 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).

Python How to Find Day of the Week

-
DAY of the week Python code you will know here. One is from Calendar, and another one is from a function. Here, I have given my ideas on a better method. Also, the result you can get in a tuple. You might also like Attitude is Everything That Changes Your Life.

Day of Week and Day_Name

  1. Monday 0
  2. Tuesday 1
  3. Wednesday 2
  4. Thursday 3
  5. Friday 4
  6. Saturday 5
  7. Sunday 6
Python: Day of Week How to Calculate
Python: Day of Week How to Calculate

1. Python Logic to get Day of Week from Calendar


from datetime import datetime
import calendar
dt = datetime.today()
dn = dt.weekday()

print("Today is day number: {0}".format(dn))
print("Today is a {0}".format(calendar.day_name[dn]))


Here, the print uses string.format method to print output.


The Output

Python: Day of Week How to Calculate
The result from the first logic


Instead of directly using DateTime, you can write a function - that creates a tuple with Day of week and Day name.

2. Python Logic to get Day and Day_name 

User defined function

from datetime import datetime
from datetime import timedelta
import calendar
def DayOfWeek(d=None):
if d == None:
d = datetime.today()
dn = d.weekday()
return (dn, calendar.day_name[dn])

print(DayOfWeek())
d2 = datetime.today() + timedelta(1)
print(DayOfWeek(d2))


Here, DayOfWeek is a function. You assigned None to d. In the IF, for 'd' and 'dn', you have assigned values. When you Print executes, it returns two values as a tuple.

An object is simply a collection of data (variables) and methods (functions) that act on those data. Similarly, a class is a blueprint for that object.

The Output

Day of week
The result from the second logic

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...
