Reference dictionary values [duplicate]

Question

I have a dataframe, df with columns headers A, B , C, D

can I reference these headers from this dictionary?

dic={'key1':['A','B'],
key2: [C,D]}

df[key1[0]]

giving the output of just column A?

Yes you can but you need

df[dic['key1']]
     A    B
0  NaN  NaN

df[[dic['key1'][0]]]
     A
0  NaN
