                                                                      File handling in Python File handling in Python allows you to work with files on your computer's storage. You can open files, read data from them, write data to them, and close them when you're done.  This is useful for tasks like r eading text files, writing logs , or processing data stored in files. "r": Open for reading (default). Raises FileNotFoundError if the file doesn't exist. " w": Open for writing. Creates a new file if it doesn't exist, overwrites the existing content if it does. "a": Open for appending. Creates a new file if it doesn't exist. Writes to the end of the file if it does. "b": Binary mode. Appends "b" to other modes (e.g., "rb", "wb") to indicate binary mode. "+": Open for updat...

                                                                Mastering List Comprehensions List comprehensions are a concise and powerful way to create lists in Python. They provide a compact syntax for generating lists based on existing iterables like lists, strings, or range objects List comprehensions syntax: expression is the expression to be evaluated for each item in the iterable. item is the variable representing each element in the iterable. iterable is the iterable object (list, string, range) used to generate the elements. Example: Consider the task of creating a list containing squares of numbers from 1 to 5 using a traditional loop and then with a list comprehension. In the list comprehension [i*i for i in range(1, 6)], we iterate over each ele...
