Write a program to enter two integers and perform all arithmetic operations on them.

Write a program to read a list of $n$ integers and find their median.

Note: The median value of a list of values is the middle one when they are arranged in order. If there are two middle values then take their average.

Hint: You can use an built-in function to sort the list

Write a program to read a list of $\mathrm{n}$ integers (positive as well as negative). Create two new lists, one having all positive numbers and the other having all negative numbers from the given list. Print all three lists.

Write a program to read elements of a list.

a) The program should ask for the position of the element to be deleted from the list. Write a function to delete the element at the desired position in the list.

b) The program should ask for the value of the element to be deleted from the list. Write a function to delete the element of this value from the list.

Write a program to read email IDs of $n$ number of students and store them in a tuple. Create two new tuples, one to store only the usernames from the email IDs and second to store domain names from the email IDs. Print all three tuples at the end of the program. [Hint: You may use the function split()]

Write a program that has a user defined function to accept the coefficients of a quadratic equation in variables and calculates its determinant. For example : if the coefficients are stored in the variables $\mathrm{a}, \mathrm{b}, \mathrm{c}$ then calculate determinant as $\mathrm{b}^{2}$-4ac. Write the appropriate condition to check determinants on positive, zero and negative and output appropriate result.
