In this video, we deeply understand the for loop in Python — one of the most important tools for working with data.

Instead of repeating code manually, the for loop allows Python to iterate over items one by one.

In this lesson we cover:

• What a for loop really does
• How Python iterates over iterables
• Using for loop with lists, strings, tuples, and dictionaries
• How iteration works step by step
• Writing clean and readable loops
• Common beginner mistakes

This video connects directly with:

• Iterables in Python
• range() function
• While loops
• Loop control (break & continue)

If you understand for loops clearly, you unlock a major part of Python programming.

This video is part of the Python fundamentals series on PyMLFinance, focused on deep understanding instead of memorizing syntax.

📌 Next videos in the series:
• range() in Python
• While Loop
• Break and Continue
