Why do we use quotation marks with words but not with numbers?

Good question! The reason we use quotation marks for words (strings) and not for numbers is that quotation marks tell Python that the value inside them should be treated as text, or a string.

For example, when you write `"Python"`, Python knows to treat it as a series of characters, which is a string. On the other hand, writing just `75` without quotes tells Python it's a number, or an integer, which can be used in calculations. So when you're printing or using these values, the quotes help Python distinguish between text and numbers.

Hope this helps! Let me know if you have more questions.
