Suppose I have a dictionary of pandas
dataframes where the keys are 0, 1, 2, ..., 999
, and the values are dataframes like this ( test_df
):
A B C
0 1.438161 -0.210454 -1.983704
1 -0.283780 -0.371773 0.017580
2 0.552564 -0.610548 0.257276
3 1.931332 0.649179 -1.349062
4 1.656010 -1.373263 1.333079
5 0.944862 -0.657849 1.526811
Say that the index means nothing to you, and that you want to create a new dataframe where columns A
and B
are concatenated:
mydf=pd.concat([test_df[0]['A'],test_df[0]['B']], axis=1, keys=['A','B'])
Now, can I use this line inside a for loop which iterates over all the keys in my dictionary of dataframes?
If not, what would be another way of doing this? The result would be a dataframe with two columns, A
and B
, and 6x1000
rows. The index column would therefore go from 0
to 5999
.
