我想你可以简单
>将时间戳定义为每个DataFrame的索引(使用set_index)
>使用连接将它们与“外部”方法合并
> Optionnaly将时间戳转换为日期时间
这是它的样子.
# generating some test data
timestamp = [1440540000, 1450540000]
df1 = pd.DataFrame(
{ imestamp: timestamp, a: [val_a, val2_a], : [val_b, val2_b], c: [val_c, val2_c]})
# building a different index
timestamp = timestamp * np.random.randn(abs(1))
df2 = pd.DataFrame(
{ imestamp: timestamp, d: [val_d, val2_d], e: [val_e, val2_e], f: [val_f, val2_f],
g: [val_g, val2_g]}, index=index)
# keeping a value in common with the first index
timestamp = [1440540000, 1450560000]
