15 Python Tips : How to Write Code Effectively

 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 and the value in a loop, enumerate is a more Pyth

How to Find Max and Min Quickly in Python List

-
Here's logic to find Max and Min values in a List. Without using built-in Max() and Min () functions you can find Max and Min values in a List. For that matter, you need to write a user-defined function. This post is all about how to write it and run.

Finding Max and Min in List


You can achieve this by writing a user-defined function. Here's useful logic and steps to write it precisely.


IN THIS PAGE

  • Write a Function
  • Execute Function
  • Get the result
  • Write Function

You can write an user-defined function to get MAX and MIN values. In this function, I am using the max(), min() built-in functions. The other variables you can use as you wish. Below is the my actual logic.


Python Function to find Maximum and Minimum Easily


Sample Code

def findmaxmin(data): 
ax = max(data) 
by = min(data) 
return(x,y)
data = (109, 98, 88, 7) 
(maximum, minimum) = findmaxmin (data) 
print("Maximum Marks = ", maximum) 
print("Minimum Marks = ", minimum)


Created a Script Using vim editor

Here as the first step, I have written the maxmin.py file in Ubuntu. The function name is  "findmaxmin ".

define function using input arguments

Result


Below command to enter Python. This command, you can issue in Ubuntu where python3 is installed

$ python3

You have now entered Python3.

>>> import maxmin

You will prompt a message that imported successfully without any syntax errors.

Code in the Python Script


How to import python script and run


Below commands, I have issued.

>>> data = (109, 98, 88, 7)
>>> maxmin.findmaxmin(data)


The result is (109, 7)

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 or

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)             print(square, cube) Here, in print, it returns two variables.
