Learning PySpark: Joining DataFrames with Mismatched Column Names

The process of integrating disparate datasets is fundamental to modern data analysis and engineering. When working with PySpark, joining two or more DataFrames is a routine operation. However, a common challenge arises when the corresponding linking columns in the source DataFrames possess different names. Standard join syntax requires identical column names, which necessitates a preparatory
