pandas HDFStore - how to reopen?

Question

I created a file by using:

store = pd.HDFStore(\'/home/.../data.h5\')

and stored some tables using:

store[\'firstSet\'] = df1
s         


        

Answer 1

In my hands, following approach works best:

df = pd.DataFrame(...)

"write"
with pd.HDFStore('test.h5',  mode='w') as store:
    store.append('df', df, data_columns= df.columns, format='table')

"read"
with pd.HDFStore('test.h5',  mode='r') as newstore:
    df_restored = newstore.select('df')
