[via GitHub]

albertoRamon opened a new issue, #1176:
URL: https://github.com/apache/datafusion-python/issues/1176

   **Describe the bug**
   There is a small typo in this manual: [Case 
Builder](https://datafusion.apache.org/python/autoapi/datafusion/expr/index.html#datafusion.expr.CaseBuilder)
 with the brackets 
   
       f.case(col("column_a"**))**  ##Here
       .when(lit(1), lit("One"))
       .when(lit(2), lit("Two"))
       .otherwise(lit("Unknown"))
   
   _AttributeError: 'Expr' object has no attribute 'when'_
   
   
   **To Reproduce**
   `from datafusion import SessionContext, col, lit, functions as f
   ctx = SessionContext()
   
   # Create sample data
   data = {"col_a": [1, 1, 2, 2, 2], "col_b": [10, 20, 30, 40, 50]}
   df = ctx.from_pydict(data)
   
   df=df.select(
       f.case(col("col_a"))
       .when(lit(1),lit("one"))
       .when(lit(2),lit("two"))
       .otherwise(lit("Unknown")).alias("f_case")
       )
   
   df.show()`
   
   **Expected behavior**
   <NA>
   
   **Additional context**
   <NA>
