Attributeerror: ‘str’ object has no attribute ‘astype’

AttributeError: ‘str’ object has no attribute ‘astype’

This error occurs when trying to use the astype method on a string object. The astype method is used to cast the data type of a pandas series or dataframe, but it is not available for string objects.

Here’s an example to demonstrate this error:

# Import pandas
import pandas as pd

# Create a dataframe
df = pd.DataFrame({'A': ['1', '2', '3']})

# Try to cast the 'A' column to integer
df['A'].astype(int)  # This line throws the error

In this example, we are trying to convert the values in the ‘A’ column from string to integer. However, the astype method cannot be used on string objects, leading to the AttributeError.
