QUESTIONS

Which data type in Python 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.

Which data type in Python represents a sequence of characters?

Right Answer:

Strings in Python represent a sequence of characters.

What will be the output of the following code snippet?
x = {"a", "b", "c"}
y = {"b", "c", "d"}
z = x & y
print(z)

Right Answer:

The & operator is used for set intersection, which returns the common elements between two sets. Therefore, the output will be {“b”, “c”}.

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 in Python is mutable?

Right Answer:

Lists in Python are mutable, meaning their elements can be changed after they are created.

Which data type in Python is used to represent a true or false value?

Right Answer:

Booleans in Python are used to represent true or false values.

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 = {"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 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.

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.
