How to select cells greater than a value in a multi-index Pandas dataframe?
If what you are trying to do is to select only rows where any one column meets the condition , you can use DataFrame.any() along with axis=1 (to do row-wise grouping) . Example -
In [3]: dfOut[3]: A B C0 1 2 31 3 4 52 3 1 4In [6]: df[(df <= 2).any(axis=1)]Out[6]: A B C0 1 2 32 3 1 4Alternatively, if you are trying for filtering rows where all columns meet the condition , use .all() inplace of .any() . Example of all -
In [8]: df = pd.DataFrame([[1,2,3],[3,4,5],[3,1,4],[1,2,1]],columns=['A','B','C'])In [9]: dfOut[9]: A B C0 1 2 31 3 4 52 3 1 43 1 2 1In [11]: df[(df <= 2).all(axis=1)]Out[11]: A B C3 1 2 1
