1An operator able to check whether two values are equal is coded as:
- A=
- B===
- C==
- D!=
2The value eventually assigned to x is equal to:
x = 1
x = x == x- AFalse
- B1
- CTrue
- D0
3How many stars will the following snippet send to the console?
i = 0
while i <= 3 :
i += 2
print(“*”)- Atwo
- Bthree
- Cone
- Dzero
4How many stars will the following snippet send to the console?
i = 0
while i <= 5 :
i += 1
if i % 2 == 0:
break
print(“*”)- Azero
- Bone
- Ctwo
- Dthree
5How many hashes will the following snippet send to the console?
for i in range(1):
print(“#”)
else:
print(“#”)- Aone
- Btwo
- Czero
- Dthree
6How many hashes will the following snippet send to the console?
var = 0
while var < 6:
var += 1
if var % 2 == 0:
continue
print(“#”)- Atwo
- Bzero
- Cone
- Dthree
7How many hashes will the following snippet send to the console?
var = 1
while var < 10:
print(“#”)
var = var << 1- Aeight
- Bone
- Cfour
- Dtwo
8What value will be assigned to the x variable?
z = 10
y = 0
x = y < z and z > y or y > z and z < y- A0
- B1
- CTrue
- DFalse
9What is the output of the following snippet?
a = 1
b = 0
c = a & b
d = a | b
e = a ^ b
print(c + d + e)- A1
- B3
- C2
- D0
10What is the output of the following snippet?
lst = [3, 1, -2]
print(lst[lst[-1]])- A1
- B-2
- C3
- D-1
11What is the output of the following snippet?
lst = [1,2,3,4]
print(lst[-3:-2])- A[2,3]
- B[]
- C[2]
- D[2,3,4]
12The second assignment:
vals = [0, 1, 2]
vals[0], vals[2] = vals[2], vals[0]- Areverses the list
- Bshortens the list
- Cextends the list
- Ddoesn’t change the list
13After execution of the following snippet, the sum of all vals elements will be equal to:
vals = [0, 1, 2]
vals.insert(0,1)
del vals[1]- A2
- B5
- C3
- D4
14Take a look at the snippet, and choose the true statement:
nums = [1,2,3]
vals = nums
del vals[1:2]- Athe snippet will cause a runtime error
- Bnums and vals are of the same length
- Cvals is longer than nums
- Dnums is longer than vals
15Which of the following sentences is true?
nums = [1,2,3]
vals = nums[-1:-2]- Avals is longer than nums
- Bthe snippet will cause a runtime error
- Cnums and vals are of the same length
- Dnums is longer than vals
16What is the output of the following snippet?
l1 = [1,2,3]
l2 = []
for v in l1:
l2.insert(0,v)
print(l2)- A[3,2,1]
- B[1,2,3]
- C[3,3,3]
- D[1,1,1]
17What is the output of the following snippet?
l1 = [1,2,3]
for v in range(len(l1)):
l1.insert(1,l1[v])
print(l1)- A[1, 2, 3, 3, 2, 1]
- B[3, 2, 1, 1, 2, 3]
- C[1, 1, 1, 1, 2, 3]
- D[1, 2, 3, 1, 2, 3]

T = [[3-i for i in range (3)] for j in range (3)]
s = 0
for i in range(3):
s += T[i][i]
print(s)- A4
- B2
- C7
- D6
20What is the output of the following snippet?
