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...

Python Tuple: Here're 2 Ways to Calculate Sum Easily

Python tuple is nothing but a set of data. It can have an 'n' number of elements. Here, in my example, the tuple has 20 Elements. The below logic helps you to calculate the sum of its 20 Elements easily. 

A tuple is simply a set, and it can have both positive and negative Elements. So, don't worry. You can calculate the sum even the tuple has negative numbers.

How to calculate tuple sum in Python


Here are 2 Ways You can calculate Sum

  1. Display sum after adding each element
  2. Display sum at once  

Python Logic: #1 Method - The Print Displays Sum in Vertcle after Adding Each Element

my_tuple = (1,20, -30, 50, 10, 11, 6, 7, 22, 88, 10, 20, 565, 121, 211, 5, 2, 18, 20, 21)

sum = 0

for index in my_tuple:

         sum = sum+ index

        print("sum of elements:", sum)

Note*** Here the print statement is within the For Loop.

sum = 0

for index in my_tuple:

         sum = sum+ index

print("sum of elements:", sum)

Note*** Here the print statement is outside of the For Loop.
