QUESTIONS

Which data type in Python is used to store a sequence of characters?

Right Answer:

Strings are used to store sequences of characters in Python.

What is the data type of the variable “x” in the following code snippet?
x = True

Right Answer:

The variable “x” is assigned a boolean value, so its data type is Boolean.

What is the output of the following code snippet?
x = 3.14
print(type(x))

Right Answer:

The code snippet prints the data type of the variable “x”, which is a floating-point number. The correct type name in Python is “float”.

What will be the output of the following code snippet?
x = 10
y = "20"
print(x + int(y))

Right Answer:

The code snippet converts the string “20” to an integer using the int() function and then adds it to the integer value of “x”. Therefore, the output will be 30.

What will be the output of the following code snippet?
x = {"a": 1, "b": 2}
y = {"b": 3, "c": 4}
z = {**x, **y}
print(z)

Right Answer:

The ** operator is used for dictionary unpacking, combining the key-value pairs of two dictionaries. If there are duplicate keys, the value from the second dictionary overrides the value from the first dictionary. Therefore, the output will be {“a”: 1, “b”: 3, “c”: 4}.

What is the output of the following code snippet?
x = 10
y = 20
x, y = y, x
print(x, y)

Right Answer:

This code swaps the values of variables “x” and “y” using tuple unpacking. Therefore, the output will be 20 10.

Which data type is used to store a collection of items, where each item is indexed by a key?

Right Answer:

Dictionaries in Python are used to store collections of items where each item is indexed by a key.

What will be the output of the following code snippet?
x = "Hello"
print(type(x))

Right Answer:

The code snippet prints the data type of the variable “x”, which is a string. The correct type name in Python is “str”.

What will be the output of the following code snippet?

Right Answer:

The clear() method removes all elements from the set.

What is the output of the following code snippet?
x = [1, 2, 3]
y = x.copy()
x.append(4)
print(y)

Right Answer:

The copy() method creates a shallow copy of the list, so changes made to the original list “x” will not affect the copied list “y”. Therefore, the output will be [1, 2, 3].
