1.Create a variable named name and assign your name to it. Then print the value of the variable.
2.Create a variable age and assign your age to it. Later, reassign the variable with a new value and print the new value.
3.Assign the values 5, 10, and 15 to three variables a, b, and c in a single line. Print their values.
Ans:TypeError on 4th statement, because we're trying to concatenate integers (a, b, c) with strings
4.Swap the values of two variables x and y without using a third variable. Print their values before and after swapping.
5.Define constants PI with appropriate values and print them.
Ans: constants are typically written in all uppercase letters with underscores separating words. However, Python does not enforce this, so constants are not truly immutable. You can still override.
6.Write a program that calculates the area of a circle using the constant PI and a variable radius. Print the area.
Ans: ** is Squared
7.Define constants for the length and width of a rectangle. Calculate and print the area.
8.Define a constant for π (pi) and a variable for the radius. Calculate and print the circumference of the circle.
