动态 append 数据到 pandas dataframe

Question

I'm trying to build my code as general as possible.

Part of my code is to build couple of data frames (which latter would be joined to one 'master' data frame), however each of this partial data frames contains variable number of columns.

I'm passing to my function a list which contains the name of the columns names. How can I make this as general as possible. If I'll pass to my function any of list1 or list2

list1 = ['a.element1', 'a.element2']
list2 = ['b.elementA', 'b.elementB']

Eventual df1 shall contain columns element1 and element2 and df contain columns elementA and elementB

df1 = myFunciton(list1, data1)
df2 = myFunciton(list2, data2)

Answer 1

Do you mean this?

df_master= df1.append([df2, df3, .., dfn])

Otherwise, please give a minimal reproducible example of what you mean and want to achieve.
