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 ...

Python Interface Vs. Class: What's the Difference

-
Here are the differences between Class and Interface in Python.

Python interface


Python class can have all concrete methods. But interface does not have single concrete method.


Here you'll know about

  • What's abstract method
  • Abstract Class: How to Create it
  • Rules to Write an Interface
  • How to Create Abstract Class
  • How to Create an Interface


What's abstract method

The abstrcat method is one which does not have body.

from abc import ABC, abstract method
class name_class(ABC): # abstract class

@abstractmethod
def name_method(self): #abstract method without body
pass


The interface is used when all the features are needed to be implemented differently for different objects.

Rules to Write an Interface

  1. All methods of an interface should be abstract.
  2. You cannot create an interface object.
  3. If any class implements an interface, then you need to define all the methods given in that interface in child class.
  4. You need to declare all methods as abstract if that class does not implement the interface

How to Create Abstract Class


from abc import ABC, abstractmethod
class Myengineer(ABC):
@abstractmethod
def mybranch(self):
pass
myobj = Myengineer()


Output

TypeError: Can’t instantiate abstract class Myengineer
with abstract methods mybranch


How to Create an Interface

You cannot create an object from an abstract class. But you can do it by creating a child class.


from abc import ABC, abstractmethod

#Abstract class

class Myengineer(ABC):
@abstractmethod
def mybranch(self):
pass

#Child class implements abstract class

class MyEEE(Myengineer):
def mybranch(self):
print(“I am an electrical and electronics Engineer”)
myobj = MyEEE()
myobj.mybranch()

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same. I'll show you how this error happens and its resolution.   Here's the Resolution for ImportError I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. 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

-

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...

What is placeholder in Python? The purpose of it is to mask the variable that you don't want to use in a function. In python, y ou can call the underscore ( _ ) operator placeholder. Below, you'll find how to use single and double placeholders in a function. What is placeholder in python The purpose of placeholder in Python is to mask variables that you don't want to use in a function. So that your code will be readable. Moreover, in future, if you want to use those variables you can replace the placeholders with the names you want. In This Page You'll know in three steps how to use placeholder correctly. Creating a function Logic to use single placeholder Logic to use two placeholders 1. Creating a function. def function_that_returns_multiple_values(x):        return x*2, x*3, x+1        for i in range(0,5):             square, cube, added_one = function_that_returns_multiple_values(i)      ...
