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.

filepath_or_buffer : str, path object or file-like object

Any valid string path is acceptable. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: file://localhost/path/to/table.dta.

If you want to pass in a path object, pandas accepts any os.PathLike.

By file-like object, we refer to objects with a read() method, such as a file handler (e.g. via builtin open function) or StringIO.

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.

DataFrame or StataReader
