20 High-Order Thinking Skills (HOTS) Questions with Solutions – Class 12 Computer Science (Python)
These questions are taken from the below given topics:
- Tokens
- Variable Assignments
- Expressions
- Flow of control
- Strings
- Lists
- Tuples
- Dictioanries
These topics are from the chapter Python revision tour. So let us begin:

c = "Hello"
d = True
print(type(a), type(b), type(c), type(d))[4] What will be the result of the following expression? Explain the order of operations.
result = 10 + 2 * 5 / (3 - 1) ** 2
print(result)[5] Identify the errors in the given program and rewrite the correct code and underline the corrections:
num = int("Enter a number: ")
if num > 0
print("Positive")
else if num < 0:
print("Negative")
else:
print(Zero)Ans.:
num = int(input("Enter a number: ")) #input function is missing
if num > 0: #colon is mising
print("Positive")
elif num < 0: #elif not else if
print("Negative")
else:
print("Zero") #Zero should be enclosed in double quotation[6] What will be the output of the following code:
a, b = 0, 1
for _ in range(4):
print(a, end=" ")
a, b = b, a + b[7] What will be the output of given code:
a = b = c = 100
a += 10
b -= 5
c *= 2
print(a, b, c)[8] What will be the output for the following:

(i) mean()
(ii) randint()
[12] Rewrite the following code in Python after removing all syntax error(s). Underline each correction done in the code.
for Name in <'Rachana','Komal','Kapil','Paresh'>:
IF Name[0]='K':
print(name) Ans.:
for Name in ['Rachana', 'Komal', 'Kapil', 'Paresh']:#Changed to a valid list form
if Name[0] == 'K': #Changed 'IF' to 'if'
#Used == instead of '='
print(name) #Name instead of Name[13] Find and write the output of the following Python code:
v = [11, 20, 33, 40]
for i in v:
for j in range(1, i % 5):
print(j, "*", end="") [14] Which of the following can be used as valid variable identifier(s) in Python ?
(i) elif

(iii) in
(iv) _Total
[15] Rewrite the following code in Python after removing all syntax error(s). Underline each correction done in the code.
NUM1=1234
1=DAY1
for C in range[1,4]:
NUM1+C=NUM1
DAY1=DAY1+2
print(C)
print(NUM1:DAY1)Ans.:
NUM1=1234
l=DAY1 #Replace l with 1
for C in range(1,4): #Replace square brackets with round brackets
NUM1=NUM1+C #Replace lvalue with rvalue
DAY1=DAY1+2
print(C)
print(NUM1,DAY1) #Use comma inplace of colon[16] Rewrite the following code in Python after removing all syntax error(s). Underline each correction done in the code.
Val = int(input("Value:"))
Adder = 0
for C in range(1,Val,3)
Adder=+C
if C%2=0:
Print(C*10)
else:
print(C+10)
print(Adder)Ans.:
Val = int(input("Value:"))
Adder = 0
for C in range(1,Val,3): #Colon is missing
Adder+=C #The operator is incorrect =+ replaced with +=
if C%2==0: #Single equal to is given, required ==
print(C*10) #Print is given, replaced with print
else:
print(C+10)
print(Adder)[17] Find and write the output of the following Python code :
Data = ["P",20,"R",10,"S",30]
Times = 0
Alpha = ""
Add = 0
for C in range(1,6,2):
Times = Times + C
Alpha = Alpha + Data[C-1]+"$"
Add = Add + Data[C]

(iii) like
(iv) | |
(v) is
(vi) ^
(vii) between

Val = Val + 1
Text2 = Text2 + str(Val)
elif Text1[I] >= "A" and Text1[I] <= "Z":
if I + 1 < len(Text1):
