Dear all, 
I am analyzing my single cell data using Scanpy package and as you may knwo it stores my data in anndata object which is a panda like data frame. I am interested to know which of my cells express the gene x.  Does anyone has an idea how would I be able to access that information? I am not really familiar with data structures in Python and specially panda
 
Ok I found my answer :D It was not that complicated

    adata[:, adata.var_names.str.match('genenames')]
