Python-Modifying-Data-in-Pandas

In this project, we modified the data using the Pandas library. We implement all changes over the file big_mart_sales.csv. The techniques we used to improve our data set are:

1. How to impute missing values in any columns ?
2. How to change incorrectly entered values for a specific column: map () function?
3. How to change the value of a column using the apply () function?
4. How to create a new column based on an existing column?
5. How to convert categorical variables to numerical ?
