snowflake.snowpark.functions.initcap(e: Union[Column, str], delimiters: Optional[Union[Column, str]] = None) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.16.0/src/snowflake/snowpark/functions.py#L2109-L2134)

Examples:

>>> df = session.create_dataframe(["the sky is blue", "WE CAN HANDLE THIS", "ÄäÖößÜü", None], schema=["a"])
>>> df.select(initcap(df["a"]).alias("initcap")).collect()
[Row(INITCAP='The Sky Is Blue'), Row(INITCAP='We Can Handle This'), Row(INITCAP='Ääöößüü'), Row(INITCAP=None)]
>>> df.select(initcap(df["a"], lit('')).alias("initcap")).collect()
