3. Write a program using function to calculate the simple interest. Suppose the customer is a senior citizen. She is being offered 15 percent rate of interest; he is being offered 12 percent rate of interest for all other customers, the ROI is 10 percent.

Sample Input:

Enter the principal amount: 200000 Enter the no of years: 3

Gender (m/f): m

Is customer senior citizen (y/n): n Sample Output:

- Create a class Book and initialize it with title, author, and price.

- Create a magic method __eq__, the __eq__ method will check the equality between two objects 

- Create a magic method __ge__, the __ge__ method will check >= relationship with another object. (Only comparing the price attribute) 

- Create a magic method __lt__, the __lt__ method will check < relationship with another object. (Only comparing the price attribute) 

- In all above three magic methods we are comparing two different objects of same class, we need to check / verify here if those objects are from the same class. In all above three magic methods use built-in method isinstance to verify / check if the other object is of same class.

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. 

• Nested lists 
• The “*” operator 
• List slices 
• The “+=” operator 
• A list filter 
• A list operation that is legal but does the "wrong" thing, not what the programmer expects 

Provide the Python code and output for your program and all your examples. 

Write a python program that takes a string as an input from the user and then modifies the string in such a way that the string always starts with an uppercase letter and the case of each subsequent letter is the opposite of the previous letter (uppercase character followed by a lowercase character followed by an uppercase character and so on). Finally the modified string is printed to show the user.

1.      Write a menu driven program to implement of list as a stack containing integers.

iven an integer N  denotes N×N  matrix. Initially, each cell of matrix is empty. U r given K  tasks. In each task, you are given a cell (i,j)  where cell (i,j)  represents

ith  row and jth  column of given matrix.

I/p format

• first line contains two space-separated integers N and K where N is number of rows and columns in given matrix and K is number of tasks respectively.
• Next K lines contain two space-separated integers i and j.

O/p format

Print K space-separated integers denoting numberr of empty cells in matrix.

1. Start off by importing the cars.csv file in the jupyter notebook.

2. Generate a line plot graph for the column ‘model’ and ‘hp’.

a. Map the ‘model’ column on the x-axis.

b. Map the ‘hp’ column on the y-axis.

c. Provide the x-axis label as Models of the cars.

d. Provide the y-axis label as Horse-Power of Cars.

e. Set the title as Model Names vs HorsePower. 

How to find the maximum and minimum from the list by using loops

Write a program that inputs a numerator and denominator then display their quotient and remainder

Sample output:

Enter numerator: 91

Enter denominator: 6

Quotient is: 15

Remainder is: 1

single digit number

input - the input is a single line containing a positive integer N.

output - the output should be a single line containing a single-numeral number.
