Save .dta files in python

Question

I\'m wondering if anyone knows a Python package that allows you to save numpy arrays/recarrays in the .dta format of the statistical data analysis software Stat

Answer 1

pandas DataFrame objects now have a "to_stata" method. So you can do for instance

import pandas as pd
df = pd.read_stata('my_data_in.dta')
df.to_stata('my_data_out.dta')

DISCLAIMER: the first step is quite slow (in my test, around 1 minute for reading a 51 MB dta - also see this question), and the second produces a file which can be way larger than the original one (in my test, the size goes from 51 MB to 111MB). This answer may look less elegant, but it is probably more efficient.
