Data Science and Machine Learning (Theory and Projects) A to Z - Control Flow in Python: Else in For Loop

The video tutorial explains the use of the else clause in Python for loops, which executes only if the loop completes all iterations without encountering a break statement. Examples using sets and dictionaries are provided to illustrate the concept. The tutorial also advises caution when using else with for loops to avoid confusion with if-else statements. Practical examples are demonstrated in Jupyter Notebook, and the video concludes with a brief overview of the next steps in learning Python loops.
