Convert and Encode Data Types

Convert data types

There are four main ways we can convert the data type of DataFrame columns:

• We can use the astype() function to enforce a pandas dtype.

• We can use the to_ functions like to_datetime() , to_timedelta(), and to_numeric() for manual dtype conversion.

• We can use the apply() function to apply the custom Python function to columns.

• We can use the convert_dtypes() function for automatic dtype inference and conversion.

Lets illustrate these different ways by using a dataset of students’ demographics and academic performance.
