6. Medical Discussion Forum (www.breastcancer.org, www.homeopathyworldcommunity.com,

www.abchomeopathy.com) and perform the following task:



b. Separate the individual sentence into separate line (The sentences must be in separate

new line but dont give more than one line space)

c. Separate the individual word into separate line (The words must be in separate new line

but dont give more than one line space and the punctuations marks are also must be in

separate new line)

7. Write a program that calculates and prints the value according to the given formula:

Q = Square root of [(2 * C * D)/H]

Following are the fixed values of C and H: C is 50, H is 30, D is the variable whose values

should be input to your program in a comma-separated sequence.

Example:

Let us assume the following comma separated input sequence is given to the program:

100,150,180

The output of the program should be:

18, 22, 24

8. Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The

element value in the i-th row and j-th column of the array should be i*j.

Note: i=0,1.., X-1; j=0,1,.,Y-1. Example:

Suppose the following inputs are given to the program:

3,5

Then, the output of the program should be:

[[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]]

9. Write a function char_freq_table() that, when run in a IDLE, accepts a file name from the user,

builds a frequency listing of the characters contained in the file, and prints a sorted and nicely

formatted character frequency table in another file.

10. Write a program, which will find all such numbers between 0 and 3000 (both included) such

that each digit of the number is an even number.

The numbers obtained should be printed in a comma-separated sequence in a file.

11. Write a program that accepts a sentence and calculate the number of letters and digits.

Suppose the following input is supplied to the program:

hello world! 123

Then, the output should be:

LETTERS 10

DIGITS 3

12. Write a program that computes the net amount of a bank account based a transaction log

from console input. The transaction log format is shown as following:

D 100

W 200

D means deposit while W means withdrawal.


D 300

D 300

W 200

D 100


500

13. A website requires the users to input username and password to register. Write a program to

check the validity of password input by users.

Following are the criteria for checking the password:

1. At least 1 letter between [a-z]

2. At least 1 number between [0-9]

1. At least 1 letter between [A-Z]

3. At least 1 character from [$#@]

4. Minimum length of transaction password: 6

5. Maximum length of transaction password: 12

Your program should accept a sequence of comma separated passwords and will check them

according to the above criteria. Passwords that match the criteria are to be printed, each

separated by a comma.

Example

If the following passwords are given as input to the program:

ABd1234@1,a F1#,2w3E*,2We3345


ABd1234@1

14. Write a program to compute the frequency of the words from the input. The output should

output after sorting the key alphanumerically.

15. Define a function which can print a dictionary where the keys are numbers between 1 and 20

(both included) and the values are square of keys. Print the dictionary (key value) in separate file.

16. Define a class named Rectangle which can be constructed by a length and width. The

Rectangle class has a method which can compute the area.

17. Define a class named Shape and its subclass Square. The Square class has an init function

which takes a length as argument. Both classes have a area function which can print the area of

the shape where Shape's area is 0 by default.

18. Write a function that takes a character (i.e. a string of length 1) and returns True if it is a

vowel, False otherwise.

19. Define a function is_palindrome() that recognizes palindromes (i.e. words that look the same

written backwards). For example, is_palindrome("madam") should return True.

20. Write a program to solve a classic ancient Chinese puzzle:

We count 35 heads and 94 legs among the chickens and rabbits in a farm. How many rabbits and

how many chickens do we have? (Hint: Use for loop to iterate all possible solutions)

21. Write a program which accepts a string from console and print the characters that have even

indexes.

Example:

If the following string is given as input to the program:

H1e2l3l4o5w6o7r8l9d


Helloworld

22. Define a class Person and its two child classes: Male and Female. All classes have a method

"getGender" which can print "Male" for Male class and "Female" for Female class.

23. Write a program to generate all sentences where subject is in ["I", "You"] and verb is in

["Play", "Love"] and the object is in ["Hockey","Football"].

24. Assuming that we have some email addresses in the "[email protected]"

format, write program to print the company name of a given email address. Both user names and

company names are composed of letters only.

Example:

If the following email address is given as input to the program:

[email protected]


google

In case of input data being supplied to the question, it should be assumed to be a console input.

25. Write program to design a general calculator.

26. Write a program to calculate your age in the format (yy(years)/mm(months)/dd(days)). The

input will be your DOB(yyyy/mm/dd) and present date (yyyy/mm/dd).
