There are a few frequent mistakes individuals make while using Pandas’ pivot function. Here are several illustrations with executable code.
1. Not specifying all required parameters:
You must specify the index, columns, and values when using the pivot function. An error will occur if any of these parameters are left out.
2. Using non-unique values for index/columns combination:
The index and column combination used for pivoting should result in unique values. Using non-unique combinations will lead to errors.
3. Not handling missing values properly:
The pivot function doesn't handle missing values automatically. If there are missing values in the dataset, they need to be handled explicitly.
