PNDSPY1217¶

Message Pandas < pandas.core.strings.accessor.StringMethods.contains > has a partial mapping with a few scenarios not supported in Snowpark.

Category Warning

Description¶

This issue appears when the SMA detects the use of a pandas element that has a direct equivalent in Snowpark pandas, but some scenarios might behave differently than pandas.

Reason: N if the na parameter is set to a non-bool value.

Scenario¶

A method with a few scenarios that aren’t supported in Snowpark.

Input¶

The following example shows a method with a few unsupported scenarios in Snowpark.

import pandas as pd

s = pd.Series(['abc', 'def', 'ghi'])
result = s.str.contains

Copy

Output¶

The SMA adds the EWI PNDSPY1217 to the output code to let you know that this element has a few scenarios that aren’t supported in Snowpark.

import snowflake.snowpark.modin.pandas as pd

#EWI: PNDSPY1217 => pandas.core.strings.accessor.StringMethods.contains has a partial mapping, with few scenarios not supported. Check Snowpark pandas documentation for more detail.
s = pd.Series(['abc', 'def', 'ghi'])
result = s.str.contains

Copy

Recommended fix¶

NULL/NaN handling difference: N if the na parameter is set to a non-bool value.

Snowpark pandas may handle NULL/NaN values differently:

Pre-filter NULL values using .dropna() or .fillna() before the operation
Verify NULL handling behavior with a small sample dataset
Use explicit NULL checks: df[df['column'].notna()]

Additional recommendations¶

Check the Snowpark pandas documentation to verify which scenarios aren’t supported for that specific element.
