 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.

Here are two examples to unpack a list in Python. You can do it easily by using splat operator. The asterisk in python is called a Splat operator. Here are two splat operators - Single and Double. Below, you will find examples. 1. Single splat operator Consider, for example, this code: abc = [1,2,3,4] print(abc)  Here the output will be: [1, 2, 3, 4] What if you didn't want the list output in list format? What if all you wanted was the list of values to be written to the output console? You could write them using a loop and one of the output functions, but Python prefers an easier way: print(*abc) 1 2 3 4 2. Double splat operator Here, I have written a function: def func(x,y,z):        return x + y + z print(func(**d)) It will show '6' as output. Since, I have assigned values for x,y, and z in a dictionary. So by using a double splat operator you assign values to the function. d = {  'x': 1,  'y': 2,  'z': 3  } Related posts 3 Advanced m...
