Python programme comparing for and while loops, Python Programming

1)    Write a python programmecomparing for and while loops like the following.

Math Times table

For Loop:





While Loop:





2)    Write a program that simulates the Math method 'pow'. The program will read real Values as input and calculate the value as power of the input value (Use math library). This will then output to screen as following two examples:

Input of 3, should return 9.

Input of 4, should return 16.         

3)    Write a programme that calculates:

a)    How much an amount deposited in a bank account at r% annual interest has grown to after one, two and three years.

b)    The general formula for computing the amount including after n years is: Kn= k0 *(1+r/100)n

4)    Create a dog years programme to calculate the number of human years corresponds to the dog's age. The programme with accept the age of the dog as an input.

a)    A one year old dog roughly corresponds to 14 years old child.

b)    A dog that is two years old corresponds to 22 years old human.

c)    Every further dog year corresponds to five human years.


Enter the age of the dog: 5

The human age in years is 37

5)    Write a program that reads a sequence of integers from a file and prints a frequency report showing how many times the integers 0 to 9 occurs in the sequence.

Example of input data is 4, 5, 4, 2, 8, 9, 1, 0, 3, 6, 8, 9, display the number of occurrence for each integers from 0 to 9.

6)    Write a program that reads a line of text from the keyboard, and display after replacing each occurrence of any four-letter word in the text with the word "x***", where x is the first character in the four-letter word.

Example:Input : "This apple tree is the best"

Display output: "T*** apple t*** is the b***"

7)    Write a class Employee that stores the employee number, name, position and salary. Include the Constructor, Accessor and Mutator methods.No output required.

8)    Include in the question 8 the four methods, the following methods to reset salary, increase and decrease the salary and to print the current salary. No output required.

9)   Write a program that uses paired array. The task is to match the grade with the cutoff percentage mark.

a)    The first list (array) represents all the student grades (F2, F1, P1, P2, C, D, HD)

b)    The second list (array) holds the corresponding cutoff percentage mark required (45, 50, 55, 60, 65, 75, 85).

c)    The program should prompt and read a percentage value as input.

d)    The corresponding grade is output to the screen.

10) Write a program that reads a list of twenty integers from a file and stores them in an array.

a)    The program should print the position of the smallest number in the array.

b)    If the position of the smallest number is other than 0, the program should swap the number in position 0 with the smallest value.

c)    After swapping, the smallest number is now in position 0 and the number that was previously in position 0 is now where the smallest number was.

d)    Finally the program should print the values in the array.
