str.len() is used to determine the length of each line in a row pandas This method is only for a sequence of lines.
Since this is a string method, you must add the prefix .str before calling this method. Otherwise it will give an error.
Return type: Series of integer values. NULL values might be present too depending upon caller series.

In the following examples, the data frame used contains data for some NBA players. An image of the data frame before any operations is attached below.
Example # 1: Calculating the length of a row of lines (dtype = str)
This example computes the row length of the Name column using the str.len () method. D Series is already a string. Thus, there is no need for data type conversion. Zero lines are removed before any operations are performed to avoid errors.
As shown in the output image, the length of each row in the name column is returned.
Example # 2:
In this example, the length of the salary column is calculated using the str.len ( ). Since the batch is imported as a float64 dtype, it is first converted to a string using the .astype () method.
As shown in the output, the length of an int or float series can only be calculated by converting it to a string of type d.
