There are three ways to make a list of the alphabet in Python. 1. Use a for loop to iterate from a to z. 2. Use a list comprehension. 3. Use the String module.
In this tutorial, you'll be examining a couple of methods to get a list of files and folders in a directory with Python. You'll also use both methods to recursively list directory contents. Finally, you'll examine a situation that pits one method against
They are all simple and short so make sure to stick till the end!Using for LoopThe concept is simple. We iterate a for loop until a certain number to generate a list with that number of zeros. Let us see an example.lsz = [] n = 10 for _ in range(n): lsz.append(0) print("...
