Y-%m-%d %H:%M:%S'))

我不明白是什么问题？如果b = int（“ 1514764800000”），那么一切正常！

Answer 1

import time并将datetime.datetime.fromtimestamp(d).strftime('%Y-%m-%d %H:%M:%S')替换为time.strftime('%Y-%m-%d %H:%M:%S')

Answer 2

有点晚了，但您遇到的问题是时间戳以毫秒为单位，请像这样转换：

        milliSeconds = timestamp % 1000
        timestamp = timestamp / 1000
        converted = datetime.fromtimestamp(timestamp).strftime('%Y-%m-%d %H:%M:%S') + f".{milliSeconds}"

datetime OSError：[Errno 22]无效的参数
