"""Uses the Data Loss Prevention API to de-identify sensitive data in a
table by replacing them with fixed size bucket ranges.
Args:
project: The Google Cloud project id to use as a parent resource.
table_data: Dictionary representing table data.
deid_content_list: A list of fields in table to de-identify.
bucket_size: Size of each bucket for fixed sized bucketing
(except for minimum and maximum buckets). So if ``bucketing_lower_bound`` = 10,
``bucketing_upper_bound`` = 89, and ``bucket_size`` = 10, then the
following buckets would be used: -10, 10-20, 20-30, 30-40,
40-50, 50-60, 60-70, 70-80, 80-89, 89+.
bucketing_lower_bound: Lower bound value of buckets.
bucketing_upper_bound: Upper bound value of buckets.
Returns:
De-identified table is returned;
the response from the API is also printed to the terminal.
Example:
>> $ python deidentify_table_bucketing.py \
'{"header": ["email", "phone number", "age"],
