Which of the following is valid arithmetic operator in Python:
(i) // (ii)? (iii) < (iv) and
? Is not a symbol used in python
< is used to check conditions
and is used for boolean
// is used for floor division that’s why the correct answer is //

4. W W W. L I B W R L D . B L O G S P O T. C O M
Identify the valid arithmetic operator in Python from the following.
a) ? b) < c) ** d) and
It is similar to prevous question and yes the answer you chose is correct it’s
c) **

5. W W W. L I B W R L D . B L O G S P O T. C O M
Find the invalid identifier from the following
a) 2two b) two2 c)trues d) true_sl
2two starts with 2 which is numeric thus it is invalid identifier.
Others don’t violate any law so they are valid identifier

6. W W W. L I B W R L D . B L O G S P O T. C O M
Find the invalid identifier from the following
a) MyName b) True c) 2ndName d) My_Name
You should have guessed it after reading the question. Yes, the solution is (c) 2ndName

7. W W W. L I B W R L D . B L O G S P O T. C O M
Evaluate the expression:
if A=16 and B =15 then A//B is
(a) 0.0 (b) 0 (c ) 1.0 (d) 1
(d) 1 is the correct answer because A//B is floor division in which there is no decim
places and 16 is greater than 15.

8. W W W. L I B W R L D . B L O G S P O T. C O M
Write the modules that will be required to be imported to execute the following
functions in Python
(i) floor( ) (ii) randint( )
Try it……………………………………….Yes you got it right it’s math

10. W W W. L I B W R L D . B L O G S P O T. C O M
Evaluate the following expressions:
(i) not(20>6) or (19>7)and(20==20)
(ii) 17%20
(I) The order of preferances is
NOT > AND > OR
so, check the conditions and solve it
(ii) 17%20 gives 17
Since 17 is smaller than 20. It is default setting of python.

11. W W W. L I B W R L D . B L O G S P O T. C O M
Rewrite the following code in python after removing all syntax error(s).
Underline each correction done in the code.
30=To
for K in range(0,To)
IF k%4==0:
print (K*4)
Else:
print (K+3)
To=30
for K in range(0,To):
if K%4==0:
print(K*4)
else:
print(K+3)

12. W W W. L I B W R L D . B L O G S P O T. C O M
What do you understand by the term type conversion? Explain with suitable
example.
Typecasting, or type conversion, is a method of changing an entity from one data
type to another. It is used in computer programming to ensure variables are
correctly processed by a function.
An example of typecasting is converting an integer to a string.
A = “17”
B = int(A)
print(b)
It’s output will be 17. Here we converted “17” string into 17 integer value.

13. W W W. L I B W R L D . B L O G S P O T. C O M
a) Write the names of any two data types available in Python.
b) Name the Python Library modules which need to be imported to invoke the followin
functions :
i) sqrt() ii) randint()
a) String, Integer, Boolean(any two)
b) math

14. W W W. L I B W R L D . B L O G S P O T. C O M
Evaluate the following expressions:
a) 14+13%15
b) b) 50 > 6 and 3 > 13 or not 19 > 2
a) The preferences for arithmetic operators is
+,- -- %,//,/* ----**
13%15 will give 13 since 13 is greater than 15 and the sum will be 27
b) It’s solution will be FALSE. Check previous questions for referance.

15. W W W. L I B W R L D . B L O G S P O T. C O M
Evaluate the following expressions:
a) 6 * 3 + 4**2 // 5 – 8
b) b) 10 > 5 and 7 > 12 or not 18 > 3
a) The steps taken will be in order:
4**2 which will give 16
6*3 which will give 18
16//5 which will give 3
3-8 which will give -5
18+(-5) which will give 13
So the solution is 13.
b) Do it yourself. The solution is FALSE.

16. W W W. L I B W R L D . B L O G S P O T. C O M
Rewrite the following code in Python after removing all syntax error(s).
Underline each correction done in the code.
V=80
for c in range(0,V)
If c%4=0:
print (c*4)
Elseif c%5==0:
print (c+3)
else:
print(c+10)
V=80
for c in range(0,V) :
if c%4==0:
print (c*4)
elif c%5==0:
print (c+3)
else:
print(c+10)

17. W W W. L I B W R L D . B L O G S P O T. C O M
Rewrite the following code in Python after removing all syntax error(s).
Underline each correction done in the code.
Value=30
for VAL in range(0,Value)
If val%4==0:
print (VAL*4)
Elseif val%5==0:
print (VAL+3)
else
print(VAL+10)
Try debugging(removing all errors) yourself. It is important to practice..

18. W W W. L I B W R L D . B L O G S P O T. C O M
Evaluate the following expressions:
a) 5 * 3 + 3**2 % 5 – 8
b) b) 8>5 or 10 > 12 and not 18 > 3
Solve it yourself and comment below to show your participation.

19. W W W. L I B W R L D . B L O G S P O T. C O M
Rewrite the following code in Python after removing all syntax error(s).
Underline each correction done in the code.
Num=int(“Enter a number”)
for N in range(0,Num)
If n%2=0:
print (n*4)
Elseif n%5==0:
Print (n+3)
else
print(n+10)
Do it yourself and Comment the solution below.

20. W W W. L I B W R L D . B L O G S P O T. C O M
Rewrite the following code in Python after removing all syntax error(s). Underline
each correction done in the code.
250 = Number
WHILE Number<=1000:
If Number=>750:
print(Number)
Number=Number+100
else
print(Number*2)
Number=Number+50
It is an easy question. I know that after doing the previous questions it must feel
Boring but let’s do it. Comment below your hardwork.
