pandas.read_stata

pandas.read_stata(filepath_or_buffer, convert_dates=True, convert_categoricals=True, encoding=None, index_col=None, convert_missing=False, preserve_dtypes=True, columns=None, order_categoricals=True, chunksize=None, iterator=False) [source]

Read Stata file into DataFrame.

Parameters:

filepath_or_buffer : string or file-like object Path to .dta file or object implementing a binary read() functions. convert_dates : boolean, defaults to True Convert date variables to DataFrame time values. convert_categoricals : boolean, defaults to True Read value labels and convert columns to Categorical/Factor variables. encoding : string, None or encoding Encoding used to parse the files. None defaults to latin-1. index_col : string, optional, default: None Column to set as index. convert_missing : boolean, defaults to False Flag indicating whether to convert missing values to their Stata representations. If False, missing values are replaced with nan. If True, columns containing missing values are returned with object data types and missing values are represented by StataMissingValue objects. preserve_dtypes : boolean, defaults to True Preserve Stata datatypes. If False, numeric data are upcast to pandas default types for foreign data (float64 or int64). columns : list or None Columns to retain. Columns will be returned in the given order. None returns all columns. order_categoricals : boolean, defaults to True Flag indicating whether converted categorical data are ordered. chunksize : int, default None Return StataReader object for iterations, returns chunks with given number of lines. iterator : boolean, default False Return StataReader object.

Returns:

DataFrame or StataReader

Examples

Read a Stata dta file:

>>> import pandas as pd
>>> df = pd.read_stata('filename.dta')

Read a Stata dta file in 10,000 line chunks:

>>> itr = pd.read_stata('filename.dta', chunksize=10000)
>>> for chunk in itr:
...     do_something(chunk)
