QUESTIONS

Which data type in Python represents a sequence of characters?

Right Answer:

Strings in Python represent a sequence of characters.

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 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 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.

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

Right Answer:

The code converts the integer “x” to a string using the str() function and then concatenates it with the string “y”. Therefore, the output will be “1020”.

What is the data type of the variable “x” in the following code snippet?
x = 5

Right Answer:

The variable “x” is assigned an integer value, so its data type is Integer.

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.

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

Right Answer:

Lists in Python are used to store collections of items where each item is indexed by a numerical index.

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.
