4. Who created Python and when
Ans: Python was created by Guido van Rossum and first released in 1991.

5. What are three numeric types in Python.
Ans: Data types in Python include int for integers, float for decimals, str for strings, list for ordered collections, and dict for key-value pairs.

6. What are variables in Python?
Ans: Variables in Python store data values and can be assigned without a specified type.

7. What are some common data types in Python?

9. Name the 2 types of operations to work with strings.
The two types of operations to work with strings are concatenation (joining strings together) and slicing (extracting a portion of a string).

10. What are three numeric types in Python?
Ans: The numeric types in Python are int, float, and complex.

11. What are operators in Python?
Ans: Operators perform operations on variables and values, such as arithmetic operators (+, -, *, /) and comparison operators (==, !=, >, <).

12. What is a pre-defined function? Give an example.
Ans: Pre-defined functions are built-in functions like print(), which output text to the console.

13. How do you call a function in Python?
Ans: To call a function in Python, you use its name followed by parentheses, e.g., function_name().
