Spanish Real State IDs

Introduction

The function clean_es_referenciacatastral() cleans a column containing Spanish real state id (Referenciacatastral) strings, and standardizes them in a given format. The function validate_es_referenciacatastral() validates either a single Referenciacatastral strings, a column of Referenciacatastral strings or a DataFrame of Referenciacatastral strings, returning True if the value is valid, and False otherwise.

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

• compact: only number strings without any seperators or whitespace, like “4A08169P03PRAT0001LR”

• standard: Referenciacatastral strings with proper whitespace in the proper places, like “4A08169 P03PRAT 0001 LR”

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_es_referenciacatastral() and validate_es_referenciacatastral().

An example dataset containing Referenciacatastral strings

import pandas as pd
import numpy as np
df = pd.DataFrame(
    {
        "referenciacatastral": [
            "4A08169P03PRAT0001LR",
            "7837301/VG8173B 0001 TT",
            "51824753556",
            "51 824 753 556",
            "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",
            "(staples center) 1111 S Figueroa St, Los Angeles",
            "hello",
        ]
    }
)
df

	referenciacatastral	address
0	4A08169P03PRAT0001LR	123 Pine Ave.

1. Default clean_es_referenciacatastral

By default, clean_es_referenciacatastral will clean referenciacatastral strings and output them in the standard format with proper separators.

from dataprep.clean import clean_es_referenciacatastral
clean_es_referenciacatastral(df, column = "referenciacatastral")

	referenciacatastral	address	referenciacatastral_clean
0	4A08169P03PRAT0001LR	123 Pine Ave.	4A08169 P03PRAT 0001 LR
1	7837301/VG8173B 0001 TT	main st	NaN
2	51824753556	1234 west main heights 57033	NaN
3	51 824 753 556	apt 1 789 s maple rd manhattan	NaN
4	hello	robie house, 789 north main street	NaN
5	NaN	(staples center) 1111 S Figueroa St, Los Angeles	NaN
6	NULL	hello	NaN

2. Output formats

This section demonstrates the output parameter.

standard (default)

clean_es_referenciacatastral(df, column = "referenciacatastral", output_format="standard")

	referenciacatastral	address	referenciacatastral_clean
0	4A08169P03PRAT0001LR	123 Pine Ave.	4A08169 P03PRAT 0001 LR
1	7837301/VG8173B 0001 TT	main st	NaN

4	hello	robie house, 789 north main street	NaN
5	NaN	(staples center) 1111 S Figueroa St, Los Angeles	NaN
6	NULL	hello	NaN

compact

clean_es_referenciacatastral(df, column = "referenciacatastral", output_format="compact")

	referenciacatastral	address	referenciacatastral_clean
0	4A08169P03PRAT0001LR	123 Pine Ave.	4A08169P03PRAT0001LR

3. inplace parameter

This deletes the given column from the returned DataFrame. A new column containing cleaned Referenciacatastral strings is added with a title in the format "{original title}_clean".

clean_es_referenciacatastral(df, column="referenciacatastral", inplace=True)

	referenciacatastral_clean	address
0	4A08169 P03PRAT 0001 LR	123 Pine Ave.

6	NULL	hello	NaN

4. validate_es_referenciacatastral()

validate_es_referenciacatastral() returns True when the input is a valid Referenciacatastral. Otherwise it returns False.

The input of validate_es_referenciacatastral() 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_es_referenciacatastral() only returns the validation result for the specified column. If user doesn’t specify the column name, validate_es_referenciacatastral() returns the validation result for the whole DataFrame.

from dataprep.clean import validate_es_referenciacatastral
print(validate_es_referenciacatastral("4A08169P03PRAT0001LR"))
print(validate_es_referenciacatastral("7837301/VG8173B 0001 TT"))
print(validate_es_referenciacatastral("51824753556"))
print(validate_es_referenciacatastral("51 824 753 556"))
print(validate_es_referenciacatastral("hello"))
print(validate_es_referenciacatastral(np.nan))
print(validate_es_referenciacatastral("NULL"))
