How to Use For Loops and Iterate Over Data in Python

In this session, you’ll learn how to use for loops in Python to iterate over data and automate repetitive tasks. This lesson covers loop syntax, iterating over different data structures, nested loops, file handling, and common list operations used in data analysis workflows. You’ll learn how data analysts use loops to process datasets, read and write files, handle multiple files, and apply logic repeatedly across data. Key Takeaways Understand how for loops work in Python Learn how to iterate over sequences such as lists, tuples, and sets Understand loop syntax and the role of the loop variable Learn how to read from and write to files using open() Learn how to extract lines from files using readlines() Learn how to save processed data Understand how nested loops work Learn how to append values to lists Learn how to use glob to handle file path patterns Chapters 00:00 Introduction to for loops in Python 06:40 Loop syntax and iterating over sequences 18:30 Iterating over lists, tuples, and sets 32:10 Understanding loop variables 45:20 Nested loops explained 58:30 Introduction to file handling with open() 1:10:40 Reading and writing files 1:22:30 Extracting lines using readlines() 1:32:40 List operations and append() 1:40:30 Using glob for file path patterns 1:47:40 Summary and next steps Q&A Q: What is a for loop in Python? A: A for loop allows you to repeat an action for each item in a sequence. Q: What does “for item in sequence” mean? A: It means the variable item takes the value of each element in the sequence one at a time. Q: What are nested loops? A: Nested loops are loops placed inside other loops to handle multi-level iteration. Q: How do data analysts use loops? A: Data analysts use loops to process data, automate tasks, and work with files and datasets. Q: What is glob used for in Python? A: glob is used to match and work with multiple file paths using patterns.
