Image
 Here are some key terms commonly used in data pipelines 1. Data Sources Definition: Points where data originates (e.g., databases, APIs, files, IoT devices). Examples: Relational databases (PostgreSQL, MySQL), APIs, cloud storage (S3), streaming data (Kafka), and on-premise systems. 2. Data Ingestion Definition: The process of importing or collecting raw data from various sources into a system for processing or storage. Methods: Batch ingestion, real-time/streaming ingestion. 3. Data Transformation Definition: Modifying, cleaning, or enriching data to make it usable for analysis or storage. Examples: Data cleaning (removing duplicates, fixing missing values). Data enrichment (joining with other data sources). ETL (Extract, Transform, Load). ELT (Extract, Load, Transform). 4. Data Storage Definition: Locations where data is stored after ingestion and transformation. Types: Data Lakes: Store raw, unstructured, or semi-structured data (e.g., S3, Azure Data Lake).

6 Python file Methods Real Usage

-
Files always have data in them. For different purposes, you need methods to deal with them. These six file methods of use in this case.


Related: 5 top file modes in python.


Python file methods

Python file methods

Below are the top six file methods in python:
  1. Tell()
  2. Seek()
  3. Flush()
  4. Fileno()
  5. truncate()
  6. isatty()

1. tell()


The usage of tell method is it returns the cursor-position of the file-pointer from the beginning of the file. It tells the current cursor position. The position starts from zero, which is same as of an index.


Syntax: 

fileobject.tell()


2. seek()


The usage of seek method is cursor position, from one position to the specified position from the beginning of the file, it moves. Here, the cursor will be sought to a particular location.

Syntax: 

fileobject.seek(position)


3. flush()


The usage of flush method is clean out the internal buffer. Before writing the text in the file, it is best practice to clear out that the internal buffer can be cleared.

Syntax: 

fileobject.flush()


4. fileno()


The usage of  fileno method is file-number i.e. a file descriptor as an integer value it returns. If an operating system does not use a file descriptor of the file then an error may occur.

Syntax: 

fileobject.fileno()


5. truncate()


The usage of truncate method is on the given number of bytes it resizes the file. The current position will be used if the size is not specified.

Syntax: 

fileobject.truncate(size)


6. isatty()

The usage of isatty method is Boolean. True if the file is connected to an end device like (tty) device else will return False.

Syntax:

fileobject.isatty()

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same.

During the import of my python script, I got the import error cannot import name datetime. My Script: datetime.py My script's intention is to find whether the minute value is odd or not. Python Logic from datetime import datetime odds = [ 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 , 17 , 19 , 21 , 23 , 25 , 27 , 29 , 31 , 33 , 35 , 37 , 39 , 41 , 43 , 45 , 47 , 49 , 51 , 53 , 55 , 57 , 59 ] right_this_minute = datetime.today().minute if right_this_minute in odds: print ( "This minute seems a little odd." ) else : print ( "Not an odd minute." ) ImportError I have imported my datetime.py from Linux. It gives an error ...

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
