How to convert csv/txt file to hdf5?

[asanakoy]

For csv

import pandas as pd
df = pd.read_csv(filepath)
df.to_hdf(fout_filepath)

I just want to add to @asanakoy's answer that deepdish is fully compatible with pandas too, essentially calling to_hdf internally. These two will create the same HDF5 file (both can be loaded with deepdish):

df.to_hdf(filename, key='table')
dd.io.save(filename, dict(table=df)

However, deepdish extends this by allowing you to save multiple data frames inside a single HDF5 file, intermixed with the other data types supported by deepdish:

dd.io.save(filename, dict(table=df, more_tables=[df1, df2, df3]))
