3. What are the possible loop values that can be specified in the range argument of a for loop in Python, and why are these values used?

- Integers, representing the starting and ending points of the loop, allowing iteration through a specified range of numbers.
- Floating-point numbers, enabling iteration through decimal ranges with precise steps.
- Strings, facilitating iteration through characters in a specified string
- Tuples, allowing iteration through multiple sequences simultaneously.

4. What values can be used in the argument of a while loop in Python, and why are these values used?

- Integers, representing the starting and ending points of the loop, allowing iteration through a specified range of numbers
- Boolean expressions or conditions, enabling the loop to execute until the condition becomes False.
- Floating-point numbers, allowing iteration through decimal ranges with precise steps.
- Strings, facilitating iteration through characters in a specified string.

5. What types of conditional entries can be used in a Python **if **statement, and why are these entries used?

- Integers, representing specific numeric values to check against a variable, ensuring a match for equality
- Boolean expressions or conditions, evaluating to True or False and determining the path of execution in the code.
- Strings, enabling comparison of text values for exact matches in the condition
- Floating-point numbers, allow range-based conditions to check if a variable falls within a specific numerical range.
