Assessment 6

1.  Find the output :

year=int(input("enter any year to be checked "))

if((year%4==0)and (year%100!=0) or (year%400==0)):

print("Leap year")

else:

print("Not a leap year")

2. Example program on All Arithmetic Operators

3.  Find out the output: (a) “sitha*2.5 (b) 10.2* “rajendra” (c)>>> a=5

>>> a/0

4. Evaluate the following expression:

(a)  d=(x+y)*z**a//b+c where x=1;y=2;z=3;a=2;b=2;c=3 (Explain step by step procedure)

(b)  Find out the output: “Ravi”+15

5. Define the Relational operators

6. Find out the output

a="ravi"

b="Ravi"

print(a>b)

print(a>=b)

print(a==b)

print(a!=b)

7.Write a program for the Expected output: Using Relational Operators

False

False

True

True

False

8. What is Chaining of Relational Operators?

9. What is the output:

(a)  >>> a=10

>>> 5<a<20

(b) >>> a=10

>>> 10<a>20

10.

(a) Write a python program for the following output:

rajendra

rajesh

Hyd

True

False

(b). Find out the output for the following program

a=True

b=False

print(a and a)

print(a and b)

print(b and b)

print(a or a)

print(a or b)

print(b or b)

print(not a)

print(not b)

.

Key:

1. Error

2. Example program on all arithmetic operators

a=10 # value 10 is stored in variable a

b=2 # value 2 is stored in variable b

print('a+b=',a+b) #Addition operator

print('a-b=',a-b)#Subtraction operator

print('a*b=',a*b)#Multiplication

print('a/b=',a/b)#Division operator

print('a//b=',a//b)#Floor Division (integer Division)

print('a%b=',a%b)#Modulus operator Which gives remainder

print('a**b=',a**b)#Exponenet operator

"""output

a+b= 12

a-b= 8

a*b= 20

a/b= 5.0

a//b= 5

a%b= 0

a**b= 100

3. Find out the output:

(a) “sitha*2.5  # Error

Explanation: If we use * operator for strings then we must use one parameter should be integer and other parameter should be string type

(b) 10.2* “rajendra”  #Error , explanation same as above

(c) >>> a=5

>>> a/0 # Error Division by Zero we can not perform in programming language

4. (a)

>>> d=(1+2)*3**2//2+3

d=3*3**2//2+3 #parenthesis evaluated

d=3*9//2+3 #Exponential operator is evaluated

d=27//2+3 #Multiplication, division, and floor divisions are at equal priority

d=13+3 #addition and subtraction are afterwards

d=16 #finally assignment is performed, the value is 16 now stored in variable ‘d’

>>> print(d)

16

>>>

(b.) Find out the output: “Ravi”+15 # Error  right one is: “Ravi”+’15’

5. Relational Operators compares two operands and returns true or false (1 or 0).

We can understand whether two values are same or bigger or smaller, using these operators.

6. Find out the output

a="ravi"

b="Ravi"

print(a>b)

print(a>=b)

print(a==b)

print(a!=b)

Output:

True

True

False

True

7.  Write a program for the Expected output:

a>b #False

a>=b #False

a<b #True

a<=b #True

a==b #False

output:

False

False

True

True

False

8. output

True

True

False

True

""""

Python string comparison is performed using the characters in both strings. The characters in both strings are compared one by one. When different characters are found then their Unicode value is compared. The character with lower Unicode value is considered to be smaller.

9. What is the output:

(a)>>> a=10

    >>> 5<a<20

True

>>>

Here, 5 is less than 10 i.e 5<a so True, and then 10 is less than 20 i.e a<20 so True. Since both the conditions are True, Hence Result is True

(b) >>> a=10

>>> 10<a>20

False

>>>

Here 5 is greater than or equal to 10 is False. But 10 is less than 20 is True. Since we get false and True, the result will be false.

5>=aà5>=10àFalse

a<20à10<20àTrue

False and True so the result is False

10.

(a) Write a python program for the following output:

rajendra

rajesh

Hyd

True

False

Ans:

print("ravi" and "rajendra") # In and operator :1st argument is True so returns 2nd argument i.e rajendra

print("" and "Sitha") #In and operator :1st argument is False so returns 1st argu:  #empty string

print("kiran" and "")#1st argument is True so returns 2nd argument i.e empty (false) i.e empty

print("" or "rajesh) #in OR operator: 1st is False so returns 2nd  i.e #rajesh

print("Hyd" or "") #in OR operator: 1st True so returns 1st “Hyd

print(not "") # not False i.e True

print(not "Vij") #not True i.e False

(b). Find out the output for the following program

a=True

b=False

print(a and a)

print(a and b)

print(b and b)

print(a or a)

print(a or b)

print(b or b)

print(not a)

print(not b)

Ans:

output

True

False

False

True

True

False

False

True
