I have this:

dfs_in_list = [df1, df2, df3, df4, df5]

I want to concatenate all combinations of them one after the other (in a loop), like:

pd.concat([df1, df2], axis=1) 
pd.concat([df1, df3], axis=1)   
pd.concat([df1, df2, df3], axis=1)  
... 
pd.concat([df2, df3, df4, df5], axis=1) 

Any ideas?

import itertools
import pandas as pddfs_in_list = [df1, df2, df3, df4, df5]combinations = []
for length in range(2, len(dfs_in_list)):combinations.extend(list(itertools.combinations(dfs_in_list, length)))for c in combinations:pd.concat(c, axis=1)
