Python Lists, Tuples and Plotting
This video provides an introduction to Python sequences with a focus on lists and tuples. I begin by distinguishing lists from tuples and explaining why mutability matters. Next, I practice core operations, indexing, slicing, iteration, and common list methods. I then introduce safe copying techniques, list comprehensions, and two-dimensional lists. A brief file I/O example demonstrates reading from and writing to text files. I conclude with data visualization in Matplotlib, creating line, bar, and pie charts to present results clearly.
