keerthanvasist opened a new pull request #32771:
URL: https://github.com/apache/spark/pull/32771
### What changes were proposed in this pull request?
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`.

`column()` function is called. This Pr fixes that error.
