Greek Social Security Numbers¶

Introduction¶

The function clean_gr_amka() cleans a column containing Greek social security number (AMKA) strings, and standardizes them in a given format. The function validate_gr_amka() validates either a single AMKA strings, a column of AMKA strings or a DataFrame of AMKA strings, returning True if the value is valid, and False otherwise.

AMKA strings can be converted to the following formats via the output_format parameter:

compact: only number strings without any seperators or whitespace, like “01013099997”
standard: AMKA strings with proper whitespace in the proper places. Note that in the case of AMKA, the compact format is the same as the standard one.
birthdate: split the date parts from the number and return the birth date, like “1930-01-01”.
gender: get the person’s birth gender (‘M’ or ‘F’).

Invalid parsing is handled with the errors parameter:

coerce (default): invalid parsing will be set to NaN
ignore: invalid parsing will return the input
raise: invalid parsing will raise an exception

The following sections demonstrate the functionality of clean_gr_amka() and validate_gr_amka().

An example dataset containing AMKA strings¶

[1]:

import pandas as pd
import numpy as np
df = pd.DataFrame(
    {
        "amka": [
            '01013099997',
            '01013099999',
            '7542011030',
            '7552A10004',
            '8019010008',
            "hello",
            np.nan,
            "NULL",
        ],
        "address": [
            "123 Pine Ave.",
            "main st",
            "1234 west main heights 57033",
            "apt 1 789 s maple rd manhattan",
            "robie house, 789 north main street",
            "1111 S Figueroa St, Los Angeles, CA 90015",
            "(staples center) 1111 S Figueroa St, Los Angeles",
            "hello",
        ]
    }
)

7	NULL	hello	NaN

4. `validate_gr_amka()`¶

validate_gr_amka() returns True when the input is a valid AMKA. Otherwise it returns False.

The input of validate_gr_amka() can be a string, a Pandas DataSeries, a Dask DataSeries, a Pandas DataFrame and a dask DataFrame.

When the input is a string, a Pandas DataSeries or a Dask DataSeries, user doesn’t need to specify a column name to be validated.

When the input is a Pandas DataFrame or a dask DataFrame, user can both specify or not specify a column name to be validated. If user specify the column name, validate_gr_amka() only returns the validation result for the specified column. If user doesn’t specify the column name, validate_gr_amka() returns the validation result for the whole DataFrame.

[10]:

from dataprep.clean import validate_gr_amka
print(validate_gr_amka('01013099997'))
print(validate_gr_amka('01013099999'))
print(validate_gr_amka('7542011030'))
print(validate_gr_amka('7552A10004'))
print(validate_gr_amka('8019010008'))
print(validate_gr_amka("hello"))
print(validate_gr_amka(np.nan))
print(validate_gr_amka("NULL"))
