15 Python Tips : How to Write Code Effectively

Image
 Here are some Python tips to keep in mind that will help you write clean, efficient, and bug-free code.     Python Tips for Effective Coding 1. Code Readability and PEP 8  Always aim for clean and readable code by following PEP 8 guidelines.  Use meaningful variable names, avoid excessively long lines (stick to 79 characters), and organize imports properly. 2. Use List Comprehensions List comprehensions are concise and often faster than regular for-loops. Example: squares = [x**2 for x in range(10)] instead of creating an empty list and appending each square value. 3. Take Advantage of Python’s Built-in Libraries  Libraries like itertools, collections, math, and datetime provide powerful functions and data structures that can simplify your code.   For example, collections.Counter can quickly count elements in a list, and itertools.chain can flatten nested lists. 4. Use enumerate Instead of Range     When you need both the index ...

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
