Convert .CSV files to .DTA files in Python

Question

I\'m looking to automate the process of converting many .CSV files into .DTA files via Python. .DTA files is the filetype that is handled by the Stata Statistics language.

Answer 1

You need rpy2 for Python and also the foreign package installed in R. You do that by starting R and typing install.packages("foreign"). You can then quit R and go back to Python.

Then this:

import rpy2.robjects as robjects
robjects.r("require(foreign)")
robjects.r('x=read.csv("test.csv")')
robjects.r('write.dta(x,"test.dta")')

You can construct the string passed to robjects.r from Python variables if you want, something like:

robjects.r('x=read.csv("%s")' % fileName)
