The astype() method in the Pandas library is a powerful tool for changing the data type of a Pandas DataFrame or Series. This method is particularly useful when you need to convert the data type of one or more columns to facilitate various data manipulation and analysis tasks.
In this tutorial, we will cover the basics of the astype() method, its parameters, and provide practical examples to illustrate its usage.
The basic syntax of the astype() method is as follows:
In this example, the 'Numbers' column is initially of integer type, and we use astype(float) to convert it to float.
In this example, the 'Values' column contains a mix of integers and strings. By using astype(int, errors='coerce'), we try to convert the values to integers. The 'coerce' option replaces non-convertible values with NaN.
