pandas 转化 数据为DataFrame后,DataFrame不能够print
否则会报错AttributeError: 'NoneType' object has no attribute 'total_seconds'

#data的数据结构大致为[{...,'datetime':datetime.datetime(2022, 7, 4, 13, 55, 0, 500000, tzinfo=zoneinfo.ZoneInfo(key='Asia/Shanghai')),...},{}]
#其中包含的datetime是出现错误的原因

df = pd.DataFrame(data)
df['datetime']

AttributeError: 'NoneType' object has no attribute 'total_seconds'

解决办法:指定时区
df['datetime'] = df['datetime'].dt.tz_convert('Asia/Shanghai')
