我有一个带的字符串列表
tickers = [AA, GME...]
It is just an example I have a variable with 50 tickers
50_tickers = [AA,GME,FB,MSFT...] 50 of them
And I need to combine all of them following the same pattern as below
AA数据集看起来像这个
2021:03:21 | 33.45
2021:03:22 | 33.50
2021:03:23 | 33.60
2021:03:24 | 33.70
GME数据集看起来像这个
2021:03:21 | 10.45
2021:03:22 | 11.50
2021:03:23 | 12.60
2021:03:24 | 12.65
我想把这两个数据集组合起来,看起来像这个
time | price AA | price GME
2021:03:21 | 33.45 | 10.45
2021:03:22 | 33.50 | 11.50
2021:03:23 | 33.60 | 12.60
2021:03:24 | 33.70 | 12.65
以下是我尝试过的
for combine in tickers:
df = pd.DataFrame(combine)
df.concat(df[combine])
我知道它不起作用。我不知道其他方法可以将两个数据集合并为一个具有公共时间列的数据集。我很感激你的提示谢谢
你可以这样做
df=None
flag=False
for combine in tickers:
if not Flag:
df = pd.DataFrame(combine)
flag=True
else:
df_t = pd.DataFrame(combine)
df = df.merge(df_t, on='time')
df
