‘str’ object has no attribute ‘astype’

The error message ” ‘str’ object has no attribute ‘astype’ ” is raised when you try to use the astype() method on a string object in Python. The astype() method is used to explicitly convert the data type of an object. However, strings are immutable objects in Python, which means their data type cannot be changed directly using this method.

Here’s an example to illustrate the issue:

    
      # Trying to use astype() on a string
      s = "123"
      s.astype(int)
    
  

In the above example, the variable “s” is defined as a string with the value “123”. When we try to use the astype() method to convert it to an integer, the error “AttributeError: ‘str’ object has no attribute ‘astype'” is raised. This is because the astype() method is not available for string objects.

If you want to convert a string to a different data type, you need to use the appropriate conversion function or method for that specific data type. For example, to convert a string to an integer, you can use the int() function:

    
      s = "123"
      i = int(s)
    
  

In this case, the int() function is used to convert the string “123” to an integer. The resulting value of “i” will be 123, which is the expected behavior.
