The Easy Way to Split String Python Partition Method

-

Here's a way without the Split function you can split (or extract) a substring. In Python the method is Partition. You'll find here how to use this method with an example. 


Split string using the Partition

How to Split the string using Partition method

 

Returns Left side part

Example-1

my_string='ABCDEFGH||10||123456.25|'

my_partition=my_string.partition('|')[0]

print(my_partition)


Output

|10||123456.25|


** Process exited - Return Code: 0 **
Press Enter to exit terminal

Example-2

Returns from the separator to last of the string.

my_string='ABCDEFGH||10||123456.25|'
my_partition=my_string.partition('|')[-1]
print(my_partition)

Output

|10||123456.25|


** Process exited - Return Code: 0 **
Press Enter to exit terminal


The use of Rpartition to split a string in Python


Example-1

Returns except right side last separator.

my_string='ABCDEFGH||10||123456.25|'
my_partition=my_string.rpartition('|')[0]
print(my_partition)

Output

ABCDEFGH||10||123456.25


** Process exited - Return Code: 0 **
Press Enter to exit terminal

Example-2

Returns no string

my_string='ABCDEFGH||10||123456.25|'
my_partition=my_string.rpartition('|')[-1]
print(my_partition)


Output




** Process exited - Return Code: 0 **
Press Enter to exit terminal

Step-by-Step Guide to Reading Different Files in Python

-
Image
 In the world of data science, automation, and general programming, working with files is unavoidable. Whether you’re dealing with CSV reports, JSON APIs, Excel sheets, or text logs, Python provides rich and easy-to-use libraries for reading different file formats. In this guide, we’ll explore how to read different files in Python , with code examples and best practices. 1. Reading Text Files ( .txt ) Text files are the simplest form of files. Python’s built-in open() function handles them effortlessly. Example: # Open and read a text file with open ( "sample.txt" , "r" ) as file: content = file.read() print (content) Explanation: "r" mode means read . with open() automatically closes the file when done. Best Practice: Always use with to handle files to avoid memory leaks. 2. Reading CSV Files ( .csv ) CSV files are widely used for storing tabular data. Python has a built-in csv module and a powerful pandas library. Using cs...

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...
