Techtalks: Data Science

Yes, in Python, you can obtain an error code from an exception by using the errno attribute of the exception object. The errno attribute is an integer value that represents the error code associated with the exception.

For example, let's say you have a file that you want to open and read in Python. If the file does not exist, attempting to open it will raise a FileNotFoundError exception. You can capture this exception and retrieve the associated error code using the errno attribute, like this:

import errno

try:
    with open('nonexistentfile.txt', 'r') as f:
        content = f.read()
except FileNotFoundError as e:
    print("File not found: ", e)
    print("Error code: ", e.errno)

In this example, if the file "nonexistentfile.txt" does not exist, the open() function will raise a FileNotFoundError exception. The exception is captured in a try-except block, and the error message and error code are printed using the errno attribute. octordle

Note that not all exceptions in Python have an associated error code, and that the errno attribute may not be defined for all exception types. It is important to check the documentation for the specific exception you are working with to determine whether it has an associated error code.

Data Profiling in ETL

The ETL data source is a collection of detailed data. It seeks to understand the structure, value, and significance of information and its relation to other information. This is done through Extraction, Conversion, and Upload (ETL) and helps companies find the information they need for their purposes.

Relational Database (RDBMS)

• RDBMS is a DBMS that enables the organization of aggregated data.
• Relational DBMS is the most widely used database like Oracle, SQL Server. It is characterized by handling data in tables with basic keys that make it possible to identify the rows in each table separately. And an external key that allows you to associate the table with other tables.

OLAP (Online Analytical Processing)

• OLAP is a collection of software tools that provide information to business decision-makers.
• OLAP usually works on a standardized database to facilitate OLAP, not OLTP. These databases are often referred to as data warehouses.
• You can check the comparison and key differences between OLAP vs OLTP here
