Pyarrow.lib.arrowtypeerror: object of type cannot be converted to int

Explanation:

The error message “pyarrow.lib.arrowtypeerror: object of type ‘str’ cannot be converted to int” indicates that there is an attempt to convert a string (str) object to an integer (int) using PyArrow library, which is not possible. To understand this error better, let’s take a look at the following example:

      import pyarrow
      
      # Attempting to convert a string to an integer
      value = "123"
      result = pyarrow.int64(value)
   

In this example, the variable ‘value’ is assigned a string “123”. And we try to convert this string to an integer using the pyarrow.int64() function. However, this conversion is not possible because strings represent textual data and integers represent numerical data. Therefore, PyArrow raises the mentioned ArrowTypeError.

To resolve this error, you need to ensure that you are appropriately handling the data types. If you want to convert a string to an integer, you can use the built-in int() function in Python. Here’s an updated example:

      # Converting string to integer
      value = "123"
      result = int(value)
   

In this updated example, the variable ‘value’ is still a string “123”. However, we use the int() function instead of PyArrow’s int64() function to convert it to an integer. The int() function in Python can handle string-to-integer conversions without any issues.
