> Reporter: Keerthan Harish Vasist
> Assignee: Keerthan Harish Vasist

> In functions.py, there is a function added {{def column(col)}}. There is also
> another method in the same file {{def col(col)}}. This leads to some
> ambiguity on whether the parameter is being referred to or the function. In
> pyspark 3.1.2, this leads to {{TypeError: 'str' object is not callable}} when
> the function {{column(col)}} is called - the highest preference is given to
> the string variable in scope as opposed to the function {{col }}in the file
> as intended.
> This PR fixes that ambiguity by changing the variable name to {{col_like}}.
>
> I have already raised a PR to fix the issue -
> https://github.com/apache/spark/pull/32771
