比特币的泡沫大还是房价的泡沫大?

什么平台?出入金方便吗

@shyrock 确实有 2.7 和 3.8 版本 怎么把 2.7 删了?或者默认执行 3.8 版本?

@inhd 我现在是 big sur 系统 我现在安装的应用在恢复系统之后还在吗?桌面上的文件在不抹掉磁盘的情况下不会丢失?

@xiaolinjia list 的类型是 pymongo.cursor.Cursor db[index + 1]['a'] 就提示错误了

@xiaolinjia 谢谢!

具体怎么写啊~以上的方法都试了好像不行啊

@OutOfMemery 我同事用的 win10 看着还不错

@OutOfMemery 可是我用的 mac

加一个 Windows10 聚焦推荐壁纸呗

@capallen 忽略吧~ 我弄错了 不好意思

@capallen 你好 再问个问题
按照你的代码
df 数据的顺序对了

close = df['close']
date = df['trade_date']

之后再 print 怎么又回到降序了呢?

df 重新排序后:
ts_code trade_date open high low close pre_close change pct_chg vol amount
