extract the column values that bigger than all the values of other column | python pandas












-1















I have a dataframe df that has multiple values:



df = pd.read_csv('file1.tsv', names=['c1'], header=None, skiprows=0, sep='t')

c1
0.94774
0.8367
0.21637
0.8474
0.384784


And another dataframe dn that also have multiple values:



dn = pd.read_csv('file2.tsv', names=['c1'], header=None, skiprows=0, sep='t')

c1
0.33363
0.233
0.45454
0.243
0.28272
0.4874
0.4547
0.1822


I want return a dataframe that has all the values of df that's bigger than all the values of dn



So, the output will be:




c1

0.94774

0.8367

0.8474

          If it is bigger than all, it is bigger than the maximum value:



          df[df['c1'] > dn['c1'].max()]
          # c1
          #0 0.94774
          #1 0.83670
          #3 0.84740
