Question 1:
Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,
between 2000 and 3000 (both included).
The numbers obtained should be printed in a comma-separated sequence on a single line.
Hints:
Consider use range(begin, end) method
Solution :
a = [] for i in range(2000, 3001): if (i%7==0) and (i%5!=0): a.append(str(i)) print(','.join(a))
Question 2 :
Write a program which can compute the factorial of a given numbers.
The results should be printed in a comma-separated sequence on a single line.
Suppose the following input is supplied to the program:
8
Then, the output should be:
40320
Solution :
def fact(x): if x == 0: return 1 return x * fact(x - 1) x=int(input("Enter Number: ")) print(fact(x))
Question 3 :
With a given integral number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary.
Suppose the following input is supplied to the program:
8
Then, the output should be:
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Consider use dict()
Solution :
n=int(input()) a=dict() for i in range(1,n+1): a[i]=i*i print(a)
Question 4 :
Write a program which accepts a sequence of comma-separated numbers from console and generate a list and a tuple which contains every number.
Suppose the following input is supplied to the program:
34,67,55,33,12,98
Then, the output should be:
[’34’, ’67’, ’55’, ’33’, ’12’, ’98’]
(’34’, ’67’, ’55’, ’33’, ’12’, ’98’)
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
tuple() method can convert list to tuple.
Solution :
values=input("Enter Values: ") list1 = values.split(",") tup1 = tuple(list1) print(list1) print(tup1)
Question 5 :
Write a program that accepts a comma separated sequence of words as input and prints the words in a comma-separated sequence after sorting them alphabetically.
Suppose the following input is supplied to the program:
without,hello,bag,world
Then, the output should be:
bag,hello,without,world
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution :
items=[x for x in input("Enter Words :").split(',')] items.sort() print(','.join(items))
Question 6 :
Write a program that accepts sequence of lines as input and prints the lines after making all characters in the sentence capitalized.
Suppose the following input is supplied to the program:
Hello world
Practice makes perfect
Then, the output should be:
HELLO WORLD
PRACTICE MAKES PERFECT
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution :
lines = [] while True: s = input("Enter Lines :") if s: lines.append(s.upper()) else: break for sentence in lines: print(sentence) # Leave input blank to stop
Question 7 :
Write a program, which will find all such numbers between 1000 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 on a single line.
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution :
values = [] for i in range(1000, 3001): s = str(i) if (int(s[0])%2==0) and (int(s[1])%2==0) and (int(s[2])%2==0) and (int(s[3])%2==0): values.append(s) print(",".join(values))
Question 8 :
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
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution :
s= input("Enter a Sentence with Digits :") d={"DIGITS":0, "LETTERS":0} for c in s: if c.isdigit(): d["DIGITS"]+=1 elif c.isalpha(): d["LETTERS"]+=1 else: pass print("LETTERS", d["LETTERS"]) print("DIGITS", d["DIGITS"])
Question 9 :
Write a program that accepts a sentence and calculate the number of upper case letters and lower case letters.
Suppose the following input is supplied to the program:
Hello world!
Then, the output should be:
UPPER CASE 1
LOWER CASE 9
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution :
s = input("Enter a Sentence: ") d={"UPPER CASE":0, "LOWER CASE":0} for c in s: if c.isupper(): d["UPPER CASE"]+=1 elif c.islower(): d["LOWER CASE"]+=1 else: pass print("UPPER CASE", d["UPPER CASE"]) print("LOWER CASE", d["LOWER CASE"])
Question 10 :
Write a python program to create a guessing game.
Hints:
Use random module
Solution :
import random # to create a range of random numbers between 1-10 n = random.randrange(1,10) # to take a user input to enter a number guess = int(input("Enter any number: ")) while n!= guess: # means if n is not equal to the input guess # if guess is smaller than n if guess < n: print("number is more than",guess) # to again ask for input guess = int(input("Enter number again: ")) # if guess is greater than n elif guess > n: print("number is less than",guess) # to again ask for the user input guess = int(input("Enter number again: ")) # if guess gets equals to n terminate the while loop else: break print("you guessed it right!!")
