From the following, which function of Python checks whether all characters in a string 's' are alpha numeric?

1. s.allnum()
2. s.isnumal()
3. s.isalnum()
4. s.isalphanum()

Answer

s.isalnum()

Reason — The function isalnum() is used to check whether all characters in a string are alphanumeric (i.e., letters and numbers). It returns True if all characters are either alphabets or digits, otherwise it returns False. The other options are incorrect because they are not valid Python string methods.

A motor drives a small gear with 10 teeth which is connected to a larger gear with 40 teeth. What is the gear ratio?

1. 4 : 1
2. 1 : 4
3. 1 : 2
4. 2 : 1

Answer

4 : 1

Reason — The driving gear is the gear that receives power directly from the motor and moves first. Here, the motor drives the small gear with 10 teeth, so it is the driving gear.

The driven gear is the gear that is moved by the driving gear. Here, the larger gear with 40 teeth is connected to the small gear and rotates because of it, so it is the driven gear.

The formula for gear ratio is:

$\text{Gear Ratio}=\dfrac{\text{Number of teeth on driven gear}}{\text{Number of teeth on driving gear}}$

Substituting the values:

$\text{Gear Ratio}=\dfrac{40}{10}=4$

Hence, the correct answer is 4 : 1.

Which of the following string operators in Python is used to find the length of a string 'a'?

1. len(a)
2. len()

Assertion (A): Robots use actuators for movement.

Reason (R): Actuators sense the environment and convert it to electrical signals.

1. (A) is true but (R) is false.
2. (A) is false but (R) is true.
3. Both (A) and (R) are true and (R) is the correct explanation for (A).
4. Both (A) and (R) are true but (R) is not the correct explanation for (A).

Answer

(A) is true but (R) is false.

Reason — Robots use actuators to produce movement by converting energy into mechanical action, so the Assertion is true. However, sensing the environment and converting it into electrical signals is the function of sensors, not actuators. Therefore, the Reason is false.

Give the output of the following Python code:

msg = "Artificial Intelligence"
print(msg[11:14])

1. tel
2. Int
3. ell
4. gen

Answer

Int

Reason — The given code stores the string "Artificial Intelligence" in the variable msg. Python follows 0-based indexing, where the first character is at index 0.

Index Table:

The statement msg[11:14] performs string slicing, where:

• 11 is the starting index (included)
• 14 is the ending index (excluded)

Thus, characters at index 11, 12, and 13 are selected: 'Int'.

Hence, the output is Int.

The keyword used to include a package or module in a Python program is:

1. export
2. include
3. collect

What will be the output of the Python code given below?

x = "BOARD EXAMINATION"
print(x[0:4:2])

1. BOAR
2. BA
3. OR
4. Error

Answer

BA

Reason — The string "BOARD EXAMINATION" is stored in variable x. Python uses 0-based indexing.

Index Table:

The slice x[0:4:2] means:

• Start from index 0
• Go up to index 4 (excluded)
• Take every 2nd character (step = 2)

So selected indices:
→ 0 → B
→ 2 → A

Thus, the output is BA.

What will be the output of the following Python code?

a = 5
b = 3
print(a > b and b < 3)

Answer

False

Given: a = 5, b = 3

Evaluate the expression: a > b and b < 3

• a > b → 5 > 3 → True
• b < 3 → 3 < 3 → False

Now, True AND False → False (The AND operator returns True only when both conditions are True, otherwise, it returns False.)

Hence, the output is False.

What will be the output of the following Python code?

str1 = 'PYTHON'
print(str1[1:4])

Answer

YTH

The string 'PYTHON' is stored in the variable str1. Python uses 0-based indexing.

Index Table:

The slice str1[1:4] selects characters from index 1 to 3 (excluding 4): YTH

Hence, the output is YTH.

What will be the output of the following Python code?

s = "Great Day"
print(s.count('a'))
print(s.startswith('g'))

Answer

2
False

In the string "Great Day":

1. The statement s.count('a') counts the number of occurrences of lowercase 'a' in the string. It appears 2 times, hence the output is 2.

2. The statement s.startswith('g') checks whether the string starts with lowercase 'g'. Since the string starts with uppercase 'G', it returns False as Python is case-sensitive.

Hence, the output is:

2
False

Explain the role of controllers in a robotic system. How do they work together with sensors and actuators?

Answer

Role of Controller in a Robotic System:

A controller is the main part of a robotic system that manages and controls the overall functioning of the robot. It processes the input received and gives instructions to perform specific tasks.

Working with Sensors and Actuators:

• Sensors collect data from the environment and send it to the controller.
• The controller processes this data and makes decisions.
• It then sends signals to the actuators.
• Actuators carry out the action as instructed by the controller (like movement or operation).

Thus, the controller acts as a link between sensors and actuators, ensuring proper functioning of the robotic system.

Briefly explain supervised learning.

Answer

Supervised learning is a type of machine learning in which the model is trained using a labelled dataset, where both the input data and the correct output are known.
The data is divided into training data and test data. The training data is used to train the model, while the test data is used to check how accurately the model predicts the output for new data.
In supervised learning, the model learns from known results and then predicts the correct output for unseen inputs with good accuracy.
