Summing and Averaging Python Lists and Tuples

📊 Summing & Averaging Sequences in Python | sum(), mean(), and More! In this tutorial, you'll learn multiple ways to sum and average values in Python sequences like lists and tuples — a foundational skill for anyone working with data in Python! 🔹 What you'll learn: ✅ Using the built-in sum() function (with optional start values) ✅ Calculating averages manually with sum() / len() ✅ Safely handling empty sequences (avoiding division-by-zero errors) ✅ Filtering and conditionally summing/averaging with list comprehensions ✅ Using statistics.mean() for clean, readable averaging Whether you're a Python beginner or brushing up on the basics for data science, this video covers practical, real-world examples you can apply directly to your own code. 💻 Code examples covered: sum(my_list) and sum(my_list, start) average = sum(sequence) / len(sequence) Conditional sums using generator expressions statistics.mean() Timeline: 0:00 Introduction 0:07 Summing using sum() function 1:12 Calculating average 1:52 Using list comprehension 3:55 Using mean() function from statistics module 👍 If this helped you, please like, comment, and subscribe for more Python and Data Science tutorials! 🔔 Turn on notifications so you don't miss the next video in this series. #python #PythonProgramming #LearnPython #PythonTutorial #DataScience #CodingTutorial #PythonForBeginners #PythonBasics #PythonLists #PythonTips #StatisticsModule #CodeNewbie #ProgrammingTutorial #PythonDataScience #PythonEducation
