Python Pandas DataFrame时间转换为时间戳代码示例 - 详细教程

import\u0020pandas\u0020as\u0020pd\n\n#\u0020创建一个DataFrame\ndf\u0020=\u0020pd.DataFrame({'date':\u0020['2021-01-01',\u0020'2021-01-02',\u0020'2021-01-03'],\n 'time':\u0020['08:00:00',\u0020'12:30:00',\u0020'18:45:00']})\n\n#\u0020将date和time合并为一个datetime列\ndf['datetime']\u0020=\u0020pd.to_datetime(df['date']\u0020+\u0020' '\u0020+\u0020df['time'])\n\n#\u0020将datetime转换为时间戳（以秒为单位）\ndf['timestamp']\u0020=\u0020df['datetime'].astype(int)\u0020//\u002010**9\n\nprint(df)
